Start in minutes
Sign up, pay by card or crypto, and your API key is issued immediately — no sales call, no onboarding queue.
For traders
Data you can build a strategy on
Built for people who write code against the market — individual traders, algo developers and small quant teams.
One API, every market
Crypto, FX, metals, indices and commodities behind a single key and one consistent schema.
Know when a market is really open
Every quote carries market_open and session_state, so your strategy never trades a stale, carried-forward price.
Backtest honestly
Minute bars back to 2017 and daily to 1983, with delisted instruments retained so your universe is not survivorship-biased.
Funding and swap rates
Carry costs for perpetuals and CFDs, which most feeds leave out entirely.
Predictable limits
Rate limits are explicit and returned in X-RateLimit headers, so you can pace your own requests.
