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 a signed JWT string (typically in the format header.payload.signature) that can be used as a bearer token or credential in downstream authentication flows.
Example use cases
Generate auth token for API access
“I need to create a JWT token from this user payload: {"sub": "user_42", "email": "alice@example.com", "role": "editor"} so I can authenticate API requests — can you encode it for me?”
Sign session claims for a web app
“Encode these session claims into a signed JWT: {"sessionId": "sess_789", "userId": "u001", "iat": 1700000000, "exp": 1700086400} — I need it to secure my web app's session management.”
Create a bearer token for service-to-service auth
“I'm setting up service-to-service authentication and need a JWT bearer token encoded from this payload: {"service": "billing", "scope": "read:invoices", "exp": 1720000000} — can you generate that for me?”
Technical details
Endpoint
POSThttps://omni-api-cyan.vercel.app/api/tools/jwt/encodeWhen to prefer
Choose this endpoint when you need a simple, pay-per-call JWT encoding service without managing your own signing infrastructure. It is well-suited for agents or serverless workflows that occasionally need to mint tokens without a dedicated auth server. If you require asymmetric key signing (RS256/ES256) or fine-grained algorithm control, a dedicated auth provider may be preferable.
Side effects
- Invalid or malformed JSON payload results in encoding error
- Missing required 'query' field returns a 400-level error
- Expired or invalid signing key causes token generation failure
- Oversized payload may be rejected depending on token size limits
- Payment failure via x402 protocol returns 402 Payment Required
