## 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 json-pretty-printer-e081bc2f -d '<json body>'
```

Example prompt: Can you pretty-print this JSON for me so it's readable? Here's the input: {"a":1,"b":{"c":2,"d":[3,4,5]}}

## When to prefer this

Choose this endpoint when you have a valid but compact or minified JSON string and need it formatted for readability — for display, logging, debugging, or documentation purposes. If your JSON is malformed or broken, use the sibling JSON-repair endpoint first. This endpoint is purpose-built for formatting only and is ideal for agents that need to present structured data in a human-friendly way.

## Known failure modes

- Invalid or malformed JSON input returns an error (for malformed JSON, consider the sibling JSON-repair endpoint first)
- Input exceeding 100,000 characters is rejected
- Empty string input is rejected (minLength: 1)
- Payment failure via x402/Base USDC causes request to be denied

## How this service works

Quality-scored paid utility APIs for AI agents over x402 on Base USDC.

## Output

Returns a JSON object with a `result.formatted` field containing the input JSON re-serialized with standard 2-space indentation and newlines, making nested structures human-readable.
