## 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-minifier-b4a65026 -d '<json body>'
```

Example prompt: Can you minify this JSON for me by removing all the whitespace? Here it is: { "name": "Alice", "age": 30, "city": "New York" }

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.01 USDC) server-side JSON minification without implementing your own parser. It is especially useful in agent pipelines where you need to reduce payload size before further transmission or storage, and you want a reliable, stateless utility call rather than running client-side code.

## Known failure modes

- Invalid JSON input — if the input string is not valid JSON, the endpoint may return an error or malformed output
- Empty string input — passing an empty or null json field may result in an error response
- Malformed request body — omitting the json field entirely will likely cause a validation error

## How this service works

Minify JSON by stripping whitespace

## Output

Returns the input JSON string with all insignificant whitespace (spaces, tabs, newlines) removed, producing a compact single-line JSON string that is semantically equivalent to the input.
