FAQs

Frequently asked questions

Is Kwery free?

Yes. Our Free plan is $0 forever and includes 150K API credits per month, full order book depth, historical timestamp queries, and access to Polymarket, Kalshi, Binance Spot & Futures, Chainlink, and Hyperliquid for BTC, ETH, SOL, and XRP. You get 14 days of candles/snapshots (7 days for funding/OI/trades, 1 day for liquidations) and intervals 15m, 1h, 4h, 24h. Pro ($29/mo) and Business ($79/mo) unlock 6 months or full history, higher rate limits, and more intervals.

What markets are covered?

We cover Polymarket (Up/Down binary markets for BTC, ETH, SOL, XRP), Kalshi (event markets for BTC, ETH, SOL), Binance spot and perpetual futures (BTC, ETH, SOL, XRP) plus the Binance force-order liquidation stream, Chainlink on-chain reference prices (BTC, ETH, SOL, XRP on Polygon), and Hyperliquid perpetuals (BTC, ETH, SOL, XRP). Each source has 5m, 15m, 1h, 4h, and 24h (and 1s ticker for Binance where applicable).

Where do you get your data from?

We ingest directly from each venue’s public APIs and data streams: Polymarket and Kalshi for prediction markets, Binance for spot, perpetuals, and the @forceOrder liquidation stream, Chainlink aggregators on Polygon for on-chain reference prices, and Hyperliquid for perp order books and funding. We normalize everything into a single schema (OHLCV, order book, funding, OI, etc.) and serve it via our REST API.

How often are snapshots taken?

We store data at multiple time intervals: 5m, 15m, 1h, 4h, and 24h (and 1d for Binance). For Binance we also capture a 1s ticker (best bid/ask, last price). Order book snapshots are captured at sub-second granularity so you can reconstruct market state at any timestamp. History depth depends on your plan—Basic has a limited lookback (e.g. last 50 candles for 5m/15m); Pro and Business offer much deeper or unlimited history.

Is the data historical or ongoing?

Both. We continuously ingest live data from each venue (order books, trades, funding, OI, liquidations, oracle updates) and store it. You can query historical snapshots for backtesting and replay (e.g. “order book at timestamp X”) and use the same API for ongoing data—the same normalized endpoints serve past and present data.

How do I access the data?

All plans include REST API access. Authenticate with your API key (X-API-Key header or api_key query param) and call our endpoints for markets, snapshots, candles, funding, liquidations, and more. Free: 15 req/min, 600 req/hr; Pro: 50 req/min, 3K req/hr; Business: 150 req/min, 9K req/hr. See the docs for full details.

Can I upgrade or change my plan later?

Yes. You can upgrade from Free to Pro or Business anytime from the dashboard. Pro is $29/mo (or $23/mo billed annually) and Business is $79/mo (or $63/mo billed annually). For Enterprise and custom needs, contact us and we’ll tailor a plan to your requirements.
