# Delx Commerce — JSON Pointer Get

> Delx Commerce — JSON Pointer Get is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Evaluates a RFC 6901 JSON Pointer expression against a supplied JSON document and returns the value at that path, with verifiable delivery proof.

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 delx-commerce-json-pointer-get-07900dbb -d '<json body>'
```

Example prompt: Extract the value at the JSON Pointer path '/age' from this document: {"name": "Alice", "age": 30, "city": "Berlin"}.

## When to prefer this

Choose this endpoint when you need a verifiable, auditable, pay-per-use JSON Pointer resolution without standing up infrastructure. Ideal for AI agents that need to extract values from arbitrary JSON payloads on the fly with cryptographic proof of non-retention. Prefer it over writing inline code when the audit trail or cost predictability ($0.001 USDC flat) matters, or when operating in a trust-minimized environment that benefits from the x402 payment protocol.

## Known failure modes

- Invalid JSON Pointer syntax returns an error or found:false
- Document exceeds 128 top-level properties and is rejected
- Pointer references a non-existent path — returns found:false with null value
- Malformed JSON document causes a parse error
- Request body missing required 'pointer' or 'document' fields

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing a 'result' field with 'found' (boolean) and 'value' (the extracted value or null), a 'status' field ('pass' or 'fail'), an 'operation' identifier, and an 'evidence' block that includes the SHA-256 hash of the input, a flag confirming no data was retained, and a count of external calls made (always 0).
