Source Details
Polymarket
Polymarket is a prediction market platform where users trade outcome shares for real-world events. Prices are expressed as probabilities between 0 and 1, where 1.00 means the market is fully resolved to "Yes." Volume is denominated in USDC. Use the /v1/markets endpoint to discover available event slugs before querying candles or snapshots.
Kalshi
Kalshi is a regulated event contract exchange (CFTC-regulated). Prices represent the cost of a contract that pays out $1.00 on resolution, expressed as a decimal between 0 and 1. Order book data is available on Pro plans and above. Use the /v1/markets endpoint to list available contracts and their tickers.
Binance (Spot)
Binance spot data covers major trading pairs (e.g., BTCUSDT, ETHUSDT). Candle prices are in the quote currency (typically USDT). Volume is expressed in the base asset. Symbols follow Binance's standard format: base + quote with no separator (e.g., BTCUSDT, SOLUSDT).
Binance Futures
Binance USDT-margined perpetual futures. Funding rates are expressed as a decimal (e.g., 0.0001 = 0.01%). Open interest is denominated in the base asset. Liquidation data includes side, quantity, and price. Symbols match the futures format (e.g., BTCUSDT, ETHUSDT).
Chainlink
Chainlink oracle data represents on-chain price feed updates from Chainlink's decentralized oracle network. Prices are normalized to USD with 8 decimal places. Each data point corresponds to a round update or heartbeat event. Symbols use the base asset only (e.g., BTC, ETH).
Hyperliquid
Hyperliquid is a decentralized perpetual exchange. Data coverage mirrors Binance Futures: candles, funding rates, open interest, and liquidations. Funding rates are per-hour. Symbols use the base asset only (e.g., BTC, ETH, SOL).
