## 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 signaldesk-ai-json-pretty-printer-422a4bec -d '<json body>'
```

Example prompt: Can you pretty-print and sort this JSON for me: {"b":2,"a":1,"c":{"z":9,"m":3}}?

## When to prefer this

Choose this endpoint when you need a simple, deterministic, paid JSON formatting operation — particularly when you want keys sorted alphabetically and consistent indentation. Suitable for quick developer tooling tasks, log normalization, or documentation prep. Prefer this over free local formatters when operating within an x402 micropayment workflow or when you need a remote, stateless transformation step in an agent pipeline.

## Known failure modes

- Malformed or non-JSON input in the data field may return an error or unexpected output
- Deeply nested or very large JSON objects may be truncated due to bounded execution limits
- Rate limits or free quota exhaustion may result in payment rejection or 402 errors
- Non-object JSON values (arrays, primitives) may produce unexpected formatting behavior

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object containing a 'text' field with the input JSON reformatted as a pretty-printed, indented, and alphabetically key-sorted string (e.g. {"text":"{\n  \"a\": 1,\n  \"b\": 2\n}"})
