Gives Claude access to 100 API services through a unified marketplace with automatic billing. Instead of hardcoding integrations, your agent can discover and call services on demand: web search via Tavily, image generation through Together AI, code execution in E2B sandboxes, text-to-speech, email sending, and 87 free services covering everything from weather and Wikipedia to Pokemon data and NASA feeds. Runs on a credit system with $1 free on registration and micropayments from $0.01 to $0.05 per call. Includes semantic discovery so Claude can search for "web scraping API" and find the right service, then execute it atomically with automatic refunds if calls fail. Useful when you want Claude to have broad API access without predefining every integration.
