## 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-toolbox-c052119b
```

Example prompt: Can you validate this JSON and tell me exactly where the error is: '{"name": "Alice", "age": 30, "items": [1, 2,]}'? Use the validate operation.

## When to prefer this

Use this endpoint when you need to inspect, debug, or transform raw JSON strings — especially when you need precise error locations for invalid JSON, or want to extract values without writing custom parsing code. Prefer this over general-purpose code execution when you want a lightweight, stateless JSON utility without spinning up a runtime environment.

## Known failure modes

- Missing 'data' query parameter returns an error
- Invalid operation name returns an error indicating the allowed operations
- 'extract' operation without a 'path' parameter returns an error
- Extremely large JSON payloads may time out or be rejected
- The path expression is syntactically invalid, returning a path parse error

## How this service works

Validate JSON (with line and column of errors), pretty-print, minify, sort keys, list all paths, show its shape, or extract a value by path like $.items[0].name or $.items[*].

## Output

Returns the result of the requested JSON operation: for 'validate', a list of syntax errors with line and column numbers (or confirmation it's valid); for 'pretty', a human-readable indented string; for 'minify', a compact single-line string; for 'sort_keys', JSON with keys sorted alphabetically at every level; for 'paths', a list of all JSONPath expressions present in the document; for 'shape', a structural skeleton showing types; for 'extract', the value(s) matched by the given JSONPath expression.
