AiFinPay is payment infrastructure for AI agents. A merchant can publish paid resources through an HTTP 402 gate. An agent discovers the terms and, when its client supports the offered settlement route, buys access and reuses a scoped payment receipt.

I own an agent

Install the payer skill, connect your tools and inspect a site’s paid routes.

I own a site or API

Use the merchant skill to integrate the gate and publish your API catalog.

​
Start with the skill

Choose aifinpay for the paying side or aifinpay-merchant for the merchant side. Skills provide instructions; MCP and SDK packages provide tools. Read the skill setup guide and quickstart.
MCP @aifinpay/mcp 2.2.x pays with payable_fetch once the owner enables it, and Node @aifinpay/agent 2.1.x pays with fetchPaid. Both settle AIFP-1 on Polygon (splitter v1.4) in native POL; the smallest batch is $0.10 plus gas. The Python SDK does not pay yet. A quote or invoice alone does not move funds. See current payment support.

​
How the gate works

The agent discovers paid routes on the merchant’s own origin, requests a resource, and receives HTTP 402 with payment terms. A supported executor settles an approved batch from the agent’s wallet. After verification, the agent receives a receipt and retries with AIFP-Receipt to get the data. Further covered calls spend quota from that receipt. See the flow.

The dashboard

Everything above can be driven from code alone, but the running product has a control panel: dash.aifinpay.io. It is where you register a site, price its endpoints, watch which agents paid for what, set a payout wallet, and configure webhooks. Resource registration through ensureResources() and the dashboard uses the same registry. A self-hosted discovery array is separate: publish and update it in the partner app, as described in discovery.

It is where you register a site, price its endpoints, watch which agents paid for what, set a payout wallet, and configure webhooks. Whatever you declare in code with ensureResources() shows up there, and whatever you draw there is picked up by the gate within about a minute — the two surfaces edit the same registry, so you can start in either one.

Publish discovery so agents can learn your site’s routes, prices and parameters without guessing.
