Switch with an agent
Paste this into Claude Code, Cursor, Codex, or any coding agent. It finds your Intrinio calls and ports them to Massive.
Find every place my project calls Intrinio. Switch those calls to the Massive REST API. Read https://massive.com/docs/llms.txt for endpoints and auth, and read the API key from the MASSIVE_API_KEY environment variable. Keep my function signatures and data shapes the same, and list anything Massive does not cover.
The ported code calls the REST API directly. The Massive MCP server is optional, for checking real responses while the agent works. Massive also publishes skills and plugins for coding agents.
