Poloniex Exchange API

healthy 3,530 Subscribers

Live spot market data from Poloniex, one of the longest-running global crypto exchanges, served straight from its public v2 API with no key and nothing cached. The ticker endpoint returns a market's last price, open, 24-hour high and low, best bid and ask, the spread, 24-hour change, base and quote volume, trade count and mark price. The tickers endpoint returns every market for a quote currency ranked by 24-hour quote volume, so one call surfaces the most-traded pairs on the venue. The markets endpoint lists the tradable pairs with their price and quantity scales and minimum order size. The book endpoint returns live order-book depth — every bid and ask level with price and amount, plus the best bid/ask and spread. The trades endpoint returns the most recent public trades with price, size and taker side, so you can see the tape in real time. Everything is read live from Poloniex on each request, nothing stored. A distinct venue, separate from the other exchange feeds on the marketplace. Ideal for trading bots, price tickers, tape readers, arbitrage scanners and market dashboards. Live, no key. 5 spot endpoints. For candles or perpetuals use an OHLC or derivatives API.

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.
