How this service works
Check before you pay: The routine check before an agent pays or hires another: its level and last observed payment, open incidents, its latest statement (how old, chain intact, flags) and, with payto=<address>, what that address is: label and basis, contract or plain key, how many registered agents paid it, whether this agent paid it before, and whether our poisoning watch saw it planted as a look-alike. Facts only, never a verdict. About one ERC-8004 agent on Base, by Age…
Output
Returns a JSON object with the agent's trust level (L0–L9), last payment timestamp, live and logged incident counts, statement freshness metadata, and — if a payee address was supplied — the payee's label, account type, x402 seller status, number of other agents that paid it, whether it was planted as a lookalike, and whether this agent has paid it before.
Example use cases
Pre-screen agent before USDC payment
“I'm about to pay 50 USDC from agent token 8004-base-53008 to 0x0e84ddedaae6a779c462c22a59f301ec31b6b808 — can you pre-check the agent's rank and confirm that address isn't a lookalike or flagged counterparty?”
Verify agent liveness for automation pipeline
“Can you check the liveness level and incident status of the ERC-8004 agent at wallet 0x0e84ddedaae6a779c462c22a59f301ec31b6b808 on Base to make sure it's active and trustworthy before we route payments through it?”
Audit agent trust rank for compliance
“Pull up the pre-check for ERC-8004 token ID act_8453_53008 and tell me what level it's at, how many incidents it has logged, and when its last payment was — I need this for an on-chain agent compliance review.”
Technical details
Endpoint
GEThttps://agenticfinancegraph.com/check/precheck?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, structured trust signal about an ERC-8004 agent on Base before executing a USDC payment — especially when you want to cross-check both the sending agent's rank and the destination address's reputation in a single call. Prefer it over the full operator pack when you only need a lightweight go/no-go signal rather than detailed paygraph or drain analysis.
Side effects
- 404 returned if agent has never made a counted payment (rank below L7) or if the token ID / wallet is unrecognized
- Invalid or malformed wallet address or token ID results in a 400 or empty response
- Stale statement data if the agent hasn't been active recently (statement.stale=true)
- Payee enrichment unavailable if optional 'payto' address is omitted
- Payment required (402) if the $0.05 USDC fee is not settled via x402
