Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-pointer-extract-06e71c92 -d '<json body>'
```

Example prompt: From this JSON blob {"user":{"name":"Ada","id":7}}, extract the values at paths /user/name and /user/id and tell me what you find.

## When to prefer this

Choose this endpoint when you need to extract one or more specific fields from a JSON document using standard RFC 6901 JSON Pointer syntax, especially when multiple paths must be resolved in a single call. Prefer it over writing inline parsing code when operating inside an autonomous agent pipeline that needs reliable, structured extraction with explicit found/not-found signals per path.

## Known failure modes

- Path not found returns found:false with no value for that path
- Malformed JSON Pointer syntax may cause path resolution errors
- Invalid or non-JSON input value causes extraction failure
- Empty paths array returns empty results with found_count 0
- Payment failure (HTTP 402) if USDC balance is insufficient

## How this service works

Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.

## Output

Returns a JSON object with ok:true, mode 'json_pointer_extract', a results array where each element has the requested path, a boolean 'found' flag, and the resolved value (if found), plus a total found_count integer.
