## 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 minia2a-x402-json-validate-3e771659
```

Example prompt: Can you validate this JSON request structure for me — it's a GET method with a JSON body type and query params like {"userId": "string"}, and the expected output type is object?

## When to prefer this

Use this endpoint when you need to programmatically verify that a JSON-described API request object conforms to expected structure before executing it — especially useful in agentic workflows where requests are dynamically constructed and must be validated before submission.

## Known failure modes

- Missing required 'input' field returns a validation error
- Unrecognized HTTP method value may fail validation
- Malformed queryParams object structure causes parse error
- Network or payment errors (402) if USDC payment not properly provided
- Empty or null input causes schema rejection
