How do I call a Stock quote API from an AI agent?
Connect your agent once: paste the message from superpowers.tools/docs into Claude, ChatGPT or Codex. Then ask in your own words, and your agent picks this provider and runs it. You pay only when a call works, and new accounts get $5 free. Developers can call POST /v1/run with "tool": "alphavantage.quote" or use the MCP server.
For developersAPI call and the shared input and output format
Call it with one API key: POST /v1/run with "tool": "alphavantage.quote", or through the MCP server. Every provider takes the same input and returns the same output, and failed calls are not charged.
