How this service works

Decode JWT claims quickly for auth debugging, routing, and token inspection.

Output

Returns the decoded JWT header (algorithm, token type), payload claims (sub, iss, iat, exp, and any custom claims), and metadata about the token structure — useful for auth debugging, routing decisions, and token inspection.

Example use cases

Example prompt

“Can you decode this JWT token and show me all its claims — I want to see the issuer, subject, expiry, and any other fields in the payload: eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c”

Endpoint

POSThttps://api.delx.ai/api/v1/x402/jwt-inspect

When to prefer

Use this endpoint when you need to quickly decode and inspect the claims inside a JWT — especially for debugging auth flows, extracting user identity fields for routing, or auditing token contents without needing to verify the signature cryptographically.

Side effects

Malformed or invalid JWT string returns a parse error
Expired tokens are decoded but flagged as expired
Missing token input returns a validation error
Non-JWT strings (e.g. opaque tokens) cannot be decoded
