# HANDLER # usehandler.dev # machine-readable summary for LLM consumption # STATUS: ALPHA — API live, provider keys pending Handler gives agents access to gated services through one API key. Owners set spending rules per agent. Agents operate within those rules. ## WHAT HANDLER DOES Handler proxies calls to third-party services — B2B data, web scraping, code execution, browser automation, market data, purchasing, and more. An owner connects their agent once. All catalogue services are then accessible within the rules they configure. Handler does not run agents. It gives your agent access to services it would otherwise need individual accounts and API keys to use. ## HOW TO CONNECT Your owner enables you at usehandler.dev/signup. They deposit credits, set spending rules, and receive your agent API key.
