agenticpay // pre-alpha

Get paid by AI agents.

Open-source payment infrastructure for the MCP ecosystem. Declare a price on any tool, agents pay in USDC over x402, settles on Solana in ~1.5 seconds. No Stripe. No accounts. No API keys.

GitHub → 5-min quickstart

Live demo

Real Claude Opus agent decides which paid tools to use, pays autonomously over x402, gets results, answers the user.

$ pnpm --filter @agenticpay/two-agent-demo agent

Task: Reverse 'agenticpay rocks' and tell me how many words are in
      'The quick brown fox jumps over the lazy dog'.

packages/facilitator — first open-source x402 facilitator. Verify + settle on Solana, pays SOL fees on behalf of the agent.
examples/two-agent-demo — Claude Opus agent paying for tool calls

Or just point at our hosted one

Skip self-hosting for testing. We run a free devnet facilitator:

Devnet only. Mainnet support and hosted commercial tier coming.

Why this exists

The current AI agent stack assumes humans hold the credit card. That breaks the moment agents act on their own initiative — calling APIs, hiring sub-agents, paying for compute. You can't OAuth your way through it.

Stablecoin micropayments over HTTP fix it. agenticpay packages the missing ergonomics for the MCP ecosystem specifically: any tool can declare a price, any agent can pay it, the whole pipeline including the facilitator that submits the on-chain settlement is open source and self-hostable.
