FAQ
Why does this page cover only crypto?
Because crypto is the category most backtests start from: Up/Down intervals at 5m, 15m and 4h, price thresholds, and event-linked markets. Prices, metrics, and order books are aligned in one pipeline at 250ms resolution. Sports is covered just as deeply and served from the same endpoints — add category=sports, or see the sports coverage page. Nothing about querying sports is a different product or a different key.
What resolution is the crypto archive?
250ms capture and query on every plan, including the free Starter tier.
Is there a free way to try the data?
Yes — sign up for Starter (no card) or download the free BTC 5-minute order book sample in CSV/JSON.
