Mock HTTP Request Generator
Every HTTP client call, curl command, and fetch() call eventually becomes a raw request on the wire — a method and path, headers, and an optional body. Seeing that raw format demystifies debugging and makes it clear why the Host header is required, why POST bodies need a Content-Type, and why GET requests have no body. This tool generates a sample raw HTTP request with no inputs required. The output randomises the method (GET, POST, PUT, DELETE) and the path (/api/users, /api/orders/42, /api/login, /api/products?page=2). Every request includes the request line, Host, User-Agent (curl/8.4.0), Accept, and a random 24-character Bearer token in the Authorization header. POST and PUT requests add Content-Type: application/json, a Content-Length computed from the body, a blank separator line, and a small JSON body with a name and a random value field. Copy the output into documentation, a test fixture, or a learning exercise. Understanding this wire format makes tools like curl, Postman, and HTTP proxies far less opaque when you are debugging an API that is not behaving as expected.

FAQ
what does the generated http request include
A request line (METHOD PATH HTTP/1.1), then Host, User-Agent, Accept, and an Authorization: Bearer header with a random token. For POST and PUT, it also adds Content-Type: application/json, a Content-Length, a blank line separator, and a small JSON body with name and value fields.
why do get and delete requests have no body
By convention and the HTTP specification, GET and DELETE convey their intent entirely through the request line and headers — the URL identifies the resource and the method says what to do with it. POST and PUT need a body to carry the data being created or updated. The generated requests follow this convention.
why is the blank line between headers and body important
HTTP message format uses a blank line (CRLF after the last header) to signal the end of the headers and the start of the body. Parsers rely on this delimiter — a missing blank line means the parser cannot find the body, and an extra blank line in the headers terminates them early. The generated requests include this separator correctly.
can I send this request directly to a server
Not directly from this tool. The output is the raw text of an HTTP request for learning and documentation. To send a real request, use curl with the -X and -H flags, or a tool like httpie. The generated text gives you the exact headers and body to specify in those tools.
