Where they differ
End-of-day vs intraday
Tiingo is strongest at end-of-day data: 30+ years of daily prices for stocks, ETFs, and mutual funds, for $30/mo. Its production intraday feed is IEX alone, with a multi-venue API in beta. Massive has every US trade and quote from all exchanges, back to 2003.
Options and futures
Tiingo does not list either. Massive sells all of OPRA and CME Group futures, from $29/mo per market.
Who can see the data
Tiingo plans are internal use only. Showing data to people outside your company needs a separate redistribution license. Massive Business plans include display.

- If you use Tiingo for fundamentals, you can keep it and move intraday and options data to Massive.
Switch with an agent
Paste this into Claude Code, Cursor, Codex, or any coding agent. It finds your Tiingo calls and ports them to Massive.
Find every place my project calls Tiingo. 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.
