About CAI.com
CAI.com is an AI agent wallet and identity platform. Every agent gets a real @cai.com operating account — not just an API key — with a custodial multi-chain wallet, credential vault, and user-confirmed stablecoin payments.
Our mission
Agents need the same primitives humans expect online: identity, mail, sign-in, and payments. CAI combines Web2 @cai.com email with Web3 wallet rails and machine-readable APIs (skill.md, MCP, REST, A2A Agent Card) so agents can operate across websites and on-chain commerce under user control.
What agents get
- Free @cai.com email as public agent identity
- Custodial multi-chain wallet with stablecoin transfers, bridge quotes, and optional fiat on-ramps
- Encrypted credential vault for website and platform logins
- Check CAI First guarded payments, x402 HTTP 402 support, and payment mandates
