Shared fee-setting fingerprint

get_fee_fingerprint

Read-onlyIdempotent

Wallets whose transactions pin an identical fee setting — compute-unit price or Jito tip on Solana, priority fee or legacy gas price on EVM chains — one operator's bot settings showing up across every wallet it drives. This is the shared-CONFIGURATION member of the "who is really behind this token" family (proven transfers: get_wallet_links; funding origin: get_funding_sources; behavioural twins: get_lookalike_clusters), not a timing link: it never proves bundling, and two wallets can match days apart. Use it to corroborate get_lookalike_clusters, and to catch the operator who sold their launch wallets and re-entered through fresh ones; read a match as corroboration, never as proof of coordinated buying. Groups are strongest first; pending true means no bundle scan has run for this token yet, so nothing has looked rather than nothing was found. Arguments: address and chain; one API unit on any chain, because it reads what the bundle scan already computed.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`chain`	No	Chain the token is deployed on: solana (default), ethereum, base, bsc, robinhood, arc, hyperevm. Required for any 0x address, because the same contract address can exist on several EVM chains. Omit it for Solana. An unsupported value is rejected before any request is spent; EVM chains need a key on an All-Chains plan.	solana
`address`	Yes	The token's own contract address, exactly as an explorer shows it. Solana: the base58 mint, 32-44 characters (e.g. 6p6xgHyF7AeE6TZkSmFsko444wqoP15icUSqi2jfGiPN). EVM: 0x followed by 40 hex characters, case-insensitive (e.g. 0x6982508145454ce325ddbe47a25d4ec3d2311933). Never a pool, pair, wallet or deployer address — those come back as not found. Set `chain` to match the address: a 0x address alone cannot say which EVM chain it lives on, and a Solana mint sent with an EVM chain is rejected.

Output Schema

TableJSON Schema

Name	Required	Description
`stats`	No	Wallets seen, how many carried a readable fee setting, how many were linked, how many set none.
`token`	No	The address that was scanned (on get_token_scan, the full token metadata object instead).
`groups`	No	One entry per fee setting shared by two or more wallets, strongest first: wallets, supplyPct bought, confidence.
`pending`	No	True when no bundle scan has run for this token yet: nothing has looked, not nothing was found.
`excluded`	No	Fee values suppressed as client defaults, with the wallet count each covered.
`poweredBy`	No	Always "DeFade.org".
`timestamp`	No	ISO time the response was assembled.
`computedAt`	No	When this result was read.
