Live data from dYdX — a leading decentralised perpetual-futures exchange running on its own Cosmos appchain with a fully on-chain order book — served from its public indexer API as clean JSON, no cache. Get every perpetual market with its oracle price, 24h price change, 24h volume and trade count, open interest, next hourly funding rate (and the annualised rate) and margin requirements (sorted by volume); pull one market's full state by ticker; read the live order book for a market (best bid and ask, spread, mid price and the top depth levels); or list the recent fills for a market. Read live from dYdX, nothing cached. This is dYdX's own on-chain perps order-book, funding-rate and open-interest layer — distinct from centralised-exchange tickers, aggregate derivatives feeds and other DEX feeds: a separate decentralised perpetuals venue with its own order book.
