AI agent integration
Connecting an AI agent to the external tools, data, and payment rails it needs to act, so it can fetch live information and transact instead of only generating text.
AI agent integration is the work of wiring an agent to the outside world: the tools it can invoke, the data it can read, and the rails it can pay on. A model on its own can only generate text from frozen training data. Integration is what lets it call a live API, read a current dataset, run an operation, and settle a payment, which is the difference between an assistant that describes an action and an agent that performs it.
Historically each integration was bespoke: a separate SDK, API key, auth flow, and billing relationship per provider, all wired in by hand before the agent could use any of it. Open standards have collapsed much of that. The Model Context Protocol gives agents a uniform way to connect to tools and data, and agentic payment protocols such as x402 give them a uniform way to pay, so adding a capability becomes a connection rather than a custom build.
Proxygate is built to make the data-and-payment side of integration a single step. An agent connects to one MCP gateway, searches a catalogue of machine-callable APIs, and calls any of them per request from one prepaid USDC balance, with provider keys injected server-side and a signed receipt returned for every call. Instead of integrating each provider separately, the agent integrates once and reaches the whole marketplace, paying only for the calls it makes.
