Zero is best understood as a missing capability layer for AI coding agents. Agents are good at reasoning but stop cold when a task needs an external capability they were never given — generating a video, printing and mailing a letter, registering a domain, deploying a site, sending email, executing code. Zero's premise is that instead of the user going off to find an API key, the agent should discover and call a service itself.
Installation is deliberately light. You choose your assistant — Claude Code, Claude on web or mobile, Codex, Gemini CLI, OpenClaw — paste a single setup prompt, and Zero is installed and enabled. From then on the agent searches Zero's catalogue of hundreds of thousands of listed services whenever it needs something it can't do alone, and calls the best match per use rather than adopting a fixed integration.
Monetisation is service-by-service rather than subscription. The tool is free to set up and you receive $5 in starting credit; many services are free and paid ones are typically priced in cents per call. You fund a wallet you alone control, the price is visible before execution, and Zero adds no markup and does not custody funds. Your agent talks directly to providers, so Zero never reads the contents of your requests. Owner ZeroClick also lists x402 and MPP API surfaces plus an MCP server, and welcomes third-party providers through its Get Listed programme.
