## 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 jsonpath-extract-e4cdfc11
```

Example prompt: I have a JSON document with a nested store structure — can you run the JSONPath expression $.store.book[*].author against it and tell me all the matching values and how many there are?

## When to prefer this

Choose this endpoint when you need to query or extract data from a JSON document using standard JSONPath syntax, especially when the document has deeply nested structures, arrays requiring negative indexing, wildcard traversal, or keys containing spaces. Ideal for agents that receive raw JSON API responses and need to pull out specific fields without writing custom parsing code. At $0.01 per call it is cost-effective for one-off or low-frequency extraction tasks.

## Known failure modes

- Invalid JSONPath expression syntax returns an error
- Malformed or unparseable JSON document causes a parse failure
- No matching nodes found returns an empty result set with count zero
- Missing required input parameter returns a 400-level error
- Payment not included or insufficient funds results in a 402 Payment Required response

## How this service works

JSONPath extraction: evaluates a path like $.store.book[*].author, $..price, $.items[-1], $['key with spaces'] against a JSON document and returns all matching values with a count. Handles recursive descent, wildcards, negative indexes and bracket keys. $0.01 per query.

## Output

Returns all values matched by the JSONPath expression within the provided JSON document, along with a count of how many matches were found. Supports recursive descent (..), wildcards (*), negative array indexes, and bracket-notation keys with spaces.
