How this service works
Web search built for AI agents. Search the live web, pull recent news, and read any page as clean markdown — pay per call, free tier to start.
Output
Returns the decoded JWT payload including all claims such as subject (sub), expiry (exp), issued-at (iat), and any custom claims embedded in the token, along with header information like algorithm and token type.
Example use cases
Example prompt
“Can you decode this JWT for me and show me what claims are inside: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ1c2VyXzEyMyIsImV4cCI6MTcwMDAwMDAwMH0.abc123”
Technical details
Endpoint
GEThttps://superhighway.walls.sh/jwt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly inspect or debug a JWT token's contents, extract claims for logic decisions, or validate token structure without needing a full auth library. Useful when a lightweight, pay-per-call decode is preferred over maintaining a local JWT library.
Side effects
- Invalid or malformed JWT string returns a parsing error
- Expired token may still be decoded but claims will show past expiry
- Missing token parameter returns a 400 bad request
- Completely random non-JWT string will fail to parse and return an error
