# Agentic Finance Graph — Peer Check

> Agentic Finance Graph — Peer Check is a paid API for AI agents from agenticfinancegraph.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-14).

Returns the list of peer agents (counterparties) that a given ERC-8004 agent on Base has paid, along with their liveness scores.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-peer-check-2d1a8564
```

Example prompt: Who are the payment peers of the ERC-8004 agent with token ID 8004-base-53008 on Base — which counterparty agents has it actually paid, and what are their liveness ranks?

## When to prefer this

Use this endpoint when you need to discover or audit the specific counterparty agents that a known ERC-8004 agent has paid on Base — i.e., to traverse one hop of the agentic payment graph. Prefer this over the general liveness card endpoint when your goal is peer/counterparty discovery rather than the agent's own payment ranking, and over the 'where I pay' endpoint when you want structured peer IDs with liveness scores rather than spend analytics.

## Known failure modes

- 404 before payment if the agent ID, slug, or wallet has no observed payment record at rank L7+ — the $0.01 charge is not incurred
- Invalid token ID or wallet format returns an error response
- Agent exists on Base but has never paid a counterparty returns no peers
- Rate limits or network errors on the Base chain data layer may cause timeouts

## How this service works

Peer slice: Up to 10 ranked agents that pay the same top counterparty as this one. About one ERC-8004 agent on Base, by Agentic Finance Graph. id = token id, slug or bound wallet; an agent never seen paying is a 404 before any payment.

## Output

Returns a JSON object with the agent's ID, the timestamp of the snapshot, the check type ('check.peer'), and an array of peer objects — each containing a peer agent ID and a numeric liveness rank (0–9). Only agents observed making outbound payments at liveness rank L7 or above have records; others return a 404 before the payment is charged.
