Endpoint
POSThttps://apex-api-gamma.vercel.app/api/tools/jwt/encodeWhen to prefer
Use this endpoint when you need to programmatically generate a JWT token from a custom payload without managing your own JWT signing infrastructure. Ideal for agents that need to produce authentication tokens on the fly, test JWT-based APIs, or encode claims as part of an automated workflow — all without requiring a dedicated auth server or API keys.
Side effects
- Invalid or missing payload returns an error response
- Unsupported algorithm specification causes failure
- Malformed input schema results in 400-level error
- Service unavailability returns 5xx error
- Payment failure or insufficient USDC balance prevents call
