Generated by create next app
Output
Returns a JSON object or plain response containing all HTTP request headers as key-value pairs, including standard headers like Host, User-Agent, Accept, Authorization, and any custom headers such as x402 payment tokens that were sent with the request.
Example use cases
Debug forwarded headers in proxy chain
“I'm routing requests through a proxy and want to confirm which headers are actually making it to the server — can you call the headers endpoint and show me everything the server received?”
Verify x402 payment header presence
“I just set up x402 micropayment headers in my client — can you hit the headers endpoint and confirm that the payment header is showing up correctly on the server side?”
Inspect user-agent and client metadata
“Can you fetch the headers endpoint and tell me what user-agent and other client metadata the server is receiving from this request?”
Technical details
Endpoint
GEThttps://x402-qr-api.vercel.app/api/headers?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to inspect or debug the raw HTTP headers arriving at the x402-qr-api server, particularly when troubleshooting x402 payment header propagation, verifying proxy forwarding behavior, or confirming what metadata a Next.js Vercel function receives. Not suitable for general header inspection of arbitrary servers.
Side effects
- 402 Payment Required if valid x402 payment is not included
- 400 Bad Request if the request is malformed
- 500 Internal Server Error if the Next.js function fails
- Empty or partial headers if proxy strips certain fields before reaching the server
