## 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-onchainexpat-com-a9296b2e -d '<json body>'
```

Example prompt: Give me the full wallet forensics dossier for Ethereum address 0x1234567890123456789012345678901234567890 — I want to see identity info like ENS names and labels, any DeFi positions, and all token approvals.

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call wallet intelligence report covering identity, DeFi exposure, and token approvals together. Prefer it over narrower endpoints when you need a full dossier rather than just identity or just price data. Ideal for due diligence, fraud investigation, or pre-transaction risk checks on an unknown wallet.

## Known failure modes

- Missing X-PAYMENT header returns 402 with payment instructions and accepted asset details
- Invalid or malformed Ethereum address returns an error
- Unsupported chain name returns a validation error
- Address with no onchain history may return sparse or empty results
- Payment amount mismatch or expired payment timeout causes rejection
