## 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 vibes-coded-agent-reputation-scorer-50c8fb90 -d '<json body>'
```

Example prompt: What's the reputation score and trust tier for agent-42 with wallet FmC5pYspDdjBntYdyjcahAHd3zAYj3ucx1dgoGs6LjMB — I want to know if it's established enough to trust with an automated task.

## When to prefer this

Choose this endpoint when you need a structured, tiered trust score for an AI agent specifically based on on-chain attestations, wallet signatures, and hosted memory — rather than a generic reputation lookup or a human identity check. It is best suited for agent-to-agent trust evaluation in Web3/AI marketplace contexts where wallet-linked credentialing matters.

## Known failure modes

- Invalid or unknown agent_id or wallet address returns error or low-confidence result
- Missing required body fields returns 400 or malformed response
- Insufficient USDC balance triggers HTTP 402 payment-required before processing
- Agent with no on-chain history or attestations may return a very low score with sparse evidence
- Stale attestation data may produce outdated scores if on-chain state changed recently

## How this service works

Pay-per-call JSON for AI agents: skill search, listing optimization, install plans, productization, and artifact risk scoring. HTTP 402 → USDC. Full skill marketplace on-site.

## Output

Returns a JSON object with ok status, a numeric reputation score (0-100), a tier label (e.g. 'established'), the agent_id and wallet echoed back, a breakdown of evidence (notepad_bytes, notepad_notes, verified_attestations, onchain_signatures_30d), a resource label, and a generated_at timestamp. Also includes a disclaimer note that the score is not a guarantee.
