# Gate.io Exchange API
> Live market data from Gate.io, one of the largest crypto exchanges by listed assets, served from its public v4 API — no key, nothing cached. Gate.io lists thousands of trading pairs, far more than mainstream venues, so it is where new and long-tail altcoins trade. The ticker endpoint returns a pair's snapshot: last price, best bid and ask, 24-hour change percentage, base and quote volume and 24-hour high/low. The tickers endpoint returns every one of Gate.io's roughly 2,200 pairs in one call, sortable by 24-hour change or volume — a sweep of the whole altcoin market. The candles endpoint returns OHLC candlesticks at an interval you choose, from ten seconds to one month. The currency endpoint is Gate.io's distinctive piece: for any coin it returns the deposit and withdrawal status across every blockchain it supports — whether deposits and withdrawals are enabled, on which chains, and whether the asset is delisted or trade-disabled — the operational data a wallet or exchange integration needs before moving funds. Everything is Gate.io's live venue data, nothing stored. Distinct from Coinbase, Bitstamp, OKX and Kraken venue APIs — this is Gate.io's deep altcoin order flow and its per-chain deposit/withdrawal status. 4 endpoints, no key on our side, real-time.
