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 sweetai-agent-reputation-forensics-eca6eb06
```

Example prompt: Before I pay this agent, can you check if its ERC-8004 reputation is real or bought — run the Sybil forensics and tell me if the reviews look organic, farmed, or burst-purchased?

## When to prefer this

Use this endpoint when you need to verify whether an AI agent's on-chain reputation is authentic before trusting, paying, or integrating with it. Prefer this over generic trust checks when you specifically want Sybil forensics — reviewer concentration analysis, ghost reviewer detection, and burst-purchase pattern flags — against the ERC-8004 reputation registry. It is equivalent to /api/v1/trust-forensics on the same host.

## Known failure modes

- Agent identifier not found in ERC-8004 registry — returns not found error
- Invalid or missing required query parameters — returns 400 bad request
- Payment not received or x402 payment flow incomplete — returns 402 Payment Required
- Rate limit exceeded for the endpoint — returns 429
- ERC-8004 registry temporarily unavailable — returns 503 or timeout

## How this service works

Check an AI agent's reputation before you trust it: is this agent's reputation earned or bought? Sybil forensics over the ERC-8004 reputation registry — reviewer concentration, ghost reviewers, burst detection flags bought feedback. Optional limit=N. Same handler and price as /api/v1/trust-forensics. No account, no API key

## Output

Returns a Sybil forensics report for the queried ERC-8004 agent including an origin classification (ORGANIC/FARM/BURST), reviewer concentration metrics, ghost reviewer detection flags, and burst-buying pattern signals that indicate whether the agent's reputation was earned legitimately or purchased.
