## 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 x402-market-intel-seller-score-fe06165e -d '<json body>'
```

Example prompt: Score the x402 seller at wallet address 0xAbC123... for me — I want to know their revenue proof, how many unique buyers they've had, metadata quality, registry coverage, and route reliability before I autopay them.

## When to prefer this

Use this endpoint when an AI agent needs to vet an x402 paid API seller before committing to autopay — especially when evaluating route reliability, verifying revenue history, or comparing seller trustworthiness across wallets or domains in the x402 ecosystem.

## Known failure modes

- Unknown or unregistered wallet/domain returns low or zero scores
- Malformed payTo address returns validation error
- Insufficient on-chain or registry data yields low-confidence score
- Payment of 0.10 USDC on Base required; unpaid requests return 402
- Rate limiting or network errors from underlying x402 infrastructure

## How this service works
