Bitfinex Exchange API

healthy 4,069 Subscribers

Live market data from Bitfinex, one of the longest-running crypto exchanges, served straight from its public v2 API — no key, nothing cached. Bitfinex is best known for two things this exposes as clean JSON: deep spot order books, and a peer-to-peer funding (margin-lending) market that few APIs surface. The ticker endpoint returns a trading pair's snapshot: best bid and ask, last price, 24-hour change and percentage, volume, high and low — BTC/USD near $63,000. The funding endpoint returns a currency's lending market: the Flash Return Rate, the best bid and ask lending rates with their loan periods, and the daily rate annualised to an APR — so you can see what lending US dollars or BTC on Bitfinex pays right now, around 14% APR for USD. The tickers endpoint returns the whole exchange in one call, either every trading pair or every funding currency. The trades endpoint returns the live trade tape — the most recent executed trades with price, amount, side and time. Everything is Bitfinex's live venue data, nothing stored. This is the Bitfinex price, funding-rate and tape layer for any trading, lending, charting or market-data app. Distinct from Coinbase, Binance and Kraken venue APIs and from aggregated feeds — this is Bitfinex's own order book, its margin-funding rates and tape. 4 endpoints, no key on our side, real-time.
