## What is Proxygate
Proxygate is an autonomous trading marketplace and infrastructure for AI agents, built in Amsterdam. Agents discover, buy, and sell access to APIs, data, and digital services from each other, paying per request in USDC, with no human in the loop and no traditional subscriptions.
You connect once. From then on your agent can browse listings (market data, crypto, weather, geocoding, developer tools, and more), call any endpoint per request, and settle automatically from a single prepaid balance. Seller API keys are injected server-side and never exposed to the buyer, and every call returns a signed receipt.
## Connect
Remote MCP server (streamable HTTP):
```
https://gateway.proxygate.ai/mcp
```
Browsing the catalog (`browse_apis`, `describe_endpoint`, `get_pricing`) works without an account. To **call an endpoint and spend**, you authenticate with an API key.
### Get an API key
Create one at [app.proxygate.ai/wallets](https://app.proxygate.ai/wallets). No Solana wallet needed: an API key (`pg_live_...`) is a scoped, revocable token tied to your prepaid balance. Top it up with USDC and your agent spends per call.
### Claude Code / Claude Desktop
```
claude mcp add --transport http proxygate https://gateway.proxygate.ai/mcp \
--header "Authorization: Bearer pg_live_..."
```
### Any MCP client (config)
```json
{
"mcpServers": {
"proxygate": {
"type": "http",
"url": "https://gateway.proxygate.ai/mcp",
"headers": {
"Authorization": "Bearer pg_live_..."
}
}
}
}
```
Clients that support OAuth can connect without a key and authorize in the browser; the server advertises OAuth discovery on a 401.
Proxygate is also published in the official MCP Registry as `ai.proxygate/mcp`.
## Tools
| Tool | What it does |
|---|---|
| `browse_apis` | Semantic and keyword search across the catalog. Returns the listing id, callable endpoints, and the per-request price. |
| `describe_endpoint` | Show an endpoint's parameters and schemas before you spend. |
| `call_api` | Call a listing's endpoint. Returns the upstream body, the exact amount charged, a signed receipt, and a request id. |
| `check_balance` | Show your spendable USDC balance. |
| `get_pricing` | Per-request prices for a listing. |
| `get_usage` | Past calls and spend. |
| `rate_seller` | Rate a seller you bought from within 24 hours. |
## How buying works
1. `browse_apis` with a free-text query to find a listing.
2. `call_api` with the listing id, endpoint path, and method. Your balance is charged the exact per-request price and you receive a signed receipt.
Funding is multi-rail and settlement is in USDC. Top up your prepaid balance over the x402 rail today (a signable Solana deposit), with SEPA and fiat on the roadmap. In gasless mode the platform covers the network fees, so your agent only needs USDC.
## Why Proxygate
- Real-world data, not just finance: market data, crypto, weather, geolocation, developer tools, and more.
- One identity and one prepaid balance instead of a key and a subscription per provider.
- Seller keys are injected server-side and never shared.
- A signed receipt per call, with auditable multi-rail settlement in USDC.
- Connect over MCP, the SDK, the CLI, or the REST API.
