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 with a 'result' field containing: a boolean 'valid' flag, a 'header' object with the algorithm (alg), a 'payload' object with standard claims like sub and exp, and a 'claims' object with human-readable values like exp_iso (ISO 8601 expiry). Also includes a 'tool_name' field identifying the utility used.
Example use cases
Check if an access token is expired
“I have this JWT token from our auth system — can you decode it and tell me whether it's still valid and when exactly it expires? Token: eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1c2VyLTQ1NiIsImV4cCI6MTcwMDAwMDAwMH0.sig”
Extract subject and claims from agent token
“Can you parse this JWT and tell me what subject and payload claims are inside it? I need to know what agent ID is encoded and what algorithm was used.”
Debug a malformed or suspicious JWT
“This JWT token looks off to me — can you inspect it and tell me if it's structurally valid, what the header says, and what claims are in the payload? Here it is: eyJhbGciOiJub25lIn0.eyJzdWIiOiJoYWNrZXIifQ.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/jwt-inspect?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to quickly inspect or decode a JWT token to extract claims, check expiry, or verify structure without setting up a full auth library. Ideal for lightweight, pay-per-call token introspection in agentic pipelines where no signup or persistent credentials are needed. Prefer this over rolling your own JWT parsing when operating in a serverless or ephemeral agent context.
Side effects
- Malformed JWT string causes parsing failure
- Missing 'token' field in request body returns an error
- Expired token still returned but valid flag set to false
- Unsigned or none-algorithm tokens may parse but flagged accordingly
