Are there any services that return information about the browser upon request?

Question

Browsers

For example, I enter the address of the service into the browser, and in response I receive information about my browser, user agent, any parameters and headers, passed parameters (get, post)? And it is desirable to receive the answer in a simple form, and not in the form of a loaded html page, since I plan to make requests with firefox, curl, php, wget, etc.
PS: I need this to masquerade as a real browser.
PS2: In general, such a service is not a big problem to write (with the help of Google), just maybe there are ready-made services, so as not to reinvent the next wheel. Thank you!

Answer 1

There are hundreds of such services, google "browser info". But for your task they are not needed, use the developer tools in the browser - see what headers are sent and forge them.
