Massive vs EODHD
Massive is built on exchange feeds: real-time data from 100% of US stock volume, every trade back to 2003, plus options and futures. If you only need end-of-day prices or fundamentals for non-US stocks, EODHD covers that.

Where they differ
Where the data comes from
Massive takes data from exchange feeds and covers 100% of US stock volume in real time. EODHD says it does not use exchange feeds and aggregates more than 100 sources instead. Its US WebSocket streams trades and quotes from Cboe EDGX alone, capped at 50 symbols per token by default. Fine for a dashboard. Not for anything that depends on the national best bid and offer.
How calls are counted
EODHD plans allow 100,000 calls a day, weighted by endpoint: an end-of-day request costs 1, intraday 5, fundamentals 10, and bulk 100 or more. Massive paid plans have no call limit.
Outside the US
EODHD may be the better choice here: 70 exchanges, US end-of-day history back to 1962, and fundamentals for companies outside the US. Massive covers US markets, plus global forex and crypto, with SEC filings, insider trades, and economic data on every Stocks plan.

- EODHD tickers take an exchange suffix, such as AAPL.US. The .US is optional for US stocks.
- EODHD returns CSV unless you pass fmt=json. Massive returns JSON.
- Both APIs treat the start and end dates as inclusive.
Switch with an agent
Paste this into Claude Code, Cursor, Codex, or any coding agent. It finds your EODHD calls and ports them to Massive.
Find every place my project calls EODHD. 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.
