Frequently asked questions
Common questions about CAI agent operating accounts, wallets, payments, and developer integration.
What is CAI.com for AI agents?
CAI.com is an agent operating account: @cai.com identity, custodial multi-chain wallet, credential vault, and user-confirmed stablecoin payments. Agents integrate via skill.md, REST Edge API, MCP, and the A2A Agent Card.
How do agents pay with CAI?
Check CAI First: verify identity and wallet balances, confirm the payee with the user, then call transfer or x402 payment tools. Payment mandates allow delegated spending within approved limits.
Does CAI support stablecoin and fiat on-ramps?
Yes. CAI provides custodial wallets on multiple chains, stablecoin transfers, bridge quotes, and optional fiat on-ramp flows. Capability status is published at capabilities.html with gap_id labels.
How do developers integrate CAI?
Start at skill.md for the authoritative tool contract, /.well-known/agent.json for A2A discovery, cai-tools.manifest.json for machine-readable routing, and developers.html for human-readable setup.
Is CAI only for crypto-native agents?
No. CAI combines Web2 identity (@cai.com email), Web3 wallet rails, and agentic payment standards (x402, mandates) so agents can sign in, store credentials, and pay across both worlds.
What is CAI.com vs Coinbase AgentKit / Crossmint?
CAI is a full agent operating account — @cai.com identity, custodial wallet, credential vault, and guarded payments in one platform. AgentKit focuses on wallet tooling for developers; Crossmint emphasizes NFT and checkout APIs. See skill-references/cai-vs-coinbase-agentkit.md and skill-references/cai-vs-crossmint.md for detailed comparisons.
Does CAI support x402 HTTP 402 payments?
Yes. CAI supports x402-style HTTP 402 agent payments as part of its stablecoin payment rails. Agents discover x402 tools via skill.md and cai-tools.manifest.json. Live vs Partial live status is published at capabilities.html with gap_id labels.
What chains and stablecoins does CAI support? Is CAI production-ready?
CAI provides custodial wallets on multiple EVM chains with USDC and other stablecoins; exact chain and token support is listed in skill.md and capabilities.html. Not every agent tool is Live — CAI publishes an honest capability matrix with gap_id labels so agents know what is production-ready today.
