JSON Pointer API
Address values inside a JSON document by JSON Pointer (RFC 6901) — the /a/b/0 path syntax used by JSON Patch (RFC 6902), JSON Schema and OpenAPI $ref. The get endpoint resolves the value at a pointer (and tells you whether it exists); set writes a value at a pointer and returns the modified document (use - as the final array token to append); and list enumerates every pointer in a document, optionally only the leaf values. Token escaping (~0 for ~, ~1 for /) is handled for you. Perfect for surgically reading and patching deep JSON, building config and form tooling, and walking API responses. Pure local computation — no key, no third-party service, instant; up to 2 MB via POST. Live, nothing stored. 4 endpoints. Distinct from JSONPath querying, JSON diff/patch and dot-notation flattening.
