That one website that tests an API without installing anything

Why it's the pick

Hoppscotch is a Postman-style API client in a browser tab: build requests with headers, auth and a body, and test REST, GraphQL and WebSocket APIs. It's free and open source with no account needed (signing in only syncs your collections), but some servers block browser requests, so you may need its browser extension or proxy.
