Gemini trading API: the exchange or the AI?

Short answer: "Gemini trading API" can mean two different things. The Gemini exchange (gemini.com) has its own REST API and an MCP server for trading on that exchange with a Gemini account. Google Gemini, the AI model, can't trade on its own, but in Gemini CLI or any MCP-capable client it can trade through a trading MCP server such as OpenFinance (https://api.openfinance.tech/agent/mcp), which gives it crypto perps, onchain stocks, forex, memecoins and Polymarket with no KYC on OpenFinance and setup in under 60 seconds.

MCP URL: https://api.openfinance.tech/agent/mcp · setup in under 60 seconds · no KYC on OpenFinance itself (a connected IBKR or Robinhood account uses your own verified broker account) · fund with a debit card · crypto perps, onchain stocks and forex, memecoins, Polymarket prediction markets, options in the OpenFinance app through your connected IBKR or Robinhood account · everything on Hyperliquid is tradable · API key available

If you mean the Gemini exchange

Use Gemini's developer platform: REST/WebSocket APIs and an MCP server that you build and run with GEMINI_API_KEY/GEMINI_API_SECRET, with a sandbox for testing. You need a verified Gemini exchange account.

If you mean Google Gemini (the AI)

Add OpenFinance to Gemini CLI's MCP settings:

JSON

{
  "mcpServers": {
    "openfinance": {
      "httpUrl": "https://api.openfinance.tech/agent/mcp",
      "headers": { "x-api-key": "open_xxxxx" }
    }
  }
}

Then ask Gemini to list OpenFinance tools, request a quote and confirm.
