Market Data Overview

Public, unauthenticated endpoints for Binance USDⓈ-M Futures market data plus a few helpers maintained by the platform.

Base URL

https://api.pipai.org

api.pipai.org exposes market-data endpoints through two distinct route families. Pick the one that fits the call:

/fapi/v1/* — transparent Binance mirror. nginx forwards the request verbatim to fapi.binance.com/fapi/v1/*. Path, query string, headers, signature, and response are passed through unchanged. Use this whenever Binance offers the endpoint directly — it's the lowest-overhead path.
/<gateway path> — FastAPI gateway. Used for endpoints that aren't a single 1-to-1 Binance call: filtered/sorted helpers (/ticker/24hr/active, /launchfutures, /delist), platform-shaped wrappers (/funding/rates*, /long-short/*), and Binance endpoints that live outside /fapi/v1/* (e.g. /futures/data/openInterestHist, /bapi/...).

Topic	Endpoint(s)	Route family	Page
Klines	`GET /fapi/v1/klines`	Binance mirror	Klines
24h ticker	`GET /fapi/v1/ticker/24hr`, `GET /ticker/24hr/active`	Mirror + gateway helper	Ticker
Order book depth	`GET /fapi/v1/depth`	Binance mirror	Depth
Exchange info	`GET /fapi/v1/exchangeInfo`	Binance mirror	Exchange Info
Premium index	`GET /fapi/v1/premiumIndex`	Binance mirror	Premium Index
Funding rates	`GET /fapi/v1/fundingRate`, `GET /funding/rates`, `GET /funding/rates/{symbol}`, `GET /funding/rates/{symbol}/history`	Mirror + gateway	Funding Rate
Open interest	`GET /fapi/v1/openInterest`	Binance mirror	Open Interest
Open interest history	`GET /openInterestHist`	FastAPI gateway	Open Interest History
Long/short ratios	`GET /topLongShortPositionRatio`, `GET /topLongShortAccountRatio`, `GET /long-short/position-ratio/{symbol}`, `GET /long-short/account-ratio/{symbol}`	FastAPI gateway	Long/Short Ratio
Futures launches	`GET /launchfutures`	FastAPI gateway	Launch Futures
Futures delistings	`GET /delist`	FastAPI gateway	Delist
Insurance fund	`GET /fapi/v1/insuranceBalance`	Binance mirror	Insurance Balance
Spot capital flow	`GET /spot/capital-flow`	FastAPI gateway	Spot Capital Flow

All endpoints are public. Per-IP rate limit applies (1000/min) on the FastAPI gateway routes; the Binance mirror additionally inherits Binance's per-IP weights.
Responses on the Binance mirror are byte-identical to Binance's response — string-encoded numbers, Unix-millisecond timestamps, and Binance's own field naming. Field reference: see Binance USDⓈ-M Futures API docs for the corresponding endpoint.
Query parameter casing varies by endpoint (mostly camelCase; the /funding/rates/{symbol}/history gateway endpoint uses snake_case start_time/end_time). Each page calls out its own casing.

No WebSocket streams. (The backend is REST-only.)
No public trade-tape endpoint. (/trades/history exists but is account-scoped and out of scope here.)
