We built Agent Commerce Gateway around a simple idea: businesses shouldn’t have to rebuild their backend every time a new agent protocol appears. Today, MCP, A2A, ACP, UCP, x402, MPP and AP2 all approach discovery, authorization, payments and state differently. Integrating each one separately quickly becomes another project to build and maintain. ACG puts one commerce layer in front of an existing API. Agents can discover a capability, pay for it and receive the result, while the merchant keeps control of its backend, pricing, infrastructure and payment destination. If your business has an API, dataset, report, or digital capability that could be sold to AI agents, ACG gives you the layer to expose and monetize it. The project is open source and self-hostable, and new protocols can be added as adapters instead of forcing merchants to rebuild their integration. We’d love feedback from anyone building agent infrastructure, APIs, payments, data products or machine-to-machine commerce.
