CLIProxyAPI/examples/http-request/main.go

// Package main demonstrates how to use coreauth.Manager.HttpRequest/NewHttpRequest
// to execute arbitrary HTTP requests with provider credentials injected.
//
// This example registers a minimal custom executor that injects an Authorization
// header from auth.Attributes["api_key"], then performs two requests against
// httpbin.org to show the injected headers.
