# x402 infra for agents.Pay, invest and earn in USDC.

Agents pay per call. We build the rails they pay on: 51 paid endpoints live on Base, a treasury layer that keeps agents funded, and storefronts that let your agent earn.

## Agents are a new kind of buyer

- Software now holds a wallet. An agent can read a price, sign a USDC authorization on Base and retry the call. No account, no card, no invoice.

- The 402 is the storefront. x402 turns HTTP 402 Payment Required into a machine-readable quote: amount, asset, network, payTo. Discovery lives in llms.txt, agents.md, openapi and /.well-known/x402.

- Buyers leave at the first inconsistency. A sample at an old price, a 402 on garbage input, a charge on a timeout. Agents do not file tickets. They move to the next endpoint.

- Trust is the product. Never charged on failure. The body is released only after settlement. The same signed request gets the same result again, free. We run that contract in production, and we sell it.

## Pay. Invest. Earn. One loop.

Most agent stacks stop at the wallet. Ours runs end to end: the agent pays for what it needs, a treasury keeps it funded and inside its limits, and its own endpoints earn it back from other agents.

## One request. One payment. One receipt.

Every endpoint, from a $0.002 tip to the $2,500 white-label pack, follows the same five steps. The buyer can check each one.

- 01QuoteGET the URL unpaid. The 402 carries the price in the PAYMENT-REQUIRED header (x402 v2) and in accepts (v1). Free.

- 02CheckConfirm availability is ready, the amount and payTo match, and the amount fits your client's per-payment limit (default $1).

- 03SignSign an EIP-3009 USDC authorization on Base for the exact amount. The facilitator pays gas, so the buyer needs no ETH.

- 04SettleWe verify, do the work and save it, then settle at most once. A 4xx or 5xx is never settled.

- 05ReceiptA 200 with the result and a free status_url. Re-send the identical signed request and get it again, free.

Before you sign
- Default x402 clients stop at $1. Set your client's per-payment limit (spendControls.maxAmountPerPayment) to at least $2,500.00 before paying.
- Verify the payTo against the live 402 quote, never against explorer history.
Includes
- The scrubbed production x402 starter kit zip, inline in the 200 body (same sha256 as the $49 kit) as the code base
- White-label build of the rails you pick at intake (e.g. Solana token verdict/kit, EVM gas/fee/precheck/receipt rails, Polymarket kit, prepaid meter) under your domain, brand and payTo
- Deploy hardening (Caddy, systemd, CDP + PayAI facilitator failover, never-charged-on-failure, idempotent receipts) on your infra
- Discovery listings for your host: llms.txt, agents.md, openapi x-guidance, .well-known/x402, Bazaar metadata
- Handover call + 30 days of email support (abhay@avasis.ai)Excludes
- Hosting fees on your infra
- Custody of funds or private keys (you keep your own payTo)
- Smart-contract audits or exploit PoCs
Guarantees
- Never charged on failure: any 4xx/5xx is not settled; a failed settlement is a 402.
- Idempotent: identical signed request re-sent = same receipt free.

# Pay-per-call APIs for AI agents

53 paid endpoints on agents.avasis.ai, each one priced in USDC on Base and paid over x402. Token safety verdicts, pre-sign wallet checks, payment receipts, gas, web reads, odds and pump.fun launch intel. No account, no API key: your agent quotes for free and pays per call.

from $0.002USDC per call · Base · x402 v1 + v2
[See the catalog](https://avasis.ai#catalog)[llms.txt](https://agents.avasis.ai/llms.txt)[openapi.json](https://agents.avasis.ai/openapi.json)

## One request. One payment. One receipt.
x402 puts the price in the HTTP 402 answer. Your client pays it and repeats the request; the server settles only after it has a 2xx answer for you.

- Quote for free. An unpaid GET answers HTTP 402 with the exact price, asset and payTo in the PAYMENT-REQUIRED header (x402 v2) and in the body's accepts (x402 v1).

- Pay one exact amount. USDC on Base (eip155:8453, asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) to 0x6264191D6dD5427435B5E829077842e130Ef1fc8. No account, no API key, no subscription.

