## 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 delx-commerce-x402-openapi-route-check-9de61e74 -d '<json body>'
```

Example prompt: Check if this OpenAPI operation object is properly configured for x402 pay-per-result — I need to know if it has the 402 response and all required fields, and which ones are missing if any.

## When to prefer this

Choose this endpoint when you need a lightweight, verifiable, pay-per-use check that an OpenAPI route operation is correctly configured for x402 payments — especially when you want cryptographic evidence (input hash) without retaining data, and when you need a deterministic pass/fail result rather than general OpenAPI linting.

## Known failure modes

- Malformed or missing operation object results in validation error
- Operation object exceeds 128 properties limit causing rejection
- Network or service error returning non-200 response
- x402 payment not fulfilled resulting in 402 payment required before result is returned

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object with a boolean 'valid' field, a 'checks' object indicating whether a 402 response is present and required fields are present, a list of 'missing_fields', a 'status' of pass or fail, and an 'evidence' object containing a SHA-256 hash of the input and confirmation that no data is retained externally.
