FastX402 Lab JSON Pointer Extractor

Use this endpoint when you need to extract exactly one value from a known path in a JSON document without writing custom parsing logic. It is ideal when working with large or complex API responses where you already know the RFC 6901 pointer path to the field you need. Prefer it over full JSON parsing tools when you only need a single field and want a lightweight, pay-per-call solution.

• Malformed JSON input returns an error or found:false
• Invalid RFC 6901 pointer syntax may return an error
• Pointer path that doesn't exist in the document returns found:false
• Empty JSON document with non-empty pointer returns found:false
• Deeply nested or very large JSON documents may time out
