Guidelines

1. Use Bearer auth: Prefer Authorization: Bearer $MASSIVE_TOKEN; Massive also supports apiKey query auth, but headers keep keys out of URLs.
2. Ticker formats vary by asset class: Stocks use symbols like AAPL; forex commonly uses C:EURUSD; crypto commonly uses X:BTCUSD.
3. Plan access affects freshness and history: Free and paid plans differ by recency, history, and supported asset classes.
4. Paginate when needed: Many endpoints return next_url; fetch it with the same Authorization header.
5. Use the official docs for endpoint-specific plan limits: Massive shows plan access, recency, and history on each endpoint page.
