## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentic-finance-graph-pre-check-erc-8004-agent-lookup-a47f5d20
```

Example prompt: Before I send USDC to 0x0e84ddedaae6a779c462c22a59f301ec31b6b808 from agent 8004-base-53008, can you run a pre-check to see if this agent is ranked L7 or above, has any live incidents, and whether it has paid that address before?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
