How this service works
444 endpoints across 9+ chains. Crypto, AI, Social, Finance, Weather, Tools. Pay per call in USDC via x402 with 4 facilitators: Dexter, Meridian, FluxA, GoPlausible.
Output
Returns the decoded JWT broken into its components: the header (algorithm, token type), the payload (all claims such as sub, iat, exp, email, roles, and any custom claims), and potentially the signature section — all in human-readable JSON format.
Example use cases
Inspect auth token claims
“I have this JWT from our auth system and I need to know what user ID, roles, and expiration date are encoded in it — can you decode it? Here's the token: eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VySWQiOiI0MiIsInJvbGUiOiJhZG1pbiIsImV4cCI6MTcwMDAwMDAwMH0.signature”
Debug expired session token
“My app keeps saying the session is invalid — can you decode this JWT token and tell me if it's expired and what the issued-at and expiration timestamps say? Token: eyJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE2MDAwMDAwMDAsImV4cCI6MTYwMDAwMzYwMH0.sig”
Extract email from ID token
“I got this OpenID Connect ID token back from a login flow and I just need to pull out the email address and subject claim from it — can you decode it? Here it is: eyJhbGciOiJSUzI1NiIsImtpZCI6ImFiYyJ9.eyJzdWIiOiJ1c2VyMTIzIiwiZW1haWwiOiJqb2huQGV4YW1wbGUuY29tIn0.signature”

POSThttps://omni-api-cyan.vercel.app/api/tools/jwt/decodeWhen to prefer
Choose this endpoint when you need a quick, pay-per-call JWT decode operation without setting up a local library, when running in an environment where JWT libraries aren't available, or when you want to inspect token contents as part of an automated agent workflow using x402 micropayments.
Side effects
- Malformed or invalid JWT string returns a parsing error
- Empty or missing query/input field returns a validation error
- Token with non-standard encoding may fail to decode
- Network or service timeout returns a 5xx error
- Payment failure via x402 prevents the call from completing
