How this service works
Resolve an RFC 6901 JSON Pointer (e.g. /items/0/name) against a JSON value. Returns the value or found:false.
Output
Returns the value found at the specified JSON Pointer path within the provided JSON, or an object with found:false if the pointer path does not exist in the JSON structure.
Example use cases
Example prompt
“I have a big JSON blob and I need to pull out the value at /order/items/2/price — can you resolve that RFC 6901 pointer against it and give me back the value?”
Technical details
Endpoint
POSThttps://agent402.tools/api/json-pointerWhen to prefer
Use this endpoint when you need a standards-compliant RFC 6901 JSON Pointer resolution on an arbitrary JSON value without writing custom traversal code. Ideal for agents that receive JSON payloads and need to extract specific fields by path without full JSON parsing logic.
Side effects
- Invalid RFC 6901 pointer syntax returns an error
- Pointer path not found in JSON returns found:false
- Malformed JSON input causes a parse error
- Empty or missing json/pointer fields cause a validation error
- Deeply nested pointer on a scalar value returns found:false
