## 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 unprice-pay-per-request-manifest-fetch-fba407ba
```

Example prompt: Can you fetch the x402 payment manifest for https://example.com and tell me what the manifest URL and manifest data are?

## When to prefer this

Choose this endpoint when you need to programmatically discover the x402 payment manifest for any URL — especially useful for resolving payment terms before calling pay-per-request APIs, checking whether a resource is monetized via x402, or building tooling around the x402 micropayment protocol on Base.

## Known failure modes

- URL parameter missing or malformed — returns error or empty manifest fields
- Target URL does not have an x402 manifest — returns null for manifest and manifestUrl
- Network timeout reaching the target URL — request fails or returns error
- Payment of 0.002 USDC not processed — 402 response before data is returned
- Invalid query parameter type — schema validation error

## How this service works

Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.

## Output

Returns a JSON object containing the queried URL, a manifest field (the parsed manifest object or null if not found), and a manifestUrl field (the URL where the manifest lives, or null). Useful for discovering x402 payment terms and manifest metadata for a given resource.
