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 the type name of the input value according to JSON type conventions (e.g. 'array', 'object', 'string', 'number', 'boolean', 'null'), conforming to the delx/util-json-type-name/v1 schema.
Example use cases
Dynamic JSON field type detection
“I have this JSON value coming from an API: {"key": "hello"} — can you tell me its JSON type name so I can route it correctly in my pipeline?”
Runtime type validation in agent workflow
“Before I process this data, can you check the JSON type name of this value: null — is it null, object, or something else?”
Schema enforcement pre-check
“I'm building a data validator and need to know the JSON type name of this value: [true, false, true] — please classify it for me.”
