## 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 ai-rook-json-validate-01028396
```

Example prompt: Can you check if this is valid JSON for me: {"name":"Alice","age":30,"active":true} — I want to make sure there are no syntax errors before I submit it.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call JSON syntax validator with no signup or API key overhead, especially within an agentic workflow that already uses x402 micropayments on Base. Ideal for quick pre-flight checks on JSON payloads, debugging malformed data, or validating user-submitted JSON at $0.002 per call.

## Known failure modes

- Empty or missing input returns an error indicating nothing to validate
- Non-string binary inputs may cause parsing failure
- Payment not received results in HTTP 402 response requiring USDC payment on Base mainnet
- Extremely large JSON payloads may time out or be rejected
- Network errors return standard HTTP error codes
