OKX Exchange API

healthy 3,682 Subscribers

Live market data from OKX, one of the largest crypto exchanges, across both spot and perpetual markets, served straight from its public v5 API — no key, nothing cached. The ticker endpoint returns any instrument's snapshot — last price, best bid and ask, 24-hour open/high/low, volume and the 24-hour percentage change — for a spot pair like BTC-USDT or a perpetual swap like BTC-USDT-SWAP. The tickers endpoint returns every instrument of a type (spot, swap or futures) in one call, sortable by 24-hour change or volume. The candles endpoint returns OHLC candles at a bar you choose, from one minute to one month. The funding endpoint returns the funding rate of any perpetual swap — the periodic payment between longs and shorts — with the rate annualised to an APR and the next funding time, the signal perpetual-futures traders watch. Everything is OKX's live venue data, nothing stored. This is the OKX price, perpetual-funding and candle layer for any trading, charting, derivatives or market-data app. Distinct from Coinbase, Bitstamp, Binance and Kraken venue APIs and from aggregated feeds — this is OKX's own spot and perpetual order flow and its per-contract funding rates. 4 endpoints, no key on our side, real-time.

WEMIX API — oanor API marketplace

WEMIX API

Live EVM on-chain data for WEMIX (chain id 1111) — the gaming-focused public Layer-1 built by Wemade, whose native token is WEMIX — served directly from public EVM JSON-RPC nodes with multi-node failover. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the WEMIX balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole WEMIX with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and game-economy analytics across the WEMIX ecosystem. Live keyless upstream. 5 endpoints.
