How this service works
devutils-headers
Output
Returns a structured object containing all HTTP request headers received by the server for the GET request, including standard headers like User-Agent, Accept, Host, and any custom or forwarded headers present in the request.
Example use cases
Debugging proxy header forwarding
“I'm behind a reverse proxy and I want to check whether the X-Forwarded-For and host headers are being passed through correctly to the origin server — can you fetch my current HTTP headers so I can verify?”
Verifying client user-agent string
“Can you check what user-agent string my HTTP client is sending right now? I need to confirm it's being set correctly before I push this to production.”
Inspecting headers during API development
“I'm building an API integration and want to see all the headers my app is including in outbound GET requests — can you pull the full header list the server sees so I can debug any missing or malformed entries?”
Technical details
Endpoint
GEThttps://exchangerebel.com/toll/devutils/headers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to inspect or debug the exact HTTP headers a client or proxy is transmitting, particularly during development or integration testing. It is ideal for verifying header forwarding through proxies, checking user-agent strings, or confirming that custom headers are being sent as expected. Prefer this over manual tools when you need programmatic, agent-accessible header introspection as part of an automated workflow.
Side effects
- Missing or malformed 'input' object returns a validation error
- Unsupported HTTP method (non-GET) returns an error since only GET is allowed
- Payment failure or insufficient USDC balance results in 402 response
- Network timeouts or server-side errors may return 5xx responses
