## 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-json-validate-79abb3a7 -d '<json body>'
```

Example prompt: Can you validate this JSON body I'm about to POST — it's a plain JSON object with fields 'name' and 'email' — and check it against an expected output that looks like {"status": "ok", "id": 123}?

## When to prefer this

Use this endpoint when an AI agent needs to verify that a JSON HTTP request body is correctly structured before dispatching it to a downstream API — especially in automated pipelines where malformed payloads would cause downstream failures. It is particularly useful as a low-cost ($0.001 USDC) pre-flight check. Prefer it over generic JSON linting tools when you need verifiable, pay-per-result delivery with crypto payment via x402 on Base or Solana.

## Known failure modes

- Missing required fields ('input' or 'output') returns a validation error
- Incorrect bodyType enum value (not 'json', 'form-data', or 'text') causes rejection
- Body object that cannot be parsed as JSON results in an error
- Network or payment failure (x402 USDC payment not completed) blocks the request
- Empty or malformed example output object may produce inconclusive results

## How this service works

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

## Output

A JSON object containing the validation outcome — indicating whether the provided request body conforms to the expected structure and output schema. The response is a JSON object (exact shape depends on the validation result).
