Crypto summary: Get Funding Rate Data description: >- [OpenAPI JSON Spec](/docs/output/v1_crypto_funding-rate_get.json) **Feature Overview** Get funding rate data for a specific trading pair with required time range filtering. **Main Use Cases** - **Perpetual Futures Trading**: Monitor funding rates for perpetual futures contracts - **Trading Strategy**: Use funding rates as a market sentiment indicator - **Risk Management**: Monitor funding costs for positions - **Technical Analysis**: Analyze funding rate trends over time **Query Parameters & Logic** **Required Parameters:** - `symbol`: Trading pair symbol (e.g., BTCUSDT) - `exchange`: Exchange name (currently only supports `binance`) - `start_time`: Start timestamp (Unix seconds) - required - `end_time`: End timestamp (Unix seconds) - required, must be after start_time - `limit`: Maximum number of results to return (1-1000, required) **Validation Rules:** - Symbol is required and must be a valid trading pair - Exchange must be `binance` - start_time must be before end_time - Limit range: 1-1000, required **Response Data Structure** - `data` ([]FundingRateData): Array of funding rate data points - `count` (int32): Actual number of data points returned - `latest_time` (string): Timestamp of the most recent data point (Unix seconds as string) **FundingRateData fields:** - `symbol` (string): Trading pair symbol (e.g., "BTCUSDT") - `funding_rate` (string): Funding rate in string format - `timestamp` (string): Unix timestamp in seconds as string (e.g., "1763978100") **Usage Examples** 1. **Get funding rate data for specific time range**: `?symbol=BTCUSDT&exchange=binance&start_time=1761502255&end_time=1764094255&limit=100` 2. **Get maximum data points**: `?symbol=ETHUSDT&exchange=binance&start_time=1761502255&end_time=1764094255&limit=1000` **Important Notes** - All parameters are required - Results are ordered by timestamp in descending order (latest first) - Funding rate represents the periodic payment between long and short positions - Funding rates are settled by the exchange at fixed intervals (every 8 hours for Binance) - No interval parameter needed as settlement times are predetermined by the exchange parameters: - description: Crypto token symbol (e.g., BTC, ETH, SOL) in: query name: symbol required: true schema: type: string -
