01 / What it checks

A deterministic rubric, not a vibe

Every flag carries its evidence and provenance (RPC method, slot, time), so an agent can show its work.

  1. 01

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

  2. 02

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

  3. 03

    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).

  4. 04

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

  5. 05

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

02 / Endpoints

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.

04 / Other rails

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.

05 / Questions

Questions builders ask

  1. Q1

    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.

  2. Q2

    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.

  3. Q3

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

  4. Q4

    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/.
