Authentication
None. Public endpoint.
Rate limit
1200 requests per minute per IP
Server cache
30s
Edge micro-cache
10s
Update frequency
every 60 s for most venues (written together with tickers; binance top-50 and okx dedicated 60 s jobs); full binance / bingx / aster / gate / htx sweeps every 5 min; coin-margined / USDC / dated contracts every 120 s (promoted to the shared table every 5 min); cme once per trading day (04:10 UTC); 24 h baseline from the hourly archive
Window
latest snapshot; 24 h change vs the hourly bucket nearest to now - 24 h
Data sources
Open interest polled by in-house collectors from the public REST APIs of 22 derivatives venues (e.g. binance, okx, bybit, gate, bitget, hyperliquid) plus CME's official daily volume/open-interest report.
Exchange coverage
23 sources with fresh rows (22 venues + cme); all contract types (USDT / USDC / USD linear, coin-margined inverse, perpetual and dated); bybit and gate report double-sided open interest as disclosed by the venue; rows older than 3 h (cme: 120 h) are excluded
Pagination
limit (default 100, max 500)
Sorting
total_usd desc
Units
open interest in USD notional per exchange; change_24h_pct in percent; price in USD
Method
total_usd = SUM(oi_usd) over all fresh contracts of the coin (multiplier contracts such as 1000PEPE folded); change_24h_pct = (cur - prev) / prev x 100 using only exchanges present in both snapshots; contracts whose archived value is frozen for 3 consecutive hours are excluded from both sides
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.
