Know where every market layer begins.

Basis connects to public market endpoints from Binance, Bybit, OKX and Hyperliquid. Coverage varies by venue and instrument. Binance is the primary source for exact public-trade reconstruction, one-second bars and completed intraday archives; other venues can provide spot or perpetual candle streams where supported.

Derivatives panes use public venue APIs and label the active source. Binance, Bybit, OKX and Hyperliquid expose different subsets of funding, open interest, positioning, taker flow and liquidations. A blank field can therefore mean the selected venue does not publish that measure—not that a neutral value was observed.

The options workspace reads public option instruments, quotes, open interest and trades from Deribit, OKX, Bybit and Binance on the server, and caches each read briefly so every visitor shares it. Units are converted per venue before anything is summed: coin-quoted premiums at the venue index, contract counts to coins. Implied volatility is never averaged across venues; merged views read volatility from one named reference venue.

Global crypto market overview data is requested from CoinGecko. Bitcoin network calendar context uses public mempool.space block and difficulty data. Crypto headlines are aggregated from publisher feeds including CoinDesk, Cointelegraph, The Block, Decrypt, Bitcoin Magazine, CryptoSlate, Bitcoinist and NewsBTC. Headlines remain the work of their publishers and should be opened at the source before a high-stakes decision.

Public APIs can rate-limit, pause, revise recent bars or differ across instruments. Network latency and venue maintenance can create temporary gaps. Calculated notional values may use the latest available mark when the venue supplies historical contracts but not historical notional. Basis surfaces provider, freshness and degradation signals where the interface supports them.

Provider names identify the source of public observations; they do not imply endorsement or partnership. Availability is subject to provider terms, regional access and endpoint changes. Basis may replace or disable a source when it cannot meet the product’s accuracy or reliability requirements.
