Free-tier rate limit
Most "free" stock data APIs cap you at a handful of requests per day or hide the good stuff behind a paywall. StashGamma's free tier is generous on purpose — 300 requests/hour, 800/day, 4,000/week — enough to actually build and run something against, not just kick the tires. One endpoint, one dataset, no upsell wall in the middle of your integration.
Go to Profile → Developer API and click "Get free key".
Call GET /api/dataapi/v1/eod/QQQ with your key — see the quickstart guide for full code examples.
