Query Parameters

symbol

string

Filter by base asset symbol (e.g., BTC, ETH, SOL). Case-insensitive. Omit to get all symbols (paginated).

limit

integer

default:"50"

Maximum number of symbols to return in the all-symbols response. Range: 1–500.

offset

integer

default:"0"

Number of symbols to skip for pagination.

sort

string

default:"rate"

Sort order for all-symbols response. Options:

rate — Sort by average funding rate (descending by absolute value)
exchanges — Sort by number of reporting exchanges (descending)

detail

string

default:"summary"

Detail level for all-symbols response. Options:

summary — Returns average and exchange_count per symbol (default)
full — Returns full per-exchange breakdown for every symbol

integer

Number of exchanges currently reporting a funding rate for this symbol.

exchanges

object

Per-exchange breakdown. Only present when detail=full. Same structure as single-symbol exchanges.

data.total

integer

data.limit

integer

The limit value used for this response.

data.offset

integer

The offset value used for this response.

}

Single-Symbol Response Fields

data.symbol

string

The requested symbol.

data.average

number

Mean funding rate across all reporting exchanges (8h normalized).

data.exchanges

object

Per-exchange funding rate breakdown.

Show Exchange Entry

rate

number

Current funding rate as a decimal. Positive = longs pay shorts. Negative = shorts pay longs. Already normalized to 8h for all exchanges.

next_funding

string | null

ISO 8601 timestamp of the next funding event. Not all exchanges provide this.

updated_at

integer

Unix timestamp (milliseconds) when this rate was last fetched from the exchange.

Interpretation Guide

Rate	Meaning	Signal
> +0.03%	Extremely bullish positioning	Bearish contrarian
+0.01% to +0.03%	Moderately long-biased	Neutral
-0.01% to +0.01%	Balanced / Neutral	—
-0.01% to -0.03%	Moderately short-biased	Neutral
< -0.03%	Extremely bearish positioning	Bullish contrarian (squeeze risk)

Extreme funding rates (±0.3%+) are strongly mean-reverting within 4-24 hours. Combine with open interest and long/short ratio for highest conviction signals.
