How this service works
DDG agent-payable service request
Output
Returns a JSON object with an 'ok' boolean field indicating whether the submitted HTTP request body is valid and conforms to the expected output schema. A result of {ok: true} means the payload passed validation.
Example use cases
Pre-flight API payload check
“Before I send this JSON object to the orders API, can you validate it against the expected response format to make sure it's well-formed and will return ok: true?”
Form data submission validation
“I have a form-data body I'm about to PATCH to a user profile endpoint — can you check whether it's valid and properly structured before I submit it?”
Agent pipeline request verification
“My automated pipeline is generating JSON payloads for a PUT request — can you verify each one is valid JSON with the correct structure before it gets sent downstream?”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/json-validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call JSON/HTTP body validation service with no account setup, billed fractionally via x402 USDC micropayments. Ideal for AI agent pipelines that need to validate request payloads on-the-fly before forwarding them to downstream APIs, especially when you want a bounded, stateless validation artifact rather than raw provider account access.
Side effects
- Malformed or non-JSON body returns validation failure
- Missing required fields (input, output) causes a 400-level error
- Incorrect method enum value (not POST/PUT/PATCH) causes rejection
- Payment not settled via x402 results in 402 Payment Required response
- Body type mismatch (e.g. sending form-data declared as JSON) may cause parse failure
