Proceeds

Proceeds lets you monetize any API by adding a programmable payment layer in front of your endpoints. With Proceeds, you can put a paywall in front of an existing API, define pricing for each endpoint, and accept payments through machine-payment standards such as x402, Machine Payments Protocol (MPP), and Circle Nanopayments. Proceeds runs as a proxy server between your API and the clients calling it, so you can start charging for access without rebuilding your backend. Use Proceeds to turn APIs, MCP tools, agent services, datasets, compute jobs, or digital resources into paid endpoints that can be accessed by humans, applications, and AI agents.

What Proceeds does

Proceeds wraps your API with payment enforcement. When a client requests a protected endpoint, Proceeds determines whether payment is required, returns the appropriate payment challenge, verifies the payment response, and forwards successful requests to your origin API. Your backend continues serving the resource; Proceeds handles the payment flow in front of it. You can use Proceeds to:

Add paywalls to existing API endpoints
Set pricing per endpoint or collection of endpoints
Support payment standards such as x402, MPP, and Circle Nanopayments
Accept programmatic payments from agents, applications, and automated workflows
Track revenue and payments across your protected APIs
Organize related endpoints into collections for easier management
