The CeFi Funding Rate endpoint lets you fetch the latest funding rate for a given symbol across supported exchanges. By default, it returns results from multiple CeFi venues so you can compare rates quickly. You can also specify one or more exchanges to narrow the response.

​
What this endpoint does

With this API, you can:
  • Fetch the latest CeFi funding rate for a given symbol
  • Return rates from all supported exchanges by default if exchange is not provided
  • Filter to one or multiple exchanges using a comma-separated list

Walkthrough to Get CeFi Funding Rate

​
1. Prepare your query

The CeFi Funding Rate endpoint requires one parameter:
ParameterDescription
symbolThe trading symbol (example: BTC, ETH)
Optional parameters you can use:
  • quote: Optional quote currency (example: USDT, USDC)
  • exchange: Optional exchanges, comma-separated (example: deribit,binance,okx,lighter)
Tip: If you do not provide exchange, the endpoint returns rates across all supported exchanges by default.

​
2. Find a symbol to test

To test quickly, you can use a major symbol:
  • Use BTC or ETH as your symbol
If you want a venue-specific contract format:
  • Add quote=USDT (common for many perp venues)
  • Add exchange=binance (or any supported venue) to narrow results
This symbol is used as the symbol parameter.

​
3. Fill the API form

Enter the symbol, set exchange and quote if needed, then click Send.

​
Reviewing the response

The response returns a queryDetails object plus one object per exchange:
  • queryDetails: Echoes what you queried, like symbol, quote, and exchange selection
  • binanceFundingRate / bybitFundingRate / okxFundingRate / deribitFundingRate: Exchange-specific funding rate objects when available
  • hyperliquidFundingRate / gateFundingRate / lighterFundingRate: Additional venue objects when available depending on your query
Important interpretation notes:
  • If you do not provide exchange, the endpoint returns rates across all supported exchanges by default.
  • For Gate.io, contracts use a USDT settle format like SYMBOL_USDT.
  • For Lighter, a positive rate means longs pay shorts, and a negative rate means shorts pay longs.
  • For Hyperliquid DEX (HIP3) funding, you must prefix the symbol with dex: (example: dex:BTC).
