Alpha Vantage

Alpha Vantage on xpay — Real-time financial data without the signup friction

Alpha Vantage is a widely-used provider of stock market data, forex rates, cryptocurrency prices, and company fundamentals. Developers reach for it when they need reliable, real-time financial quotes and historical data to power trading bots, portfolio dashboards, financial analysis agents, and market research tools. Traditionally, using Alpha Vantage meant signing up for an account, managing API keys, and paying subscription fees. On xpay, you call Alpha Vantage's tools directly through MCP without ever creating an Alpha Vantage account—just authenticate with your xpay key and pay per call.

What's available

• TOOL_LIST — Discover all available Alpha Vantage API tools with their names and descriptions. Use this to explore what's callable before diving into parameter schemas.
• TOOL_GET — Retrieve the complete parameter schema for one or more tools. Call this after TOOL_LIST to understand what arguments each tool accepts.
• TOOL_CALL — Execute a tool by name with your arguments. Always call TOOL_GET first to validate the schema, then invoke the tool with matching parameters.

When Alpha Vantage is the right tool

• Building a trading bot or portfolio tracker that needs real-time stock prices and historical OHLC data.
• Enriching financial analysis agents with live forex rates or cryptocurrency prices.
• Fetching company fundamentals (earnings, balance sheet, cash flow) for due diligence or research workflows.
• Creating market dashboards that display intraday or daily time-series data.
• Backtesting strategies with historical market data across multiple asset classes.

When to choose something else

• If you need ultra-low-latency tick data or microsecond-level precision, consider specialized market data providers like Bloomberg or Reuters.
• If your use case is purely educational or you're prototyping with mock data, free alternatives like Yahoo Finance or IEX Cloud may suffice.
• If you need options chains, derivatives pricing, or complex financial instruments beyond equities and forex, you may need a more specialized provider.
• If you're building a high-frequency trading system with millions of daily calls, direct Alpha Vantage subscription might offer volume discounts not available on xpay's per-call model.

Pricing snapshot

All Alpha Vantage tools on xpay are uniformly priced at $0.02 per call, with no subscription or minimum commitment. You pay only for what you use.

Quickstart

For Claude Code (recommended if you're using Alpha Vantage alone):

claude mcp add --transport http alpha-vantage "https://alpha-vantage.mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"

Replace YOUR_XPAY_KEY with your xpay API key (get one free at https://xpay.tools after email or Google signup).

Once connected, your agent can call Alpha Vantage tools by their native names. For example, ask Claude to "use TOOL_LIST to see what tools are available, then call TOOL_GET to fetch the schema for the stock quote tool."

For Cursor, Windsurf, Cline, or VS Code (Copilot):

Add this entry to your mcp.json configuration file:

{
  "mcpServers": {
    "alpha-vantage": {
      "url": "https://alpha-vantage.mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"
    }
  }
}

Your editor will then expose Alpha Vantage's tools to the AI assistant.

Unified endpoint (all xpay providers in one connection):

If you want to access multiple xpay providers (e.g., Alpha Vantage + Tavily + Apollo) from a single MCP connection, use:

claude mcp add --transport http xpay "https://mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"

With the unified endpoint, you'll have meta-tools like xpay_discover() to search across all providers and xpay_run() to invoke tools by their full path (e.g., alpha-vantage/TOOL_CALL).

Why route Alpha Vantage through xpay?

• No Alpha Vantage signup. xpay holds the upstream credentials. You authenticate once with your xpay key and gain instant access to Alpha Vantage's full API.
• Pay per call, not per month. No subscription tiers or minimum commitments. A single stock quote lookup costs $0.02; use it sparingly or heavily—you only pay for what you call.
• MCP-native integration. Alpha Vantage tools are exposed as standard MCP resources, so Claude, Cursor, and other MCP-compatible agents can discover and invoke them without custom wrappers or SDK imports.
• Unified billing across providers. If you also use Tavily, Apollo, or other xpay-wrapped APIs, all calls bill to one xpay account with a single invoice.
• Instant provisioning. Get started in seconds—no waiting for API key approvals or account verification from Alpha Vantage.
