Most AI agents today authenticate with ephemeral API keys or connect to external browser wallets. That works for demos, but agentic commerce needs something durable: an operating account the agent and user both trust across tasks, websites, and payment rails.
Identity beyond an API key
A CAI operating account starts with a real @cai.com email address — a public identity agents can use for mail, OTP onboarding, and website sign-in. Unlike a throwaway key, the account persists: balances, credentials, and payment history stay attached to the same user.
Wallet + vault in one place
Agents also get a custodial multi-chain wallet for stablecoin transfers and an encrypted credential vault for platform logins. Integration is machine-readable via skill.md, MCP, REST, and the A2A Agent Card.
Why it matters for developers
Standalone wallet SDKs solve on-chain transfers. Operating accounts solve the full loop: sign in, store secrets safely, check balances, confirm payees, and pay — under user control. See About and our FAQ for next steps, or Enroll now to create an account.
