Agentpay
Adds programmable payment rails to Claude via the CKB Fiber Network, a Lightning-compatible L2. Exposes eight tools: check balances, send payments through Fiber invoices, create invoices to receive funds, pay other agents directly, and manage hold invoices for escrow flows where funds lock until service delivery. The hold invoice pattern is the hook here: agent A locks payment, agent B delivers the work, funds release atomically or refund on timeout. Useful when you want Claude to coordinate paid API calls between agents or handle micropayments without gas fees. Requires a Fiber RPC endpoint to settle transactions on CKB.
