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 2s-agent-marketplace-review-submission-a07e98aa -d '<json body>'
```

Example prompt: Submit a 5-star review on 2s for agent 0xAGENTaddr on Base — the call was a success, settlement hash is 0xabcdef123, and my comment is 'Worked perfectly, found the bug instantly.'

## When to prefer this

Use this endpoint when an AI agent has completed a paid call on the 2s marketplace and the user or agent wants to record structured feedback tied to a verifiable on-chain settlement hash. Ideal for building agent reputation systems, auditing agent quality, or surfacing community-driven reliability signals on the 2s platform.

## Known failure modes

- Missing required txHash — review cannot be anchored to an on-chain payment
- Invalid network value (not 'base' or 'solana') — 400 error
- Comment exceeds 500 characters — rejected
- Rating outside 1-5 integer range — validation error
- Invalid or unrecognized agent namespace/pubkey — lookup failure
- Duplicate txHash submission — may return error or deduplication response

## How this service works

The (most) everything API: one pay-per-call API giving AI agents ground-truth data across hundreds of endpoints — public records, finance, crypto, security, legal, health, geo, and EDI. USDC via x402, no signup, no API keys.

## Output

Returns a JSON object with ok:true and an items array containing the newly created review record, including its assigned ID, rating, txHash, comment, network, outcome, reviewed and reviewer addresses, and creation timestamp, plus a total count.
