## 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 arch-tools-jsonpath-query-fdfbc0aa -d '<json body>'
```

Example prompt: Run the JSONPath expression $.store.book[*].author against this JSON object I have and give me all the matching author values.

## When to prefer this

Use this endpoint when you need to evaluate a JSONPath expression against a JSON document and get back matching values without writing custom parsing code. Ideal for agents processing API responses, config files, or structured data payloads where specific fields or filtered subsets are needed dynamically at runtime.

## Known failure modes

- Invalid JSONPath expression syntax returns an error
- Path that matches nothing returns an empty array or null result
- Input 'data' field that is not a valid JSON object causes a parsing error
- Missing required fields 'data' or 'path' results in a 400-style validation error
- Deeply nested or very large JSON objects may cause performance issues