- Charged only on success. Invalid input (400), not found (404), rate limited (429), busy (503), timeout (504) and upstream errors are never settled.

- Never pay twice. Paid answers carry an operation_id and a free status_url; replaying the same signed request recovers the result.

Quote, then pay:

```
# 1. quote (free): the 402 carries the price in the PAYMENT-REQUIRED header
curl -i https://agents.avasis.ai/v1/tip/base-gas
# 2. pay with any x402 client: it signs a USDC (EIP-3009) authorization and repeats the GET
npx agentcash@latest add https://agents.avasis.ai
# 3. or let your MCP client discover the catalog (free, read-only)
claude mcp add --transport http avasis https://agents.avasis.ai/mcp
```

## Every paid endpoint, live prices
Prices below are read from the live catalog at build time (2026-11-06). The 402 quote is always authoritative. Path parameters are shown as {mint}; query inputs are documented in openapi.json. (/health counts 51 products on the main server; the 2 pump.fun routes run on a sidecar behind the same host.)

## Pay from JavaScript in five lines
The same snippet pays any endpoint. Swap the URL; the client reads the price from the 402.

@x402/fetch:

```
// npm i @x402/fetch @x402/evm viem   (wallet needs a little Base USDC, no ETH: the facilitator pays gas)
import { wrapFetchWithPayment, x402Client } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const signer = privateKeyToAccount(process.env.X402_PRIVATE_KEY);
const pay = wrapFetchWithPayment(fetch, new x402Client().register("eip155:8453", new ExactEvmScheme(signer)));
const r = await pay("https://agents.avasis.ai/v1/tip/all"); // 402 -> sign $0.002 -> 200 JSON
console.log(r.status, await r.json());

## Questions builders ask

- Do I need an account or an API key?
No. Every endpoint is paid per call over x402 with USDC on Base. The 402 quote is free, and any x402 v2 or v1 client can pay it.

- What happens if a call fails?
You are not charged. Settlement runs only after a 2xx answer; 400, 404, 429, 5xx and timeouts are never settled.

- Why does my x402 client refuse a price above $1?
Default x402 buyers cap one payment at $1. Calls under $1 work as is; for a larger ticket raise maxAmountPerPayment in your client, or buy a prepaid credit pack once at [/meter/](https://avasis.ai/meter/).

- Where is the machine-readable catalog?
[/.well-known/x402](https://agents.avasis.ai/.well-known/x402), [openapi.json](https://agents.avasis.ai/openapi.json), [llms.txt](https://agents.avasis.ai/llms.txt) and [agents.md](https://agents.avasis.ai/agents.md) on agents.avasis.ai. They are generated from the same live product table as the 402 quotes, so prices always match.

# Solana rug check API

Is this token safe? SAFE / WARN / DANGER for any Solana mint or pump.fun coin, with a 0-100 risk score and the on-chain evidence for every flag. $0.01 per call in USDC on Base over x402. No account, no API key.

$0.01USDC per verdict · deeper packs up to $5.00
[Free real verdict](https://agents.avasis.ai/v1/verdict/sample)[Free complete-kit sample](https://agents.avasis.ai/v1/kit/sample)[agents.md](https://agents.avasis.ai/agents.md)

## A deterministic rubric, not a vibe
Every flag carries its evidence and provenance (RPC method, slot, time), so an agent can show its work.

- Mint and freeze authority. Live or renounced, read from the mint account.

- Token-2022 traps. Permanent delegate, transfer hook, transfer fee, default-frozen, pausable, non-transferable.

- Holder concentration. Top-10 share with the pump.fun curve, AMM pools and burn addresses excluded; the largest wallet; identical-balance clusters (a bundle or airdrop-farm signal).

- pump.fun curve. Bonding-curve progress and graduation, so a fresh launch is not mistaken for a mature pool.

