pay.agent

Get paid in crypto with one link. Venmo for the agentic web, on CoinPay.

Sign in with CoinPay, pick a name, and share pay.agent/you. People and agents pay you in USDC, BTC, ETH, SOL and more; it lands in your CoinPay wallet or your CoinPay business. pay.agent never holds funds.

• Web: https://pay.agent (Moshpit DNS) or https://pay.agent.pit.world
• API: POST /api/v1/users/:handle/payments {"amount_usd": 5, "coin": "usdc_sol"} → address + exact amount
• CLI / TUI: bunx @profullstack/payagent alice 5 usdc_sol, or bunx @profullstack/payagent
• MCP: claude mcp add payagent -- bunx @profullstack/payagent mcp

Onboarding is @profullstack/coinpay-onboard: one pass makes the CoinPay business, payout wallets and webhook. The same engine runs at every fleet site launch.
