HTTP API client

Builds a request to your own API and shows its exact wire form: request line, headers, body length, basic auth and bearer token substitution. Header values are checked for hidden line breaks, the body gets a consistent content type, and the response is analysed locally: status class, headers, size, JSON parsing and notes about caching and security. The request leaves the device only after you give consent on this screen.

Fill in the fields, run the tool and review the result. Your input is not added to a public page. Use the learning mode for calculation details.