- Receipt. operation_id, free status_url, a share page and a PNG card for every paid verdict.

## From a $0.01 screen to a deep pack
Start with the verdict; step up only when an agent needs the holder list, the creator's trades or a batch.

## Also sold to agents on Virtuals ACP
The same verdict code (vendored byte-identical) runs as an Avasis seller on Virtuals ACP v2: Solana and Base/Ethereum token verdicts at $0.10 a job, a token watchlist report at $0.25. Status: live in the ACP sandbox since 6 Nov 2026, pending graduation, so it is not yet listed in Butler search. On x402 the verdict is live today.

## Questions builders ask

- Is the verdict financial advice?
No. It describes on-chain configuration and holdings: authorities, Token-2022 extensions, holder concentration and the pump.fun curve. It is a structural screen, not an audit or a price call.

- Where does the data come from?
Public Solana RPC at request time (cached 20 to 45 seconds per mint). The complete kit adds Jupiter, RugCheck and Dexscreener as second opinions and reports where they disagree.

- What if the address is not a token?
Not a mint: 404, never charged. Garbage input: 400 before any payment challenge.

- Why does my x402 client refuse a price above $1?
Default x402 buyers cap one payment at $1. Calls under $1 work as is; for a larger ticket raise maxAmountPerPayment in your client, or buy a prepaid credit pack once at [/meter/](https://avasis.ai/meter/).

[openapi.json](https://agents.avasis.ai/openapi.json)[agents.md](https://agents.avasis.ai/agents.md)

## Launch provenance, per mint
From the QuantBase launch tape, which listens to every pump.fun launch and graduation.

- Creator history. Prior launches and graduations by the same creator; a SERIAL_LAUNCHER flag.

- Funding cluster. Size of the wallet cluster that funded the creator, its launches, organic vs instant graduations and a rug proxy.

- Bundled graduation. INSTANT_GRAD_BUNDLE when a coin graduates within 2 seconds of creation: a bundled self-buy, not organic demand.

- Clone metadata. Image dHash and 7-day name/symbol collisions: CLONE_METADATA.

- Minutes to graduate, socials presence and the 14-day base rates in the same answer.

## The priors a memecoin rule has to beat
Example answer (as of 2026-11-03 04:22 UTC): 14,872 launches in 24 h, 994 graduated, 434 of them instantly. Over 14 days, 2,852 of 261,566 launches graduated organically (1.09%).

## pump.fun endpoints and the checks around them

**pump.fun and Solana launch checks**
| | Endpoint | USDC per call
| GET /v1/sol/launch-provenance/{mint}pump.fun launch provenance (creator history, funding cluster, clone metadata, instant-graduation bundle) | $0.02
| GET /v1/sol/pumpfun-base-ratespump.fun base rates (organic graduation rate, P(up 1h / 24h), liquidity alive 1h) + 24h launch counts | $0.01
| GET /v1/sol/rug-lite/{mint}Solana rug check lite: authorities, Token-2022 traps, top-10, curve | $0.02
| GET /v1/sol/token-verdict/{mint}Solana token verdict: SAFE / WARN / DANGER + share card + receipt | $0.01
| GET /v1/sol/risk-pack-batchSolana rug-risk pack batch (2-10 mints) + bundle check | $5.00

## Questions builders ask

- Does it detect bundlers and snipers?
It flags launch-level bundle signals: INSTANT_GRAD_BUNDLE (graduated within 2 seconds of creation, a bundled self-buy), funding-cluster stats for the creator, identical-balance clusters in the top holders, and shared creators or top-20 wallets across mints in the batch pack. It does not sell a list of sniper wallets.

- How fresh is the data?
The launch tape feed is delayed about 10 minutes and base rates are cached 10 minutes. Coverage starts around 9 Oct 2026. Fields the tape lacks are null, never estimated.

- What if the mint is unknown?
