Generated by create next app
Output
A signed JWT token that can be used as a bearer credential for subsequent authenticated requests to the x402-qr-api service. The token encodes authorization claims and has an expiry.
Example use cases
Authenticate before generating QR codes
“I need to get a JWT token from the x402 QR API — pay the micropayment fee and return the token so I can use it to generate QR codes.”
Automated token refresh for QR workflow
“My current JWT for the QR API has expired — can you pay the 0.001 USDC x402 fee again and fetch a fresh JWT so my QR generation pipeline keeps running?”
One-time QR API credential acquisition
“I want to try out the x402 QR API — pay the small USDC fee and get me the JWT credential I need to access it.”
Technical details
Endpoint
GEThttps://x402-qr-api.vercel.app/api/jwt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to obtain a JWT for accessing the x402-qr-api and are prepared to pay the 0.001 USDC x402 micropayment. Choose this over manual auth flows when you want a pay-per-use credential model with no long-term API key management.
Side effects
- Payment not attached or insufficient — 402 Payment Required response
- Invalid or expired x402 payment proof — authentication rejected
- Service unavailable on Vercel — 503 or timeout
- JWT signing failure server-side — 500 Internal Server Error
- Rate limiting if too many token requests in a short window
