AI agent marketplace
A platform where AI agents, or the people operating them, discover, price, and pay for capabilities such as data APIs or specialized tools from many independent providers through one identity.
An AI agent marketplace connects many independent providers of agent-usable capabilities, data APIs, tools, or services, with agents that need them, through one shared point of discovery and payment. Instead of an agent's operator vetting and integrating each provider separately, the marketplace standardizes discovery, pricing, and settlement, so adding the next capability is a search rather than an integration project. The term covers two related but distinct ideas worth telling apart: a marketplace of agents for hire, and a marketplace of things an agent buys. Proxygate is the second kind.
For a marketplace built around things an agent buys, the buyer being software rather than a person changes what matters. Discovery has to be programmatic (searchable by an agent, not just browsable by a human), pricing has to be visible before spending, and payment has to clear without a person approving each transaction. A marketplace that assumes a human signs up, provisions a key, and pays a subscription is not really built for this buyer, even if agents can technically use it.
Proxygate is a neutral AI agent marketplace for real-world data and API access. Vetted sellers list machine-callable APIs; an agent discovers listings (including as MCP tools, so it can be reached as an MCP marketplace from any MCP-compatible client), pays per request from one prepaid USDC balance, and gets a signed receipt for every call. The platform stays neutral between buyers and sellers and handles identity, metering, and settlement.

It is a platform where AI agents, or their operators, discover, price, and pay for capabilities such as data APIs or tools from many independent providers through one identity, instead of integrating and paying each provider separately.
No, though the term gets used for both. One kind of marketplace sells agents themselves as a service. The other, which Proxygate is, sells the capabilities an agent consumes, such as data APIs, to agents as the buyer.
Proxygate is reachable as one: every listing is exposed as MCP tools, so an MCP-compatible client can browse the catalog, price a listing, and pay for it directly. The same marketplace is also reachable via an SDK, a CLI, or plain REST for agents that are not MCP clients.
