## 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 one-engine-json-minify-54111709 -d '<json body>'
```

Example prompt: Take this JSON object and minify it into a single compact string with no extra whitespace: {"hello": "world", "count": 2}.

## When to prefer this

Choose this endpoint when you need a cheap, pay-per-call JSON minification utility with no setup, especially within an agent workflow on Base using x402 micropayments. Ideal when you want deterministic, lossless whitespace removal without spinning up a local parser or depending on a free-tier API with rate limits.

## Known failure modes

- Invalid or malformed JSON input may result in an error response or unexpected output
- Missing 'value' field in the request body may return an error
- Non-serializable inputs may cause processing failures
- Network or worker errors may return 5xx responses

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

A JSON response containing a 'text' field with the input value serialized as a compact, whitespace-stripped JSON string (e.g. '{"hello":"world","count":2}').
