How this service works
Request headers echo: exact JSON of what your HTTP client actually sends - debug auth headers, signatures, x402 payments and proxies in seconds
Output
A JSON object containing all HTTP headers present in the incoming request, with each header name as a key and its value as the corresponding string value — enabling exact inspection of authorization tokens, x402 payment fields, proxy-injected headers, and custom signature headers.
Example use cases
Debug failing x402 payment header
“My x402 micropayment is being rejected and I'm not sure if the payment header is formatted right — can you echo back what headers I'm actually sending so I can see the x402 fields?”
Verify proxy forwards auth header
“I want to make sure my reverse proxy is correctly forwarding my Authorization bearer token — can you show me the exact headers that arrive at the server?”
Inspect HMAC signature header
“I need to check that my HMAC signature is landing in the right header name and format before I go live — can you hit the headers-echo endpoint and show me everything the server receives?”
Technical details
Endpoint
GEThttps://money-reactor.makar52nn2016.workers.dev/api/headers-echo?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify exactly which HTTP headers your client, SDK, or proxy is sending — especially for debugging x402 payment headers, authorization tokens, HMAC signatures, or proxy-forwarded fields. It is the fastest way to get ground truth on what arrives at the server without setting up your own echo server.
Side effects
- Payment not included or invalid: 402 Payment Required response if x402 payment header is missing or malformed
- No headers to echo: empty or minimal JSON if client strips headers
- Proxy stripping: headers may be absent if an intermediary removes them before reaching the endpoint
- Rate limiting: possible 429 if called excessively
