What it returns

Every venue's perpetual funding for one coin: the current rate with the venue's settlement interval, and the rate summed over window (1, 7, 30 or 365 days). One row per venue and margin type — stablecoin-margined (USDT/USDC) markets first, then coin-margined (inverse) ones; no ranking is implied by the order. Rates are percent per that venue's own interval (1, 4, 8 or 24 hours), so two venues compare only after scaling by the interval, and a rate whose interval is null does not compare at all; the trailing-window sum already folds the settlements in and compares directly. symbol is the coin ticker (e.g. "BTC"), matched case-insensitively — not an instrument id, not a token mint or contract address, and not scoped to any of this API's chains. An unknown ticker answers 404.

Chains

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

A JSON response. Every field is always present; null means the value could not be established, never zero.

Response fields of One coin's perp funding rate on every venue, now and over a window
Field	Type	Description
`symbol`	string	The coin, spelled as it is listed (e.g. "BTC", "kPEPE").
`window`	string	The window `accumulatedPercent` covers.
`markets`	object[]	Stablecoin-margined markets first, then coin-margined; no ranking within either.
`markets[].venue`	string	The trading venue, e.g. "Binance".
`markets[].margin`	string	How the perpetual is margined: in a stablecoin (USDT/USDC), or in the coin itself (inverse).
`markets[].fundingRatePercent`	number \| null	Current funding rate, percent per `fundingIntervalHours`. Positive: longs pay shorts. null when the venue quotes none right now.
`markets[].fundingIntervalHours`	number \| null	The venue's funding settlement interval, hours. null when not stated for the venue — the current rate then does not compare across venues; use `accumulatedPercent`.
`markets[].accumulatedPercent`	number \| null	The funding rate summed over the trailing `window`, percent. Positive: longs paid shorts. null when no sum is available for the venue, and null on every row when the window figures are temporarily unavailable.
