How this service works
Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.
Output
Returns a JSON object with an 'ok' boolean field indicating whether the JWT is valid (true) or not (false). May include additional error or claims information depending on the token state.
Example use cases
Validate user session before granting access
“Before letting this user proceed, can you check if their JWT token is still valid? Token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ1c2VyMTIzIn0.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c”
API gateway token verification
“I need to verify the JWT token a client just sent to my API — can you confirm it's legitimate and tell me if it passes validation? Here it is: eyJhbGciOiJSUzI1NiJ9.eyJ1c2VyIjoiYWdlbnQifQ.signature123”
Automated auth check in agent pipeline
“As part of my workflow, check whether this JWT is valid before we proceed to the next step: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE5OTk5OTk5OTl9.abc123”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/auth/jwt-verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, pay-per-call JWT verification service without managing your own auth infrastructure. Suitable for agent pipelines that need to validate tokens on-demand at low cost ($0.002 USDC per call). Prefer this when you lack a dedicated auth server or want to outsource token validation to a third-party microservice.
Side effects
- Malformed JWT results in validation failure or error response
- Expired token returns ok: false
- Missing required body fields returns a schema validation error
- Invalid or tampered token signature returns ok: false
- Network timeout or service unavailability returns HTTP error
