How this service works

Bundled execution of the JWT toolkit workflow - Decode and verify a JWT in one pass - see the payload and check the signature. One x402 payment runs 3 underlying tools (jwt-decode, jwt-verify, jwt-sign); partial-success per step.

Output

Returns the decoded JWT header and payload claims plus a signature verification result, covering all three underlying steps (jwt-decode, jwt-verify, jwt-sign) with partial-success reporting per step so you know exactly which parts succeeded or failed.

Example use cases

Example prompt

“Decode this JWT and check whether its signature is valid: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c”

Endpoint

POSThttps://agent402.tools/api/skill/jwt-toolkit

When to prefer

Use this endpoint when you need both the decoded claims and signature verification in a single API call rather than calling separate decode and verify endpoints. Ideal for debugging tokens, validating incoming JWTs in automated workflows, or inspecting bearer tokens without setting up local JWT libraries.

Side effects

Malformed JWT string causes decode failure on first step
Missing or incorrect secret/public key causes signature verification to fail
Expired token may decode successfully but fail verification
Network or payment failure returns no result
Token with unsupported algorithm may not verify correctly
