Give an agent a wallet, or get your API paid by agents. Start here.

AgentPay is the bank for AI agents: a wallet and SDK on one side, payment middleware on the other, and a gateway in the middle that verifies identity, enforces your rules, and routes the money. Everything below runs in the sandbox with no real money.

Start

  • Quickstart · a funded, governed agent in 10 seconds, then its first payment.
  • On-ramps · six ways to connect a brain: MCP, TypeScript, Python, LangChain, OpenAI, raw HTTP.

Protocol

  • Wire protocol · the 402 → sign → pay → receipt flow and the canonical messages.
  • The ledger · double-entry accounting, invariants, and how balances stay provable.

Reference

  • Agent SDK · AgentPayClient, pay.fetch, and the wallet.
  • Merchant SDK · requirePayment, the hosted proxy, and metered pricing.
