What it returns

A cross-venue spot ranking: every row is one coin aggregated across the centralized spot venues covered, ordered by 24h volume descending (coins with no 24h volume last). The ranking is taken among the 200 largest coins by market capitalisation, so a smaller coin having an unusually heavy day does not appear even when it out-trades the coins listed. Each row carries its price and market cap in USD and, for the last 1h, 4h, 12h, 24h and 1w, its price change, volume split into taker buys and sells, net flow (buys minus sells) and volume change. No chain and no token subject in the request: a symbol here is a coin ticker (e.g. "BTC"), never a token mint or contract address on any of this API's chains. The major dollar stablecoins are not ranked.

Chains

This endpoint is not tied to a chain: it takes no chain in its request.
