The platform provides a free @cai.com email address and enables agents to interact with CAI's API through a single command installation. The agent API supports MCP-compatible hosts like OpenClaw, Hermes, Codex, and Cursor.", "body_md": "A custodial email, a stablecoin wallet, a credential vault, and an agent-ready API — all at one `@cai.com`\n\naddress.\n\nThis post walks through what CAI is, what you get when you sign up, and how to wire the agent side into any MCP-compatible host.\n\nA free `@cai.com`\n\nemail comes with four product surfaces, all under one account:\n\n`@cai.com`\n\n.`cai.com/capabilities.html`\n\n).`pay`\n\nand `full`\n\nscopes may require verification. The key is in the account dashboard.The signup at `cai.com/app`\n\nis four steps. About 2 minutes.\n\n`cai.com/app`\n\n. Pick \"Apply for `@cai.com`\n\nemail.\"At the end you have:\n\n`@cai.com`\n\nemail address.No card. The email is free.\n\nFor the technical reader, the agent side is the reason to look at CAI. The install is one command:\n\n```\nnpm i -g @cailab/mcp\n```\n\nThe package is the MCP server — a thin wrapper around the CAI HTTPS Edge API at `https://api.cai.com/functions/v1`\n\n. It drops into MCP-compatible hosts including OpenClaw, Hermes, Codex, and Cursor (see `cai.com/developers.html`\n\nfor the current host list). Once installed, the agent can call `GET /get-identity`\n\n, `POST /get-wallet-balances`\n\n, `POST /wallet-custodial-transfer`\n\n, and the rest of the CAI surface — without the user pasting a private key in chat.\n\nThe contract an agent reads first is `cai.com/skill.md`\n\n. It's the canonical source-of-truth for what CAI can do, written in a format agents parse. The companion artifact is the A2A Agent Card at `cai.com/.well-known/agent.json`\n\n— that's how agents discover CAI in agent-to-agent registries.\n\n**Comment below with:**\n\nEvery comment on this article gets read.
