# Delx JSON Path Pick

> Delx JSON Path Pick is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Extracts a value from a nested JSON object using a dotted path expression, returning the value, whether it was found, and the resolved path.

## 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 delx-json-path-pick-791c65cd -d '<json body>'
```

Example prompt: Can you pull out the value at the path 'user.address.city' from this JSON object: {"user":{"address":{"city":"Denver","zip":"80201"}}}?

## When to prefer this

Use this endpoint when your agent needs to extract a specific nested field from a JSON object using dot notation and you don't want to ship or depend on a full JSONPath engine. It's ideal for lightweight, single-field extraction from known JSON structures — particularly useful in agent pipelines where you're processing structured API responses or configuration blobs and just need one value without extra dependencies. Not suited for bulk extractions, array queries, or wildcard traversals.

## Known failure modes

- Path not found in object — returns found: false with a null or absent value
- Malformed dotted path string — may return an error or found: false
- Input object is null or not a valid JSON object — likely returns an error
- Path references an array index rather than a named key — behavior may be undefined
- Deep nesting beyond supported depth — may not resolve correctly

## How this service works

Pick a dotted path from a JSON object. Call when you extract nested agent fields without a full JSONPath engine. Returns value, found, path for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

## Output

Returns a JSON object containing the extracted value at the specified dotted path, a boolean 'found' flag indicating whether the path existed in the object, and the resolved path string that was traversed.
