How this service works
JSON type name for a value. Call when you branch agent logic by runtime JSON type. Returns type string for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
A type name string indicating the JSON type of the submitted value — one of 'string', 'number', 'integer', 'boolean', 'array', 'object', or 'null'. No additional data is retained or returned; the result is advisory and local only.
Example use cases
Branching agent logic by value type
“I have a dynamic value coming from a user form — it could be a string, number, or array. Can you check what JSON type it is so I route it to the right handler?”
Validating pipeline input before processing
“Before I process this config field, can you tell me what JSON type it is? I need to confirm it's an object and not accidentally a string or null.”
Debugging unexpected API response shape
“I got back a value from an upstream API and I'm not sure if it's a number or a string — can you check the JSON type name for me?”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-type-nameWhen to prefer
Choose this endpoint when an AI agent needs a lightweight, stateless utility to classify a JSON value's type at runtime without shipping a local type-checking function or adding a dependency. Ideal for conditional branching, input validation preflight checks, or debugging dynamic payloads in pipelines where the type is ambiguous. At $0.001 USDC per call, it is cost-effective for occasional checks; for high-volume type classification, a local implementation may be preferred.
Side effects
- Missing or malformed 'value' field in the request body returns an error
- Payment failure or insufficient USDC balance returns a 402 response
- Malformed JSON body returns a parsing error
- Unexpected server error returns a 5xx response
