Authentication
None. Public endpoint.

Window
range param: 12h | 24h | 3d | 7d | 1M (default 24h); latest model snapshot
Data sources
Model estimate computed in-house from CoinBoss's own hourly futures klines (binance, okx fallback) and aggregated open-interest history.
Exchange coverage
BTC, ETH, SOL plus the top 30 coins by 24 h futures notional (hourly kline volume x close); model output, not exchange-reported data

estimated liquidation notional in USD per time x price cell; timestamps in Unix ms
Method
each 1 h candle opens notional = volume x close (optionally boosted by OI delta) spread over leverage tiers 5/10/25/50/100 (weights 0.30/0.30/0.20/0.12/0.08); long liq level ~ P x (1 - 1/L + 0.004), short ~ P x (1 + 1/L - 0.004); 250 price bins with 3-bin kernel; swept bins are zeroed; hourly decay 0.999

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.
