nownumbermsServer time when the response was built.
coinstring—Coin symbol, upper case (for example BTC).
avg_8hnumber—Mean of 8h-normalised rates.
dataarray—Payload.
data[]object—Payload.
data[].exchangestring—Exchange id, lower case (for example `binance`).
data[].ratenumber—Funding rate of the current period as published by the exchange.
data[].next_funding_timenumber|nullmsNext settlement time.

Details

Authentication
None. Public endpoint.
Rate limit
1200 requests per minute per IP
Server cache
60s
Edge micro-cache
10s
Update frequency
every 60 s for most venues (written together with tickers; binance dedicated 60 s job); remaining funding jobs and coin-margined contracts every 5 min
Window
latest snapshot; funding rows within 4 h and only for contracts with a live ticker (1 h) or open interest (3 h)
Data sources
Current funding rates polled by in-house collectors from the public REST APIs of 24 perpetual venues (e.g. binance, okx, bybit, bitget, gate, hyperliquid).
Exchange coverage
24 venues; multiplier contracts folded into the base coin; tokenized-stock ticker collisions isolated
Units
rate = raw fraction per interval; rate_8h = fraction normalized to 8 h; apr_pct in percent
Method
one contract per exchange (largest open interest); rate_8h = rate x 8 / interval_hours; avg_8h = simple mean; oi_weighted_8h = SUM(rate_8h x oi_usd) / SUM(oi_usd); apr_pct = rate_8h x 3 x 365 x 100
Timestamps
Unix epoch milliseconds (UTC) unless the field description says otherwise

Errors

Failed calls share one shape on every endpoint. The full list is on the errors page. Errors and rate limits →

CodeHTTPMeaningWhat to do
INVALID_PARAM400A required parameter is missing or a value is not accepted. `param` names the parameter when it is known.Do not retry unchanged; fix the request.
UNAUTHORIZED401The `CB-API-KEY` header was sent but the key is unknown or revoked. Public data needs no key — drop the header or use a valid key.Do not retry unchanged.
FORBIDDEN403The route is not part of the public API (internal or account-only).Do not retry.
NOT_FOUND404Unknown route, or the requested coin / exchange / fund does not exist.Do not retry; check the path and identifiers against the catalog.
RATE_LIMITED429More requests than the per-minute limit. `Retry-After` gives the seconds to wait.Wait for `Retry-After`, then retry with backoff.
INTERNAL500Unexpected server error. The message is generic by design; quote `request_id` when reporting it.Retry once after a few seconds; report it with the request id if it persists.
UPSTREAM_FAILED503The data source behind this endpoint did not answer in time. No stale or substitute numbers are returned in its place.Retry with backoff; check the status page.
UNAVAILABLE501 / 503The dataset is temporarily not ready (cache warming) or the endpoint has no lawful public source yet.Retry later; the catalog marks endpoints that are unavailable by design.
REQUEST_FAILED200Some older endpoints answer HTTP 200 with `success: false`. Always check `success`, not only the HTTP status.Depends on the message; treat as a failed request.
