## 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 on-chain-agent-reputation-farming-audit-procedure-fbdb5f10
```

Example prompt: Before I pay this agent, can you audit their on-chain reputation and tell me if their transaction history and star ratings look genuine or if there are signs of wash trading, sybil rings, or other farming — give me the verdict tier and confidence level?

## When to prefer this

Choose this endpoint when you need to verify whether a specific counterparty's on-chain reputation signals (transaction count, star ratings, success records) are authentic before committing to a payment or partnership. It is particularly valuable in autonomous agent-to-agent commerce scenarios where no off-chain identity verification is possible and you must rely solely on ledger patterns to assess trustworthiness. Prefer it over generic blockchain explorers when you need a structured verdict tier with confidence scores rather than raw data.

## Known failure modes

- Address or topic not found on-chain — returns ok:false with no ledger data available
- Insufficient transaction history to reach a verdict — low-confidence result with inconclusive tier
- Malformed or missing required query parameters — 400-level error
- Payment not received — 402 Payment Required response blocking the paid result
- Service temporarily unavailable — 5xx error with no verdict returned

## How this service works

A decision procedure for verifying whether a counterparty's on-chain transaction history, star rating, or success record is genuine or farmed. The audit inspects the historical ledger pattern itself for synthetic volume, including wash-trade self-payments, sybil rating rings, paid-review loops, and transaction-count inflation. It returns a verdict tier from verified-genuine to confirmed-farmed, with confidence thresholds and evidence pointers.

## Output

Returns a structured result containing a verdict tier (ranging from verified-genuine to confirmed-farmed), a confidence threshold, a prose decision brief for agents, evidence pointers identifying specific suspicious patterns found, the generation source (llm, reasoning, or deterministic), and an ISO-8601 timestamp of when the audit was generated.
