How this service works
jwt decode-only (no verification)
Output
Returns the decoded contents of the JWT token including the header (algorithm, token type) and payload (claims such as sub, iat, exp, role, etc.) as structured JSON. No signature verification is performed — the result reflects raw decoded data only.
Example use cases
Inspect token expiry before API call
“Can you decode this JWT and tell me when it expires? Here's the token: eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE3MDA1MDAwMDAsInN1YiI6InVzZXJfNDIifQ.signature — I just want the exp and sub fields, no signature check needed.”
Debug auth token in development
“I'm debugging my app and I need to see what claims are inside this token my server issued: eyJhbGciOiJIUzI1NiJ9.eyJyb2xlIjoiYWRtaW4iLCJ1c2VySWQiOiJhYmMxMjMifQ.sig — just decode it and show me the payload.”
Extract user role from incoming JWT
“Given this JWT token from an incoming request, can you decode it and tell me what role and user ID are encoded in the payload? Token: eyJhbGciOiJFUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VySWQiOiJ1c3JfOTkiLCJyb2xlIjoiZWRpdG9yIn0.sig”
Technical details
Endpoint
GEThttps://apex-edge-coral.vercel.app/api/v1/util/jwt-decode?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to inspect or extract claims from a JWT token quickly without caring about cryptographic validity — for example, during debugging, logging, or when you already trust the token's source and just need to read its payload. Do not use this when you need to verify that a JWT was actually signed by a trusted party; for that, use a proper JWT verification service that validates the signature against a known secret or public key.
Side effects
- Malformed or non-base64url token string returns an error
- Missing 'token' query parameter results in a bad request
- Token with fewer than three segments (not a valid JWT structure) may fail to parse
- Network timeout or service unavailability returns a 5xx error
