How this service works
Send an HTTP request to any URL from our servers and receive the full response — including the status code, all response headers, and the body content. Supports GET, POST, PUT, PATCH, DELETE, and HEAD. Automatically follows up to 3 redirects. Useful for testing endpoints, verifying servers are responding correctly, debugging redirect chains, or fetching raw data without needing a local setup.
Output
A JSON object containing the HTTP status code, response headers (as key-value pairs), the full response body as a string, the HTTP method used, the target URL, round-trip duration in milliseconds, any redirect chain followed (up to 3 hops), an error field if the request failed, and the API version.
Example use cases
Example prompt
“Can you send a GET request to https://api.example.com/health and tell me the status code, response headers, and body that come back?”
Technical details
Endpoint
POSThttps://curl-http-request.underscoredone.com/curlWhen to prefer
Use this endpoint when you need to make an arbitrary HTTP request to any URL from a neutral remote server without local tooling — especially for testing endpoint liveness, inspecting response headers, debugging redirect chains, or fetching raw response bodies. Prefer this over browser-based scrapers when you only need raw HTTP semantics rather than rendered HTML, and over local curl when you want a hosted, pay-per-call solution with structured JSON output.
Side effects
- Invalid or malformed URL returns an error in the error field
- Target server is unreachable or times out, resulting in a non-200 status or error string
- Redirect chain exceeds 3 hops and is truncated
- Payment not fulfilled results in 402 response before the request is proxied
- Target URL returns non-JSON body which is still captured as a raw string in body field