Unknown mint: 404, never charged.

- Do I need an account or an API key?
No. Every endpoint is paid per call over x402 with USDC on Base. The 402 quote is free, and any x402 v2 or v1 client can pay it.

# Pre-sign checks for agent wallets

An agent that signs needs a second opinion first. Simulate a transaction, decode calldata, check an x402 / EIP-3009 authorization, screen an address and verify a payment on Base or Ethereum, $0.02 per check in USDC over x402.

$0.02USDC per check · Base + Ethereum
[Catalog](https://avasis.ai/x402-api/)[agents.md](https://agents.avasis.ai/agents.md)

## Five questions before a signature

- What will this transaction do? tx-precheck simulates it and answers SIGN / CAUTION / BLOCK; calldata-decode names the function and arguments (an unlimited approve is flagged).

- Should I sign this x402 payment? authorization-check checks an EIP-3009 authorization against the quote you were given: payTo, amount, asset, network and validity window.

- Is it safe to pay this address? address-screen checks the OFAC SDN list and contract facts; look-alike (address-poisoning) addresses are a real pattern on Base.

- Is a spender already approved? erc20-allowance answers for how much.

- Did my payment land? payment-verify and tx-receipt answer settled / pending with the decoded transfers; tx-unstick explains a stuck nonce.

## Questions builders ask

- Do these checks sign or send anything?
No. They read and simulate only. Your agent's keys never leave your client; you send the unsigned transaction or authorization fields, and the check answers before you sign.

- Which chains?
Base (eip155:8453) and Ethereum mainnet (eip155:1). Payment for the check itself is always USDC on Base.

- Do I need an account or an API key?
No. Every endpoint is paid per call over x402 with USDC on Base. The 402 quote is free, and any x402 v2 or v1 client can pay it.

- What happens if a call fails?
You are not charged. Settlement runs only after a 2xx answer; 400, 404, 429, 5xx and timeouts are never settled.

# Monetize your API with x402

Charge AI agents per call in USDC on Base. We run 53 paid endpoints in production; the $49.00 starter kit is that server as a zip, the $0.25 audit lints your live 402, and the white-label pack deploys the whole stack under your brand and payTo.

$49.00starter kit · USDC on Base · one-time
[Starter kit](https://avasis.ai/starter-kit/)[Audit my endpoint](https://agents.avasis.ai/v1/x402/audit/info)[White-label](https://avasis.ai/white-label/)

## What breaks x402 sales (from our own logs)
Each of these cost us real sales before we fixed it. The audit checks for all of them.

- Keep the payment description at 500 characters or less. Coinbase CDP rejects a longer resource.description at verify and settle, while its validator still says valid.

- Keep the 402 response headers under 16 KB. Node's fetch (undici, used by every @x402/fetch buyer) fails on larger headers that curl reads fine. A big example in the Bazaar extension is the usual cause.

- Stay under the $1 default. Default x402 buyers refuse a single payment above $1, so a $49 product needs the buyer to raise maxAmountPerPayment, and the page must say so.

- Never 402 a method your OpenAPI does not declare. Directory crawlers probe every method on the template URL and read an undeclared 402 as a missing input schema.

- Validate before you challenge. A buyer who signs for garbage input and then gets a 400 does not come back. Answer bad input with 400 before the 402.

- Settle only after success. Hold the body until the settle succeeds, never charge a 4xx or 5xx, and give every paid answer a free status URL.

## Questions builders ask

- What is x402?
