Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability onchainexpat-x402-wallet-report-b89d3d74 -d '<json body>'

## When to prefer this

Choose this endpoint when you need a pay-per-use, no-subscription wallet research report for due diligence, portfolio review, or onchain investigation. Prefer it over free block explorers when you want a pre-processed, AI-summarized report rather than raw transaction data.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported blockchain network may yield empty or error response
- Insufficient x402 payment results in 402 Payment Required response
- Rate limiting or service unavailability returns 5xx error
- Empty response example in schema means output structure is not guaranteed
