## 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 coco-json-format-tool-4bcaaa2c
```

Example prompt: Can you check if this is valid JSON and format it nicely for me: '{"name":"Alice","age":30,"active":true}'?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call JSON validation and formatting tool without standing up your own infrastructure. It is ideal for AI agents that occasionally need to sanitize or verify JSON strings on the fly, especially within a micropayment (x402) workflow where no API key management is desired.

## Known failure modes

- Malformed or non-JSON input may return valid:false with unparseable output
- Missing required 'data' query parameter may result in an error response
- Network or payment-related failures (x402 micropayment not fulfilled) may block the request
- Extremely large JSON payloads may time out or be rejected

## Output

Returns an object containing a 'json' field with the formatted (pretty-printed) JSON string, and a 'valid' boolean indicating whether the input was syntactically correct JSON.
