Most AI agents hit a wall when they need to interact with the real world: take a screenshot, look up a DNS record, scrape a webpage, or check a crypto price. Each capability requires a separate API, separate auth, separate error handling. I built an API gateway that bundles 40+ tools behind one authentication token. Here's how to use it.
