## API Overview

- `org.codelibs.curl.Curl`: entry point for HTTP methods (GET, POST, PUT, DELETE, HEAD, OPTIONS, CONNECT, TRACE).
- `org.codelibs.curl.CurlRequest`: builder for HTTP requests.
- `org.codelibs.curl.CurlResponse`: wrapper for HTTP responses.
- `org.codelibs.curl.CurlException`: unchecked exception for errors.