An open HTTP payment standard: the server answers 402 Payment Required with a machine-readable price, the client pays (USDC on Base here, through a facilitator such as Coinbase CDP) and repeats the request. No accounts or API keys.

- Do I need my own wallet?
Yes. You keep your own payTo address; the kit and the white-label pack never route your revenue through Avasis.

- How do agents find my API?
Publish /.well-known/x402, openapi.json with x-payment-info, and llms.txt, then register on x402scan and the CDP Bazaar (indexed after your first settle). The starter kit ships example files and DIRECTORIES.md.

# pump.fun launch data, ready to license

Per-launch evidence about how every pump.fun token was launched: who bought in the first slots, how many were bundled, serial snipers or shared a funder, and what the creator did. Live API calls, daily csv.gz files, a $199 30-day licence and a $999 full history. Pay in USDC over x402; no sales call. Data and risk tooling, not trading advice.

from $0.002per call · files from $5 · licence $199 / 30 days
[Free samples](https://avasis.ai#samples)[Pricing](https://avasis.ai#pricing)[Datasheet](https://agents.avasis.ai/v1/sol/launch-intel/sample-files/DATASHEET.html)

## What is in it
Derived from public Solana chain data only. Mint, symbol and creator wallet are on-chain; there is no personal or off-chain data.

- Identity: mint, symbol, creator wallet, launch time, graduation time. Public chain data only; symbols are cleaned (NFKC, hidden and control characters removed).

- Launch evidence: supply bought in the first 2 slots, buyers in the creation slot, first 2 slots and first second, serial snipers (early buyers seen sniping other launches), bundled transactions and wallets, shared-funder groups, early buyers funded by the deployer.

- Creator: prior launches and graduations, dev launch buy, dev sold by 10 min, lifetime totals and the funding cluster (size, launches, graduations).

- Clone detection: name, symbol and image collisions with other launches in the last 7 days.

- Label: verdict SAFE / WARN / DANGER with reason_codes from published fixed thresholds (see the rules at [launch-intel/info](https://agents.avasis.ai/v1/sol/launch-intel/info)). No evidence is never SAFE.

**What is in the data**
| | Item | Value
| Chain and venue | Solana, pump.fun bonding-curve launches
| Launches per day | about 31,000 to 40,000 token rows a day (30 Oct to 5 Nov 2026: 30,949 / 31,704 / 30,885 / 34,926 / 34,569 / 40,269 / 34,788)
| How far back | continuous from 30 Aug 2026, when the launch tape started recording (that first day is partial): about 1.7 million launches so far, one more day each night. Nothing earlier exists as a continuous record
| Launch-tape features | batch features cover 70 to 83% of launches a day in the last week of the sample; the rest are labelled no_tape_features
| Live trade tape | real time with about 6 h rolling retention; the first 30 s after a launch are read live
| Batch features land | about 90 min after a launch (median, measured)
| Creator records | lifetime launches and graduations per creator wallet, plus funding-cluster totals
| Holder snapshot | RugCheck top-10 share, only after graduation (81 of 7,430 sample rows)

## Check it before you pay
Every number here can be tested without paying. The 7-day sample is a deterministic 1-in-32 sample of 30 Oct to 6 Nov 2026 (7,430 launches); a mint is in when int(md5(mint)[0:8], 16) % 32 == 0, so you can re-derive the set.

## Any x402 client, or an invoice
x402 means the price is in the HTTP 402 answer and your client signs a USDC authorization; the server settles only after your file or token is delivered. Prefer an invoice? Write to [abhay@avasis.ai](mailto:abhay@avasis.ai) and we send a USDC invoice on Base.

Quote, pay, use:

