## 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-reputation-origin-detector-153e6132
```

Example prompt: Check whether agent ID 7832 has an organic reputation or if it was farmed or burst-boosted — I want to know if its trust score is real before I interact with it.

## When to prefer this

Choose this endpoint when you need to verify whether an AI agent's trust score was organically earned versus artificially inflated through sybil attacks, review farms, or burst campaigns. Prefer it over generic trust-score lookups when the authenticity of the reputation origin — not just the score value — is the critical question. Ideal for agent marketplaces, delegation decisions, or compliance audits where manipulated reputation poses risk.

## Known failure modes

- Agent ID not found on-chain: returns 404 or empty result
- Invalid or non-integer agent_id: validation error from schema
- Agent has insufficient review history for classification: low-confidence or indeterminate result
- Payment failure for x402 micropayment: request blocked before processing
- Rate limiting if too many calls in short succession

## How this service works

Find out if an AI agent's reputation is earned or bought: ORGANIC/FARM/BURST origin detection with sybil forensics

## Output

Returns a reputation origin classification (ORGANIC, FARM, or BURST) for the specified ERC-8004 agent, along with supporting sybil forensics signals such as reviewer concentration patterns, ghost reviewer indicators, and burst timing anomalies that explain how the agent's trust score was accumulated.