```
# 1. quote (free): the 402 carries the exact price in the PAYMENT-REQUIRED header
curl -i https://agents.avasis.ai/v1/sol/launch-intel/license-30d
# 2. pay with any x402 client, e.g. AgentCash, or the code on the right
npx agentcash@latest add https://agents.avasis.ai
# 3. the licence answer carries a bearer token: use it on every licensed route
curl -H 'Authorization: Bearer qbp_...' https://agents.avasis.ai/v1/sol/launch-firehose?since=2026-11-06T09:00:00Z
```

@x402/fetch:

```
// npm i @x402/fetch @x402/evm viem   (wallet needs Base USDC; the facilitator pays gas)
import { wrapFetchWithPayment, x402Client } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const signer = privateKeyToAccount(process.env.X402_PRIVATE_KEY);
// default x402 clients refuse a single payment above $1: raise your client's per-payment limit (maxAmountPerPayment)
// to at least $199 before you sign; the exact price is in the 402 quote
const pay = wrapFetchWithPayment(fetch, new x402Client().register("eip155:8453", new ExactEvmScheme(signer)));
const r = await pay("https://agents.avasis.ai/v1/sol/launch-intel/license-30d");
console.log(r.status, await r.json());  // token, expiresAt, fair-use limits
```
Payments above $1 need a raised maxAmountPerPayment in default x402 clients (shown in the code). Pay-to address: 0x6264191D6dD5427435B5E829077842e130Ef1fc8 (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base).

## What this data is not

- Risk evidence, not a prediction. In the 7-day sample, DANGER launches graduated more often (130 of 2,341, 5.6%) than WARN (1.0%) or SAFE (1 of 1,305). Launches that take off attract snipers, bundles and early concentration, and the holder check exists only for graduates. A verdict describes how a launch was run, not whether its price will rise. Do not trade on it.

- Heuristics. Snipers, bundles and funder links are inferred from observed transactions. A wallet seen for the first time has no sniping history.

- Coverage. Batch features cover 70 to 83% of launches in the last week; a launch with no trades in its window has no features and can only be WARN or DANGER. 61 sample rows have a tape gap (tape_complete=false).

- Freshness. Batch features land about 90 min after a launch. Fresh launches are answered from the live 30 s window, and the answer says what was not evaluated. The live tape keeps about 6 h; older launches come from batch features only.

- Not in the data: the dev's current balance (the paid token verdict reads live holders), prices, and any personal data.

- History starts 30 Aug 2026. The tape recorded continuously from 30 Aug 2026 (the first day is partial), so the archive covers about 68 days and 1.7 million launches today and grows by one day each night. About 220 older token rows (2021 to Aug 2026) are stray, not a continuous record, and are not included. We do not hold earlier months.

## If something goes wrong

- Failed delivery is not charged. A file is settled only after the last byte has been handed to your connection. A dropped stream, an unknown date or invalid input is never settled.

- Paid but not delivered: free re-delivery (up to 3 times within 72 h) with an EIP-191 signature from the paying address at POST /v1/redeliver, or a refund to the paying address within 14 days at POST /v1/refund. Terms: [/v1/refund/info](https://agents.avasis.ai/v1/refund/info).

- A re-delivery is the same bytes you bought (same sha256 as the catalog lists). A refund claim unlocks one free re-delivery; you get the data or the money, not both.

- Licence tokens and the history link: if the token or the link is not in the answer you received, claim the same way. Refunds are reviewed by a person; amounts above $1 are never auto-paid.

## Licence terms in five lines

- 1. Internal use. You may use the data inside your organisation for research, risk tooling, backtests and model features.

- 2. No resale. You may not resell, sublicense or republish the files or the API output, or serve them to third parties, without an enterprise licence.

- 3. Derived results are yours. Statistics, charts and models you build from the data are yours to publish. Do not publish raw rows.

- 4. Source and no advice. Public Solana chain data processed by Avasis and QuantBase. Risk evidence, not financial advice and not a prediction. Provided as is, no warranty of completeness.

- 5. Enterprise. Resale, redistribution, embedding, custom exports or an SLA: write to [abhay@avasis.ai](mailto:abhay@avasis.ai).

## Questions buyers ask

- What is the schema?
37 columns, listed with meanings in the [datasheet](https://agents.avasis.ai/v1/sol/launch-intel/sample-files/DATASHEET.html) and at https://agents.avasis.ai/v1/sol/launch-intel/dataset/schema. Every file has the same header; there are no hidden columns.

- How fresh is it?
Daily files cover finished UTC days and are rebuilt every night. The firehose and the per-call checks are live: a fresh launch is evaluated from its first 30 seconds, and batch features (bundles and funder groups) land about 90 minutes later.

- What does coverage look like?
About 31,000 to 40,000 launches a day. Batch tape features exist for 70 to 83% of them in the last week; the rest are labelled no_tape_features. There is no earlier history (the archive starts 30 Aug 2026).

- Can I check quality before paying?
Yes. The 7-day sample (7,430 launches, a published 1-in-32 rule) is free, and so are the live sample calls and the catalog with row counts and sha256 for every file. Download, check and then buy.

- How do I pay without an x402 client?
Write to [abhay@avasis.ai](mailto:abhay@avasis.ai) for a USDC invoice (Base). The checkout on this page is x402: any x402 client or agent can pay; no account, no API key.

- What is the fair-use limit on the licence?
Per token and UTC day: 2 requests per second (burst 10), 20,000 API calls (trap check, creator, firehose polls) and 100 file downloads, plus 2 SSE streams. Hitting a limit answers 429 and is never charged. Need more? Write to abhay@avasis.ai.

- Is this financial advice?
No. It is risk evidence about how launches were run. It does not predict price and is not a signal to buy or sell.

- Can I resell it or put it in my product?
Not with the self-serve licence. That needs an enterprise licence: write to [abhay@avasis.ai](mailto:abhay@avasis.ai).
