Self-serve realtime market data is out of beta
Self-serve realtime access has left the public beta: Binance USDT-M, Binance Spot, Coinbase Spot, Kalshi, Polymarket and OKX, delivered at our London, Frankfurt, Ashburn, Ohio and Tokyo endpoints — bought by the UTC day, streamed over WebSocket with one API key.
The feed, the protocol, the endpoints and your API key stay exactly as they are. Days now sell at the list price: €49 per instrument-day or €99 per market-day (Kalshi and Polymarket by the market-day only, as whole markets).
Duration prices
Longer runs cost less per day: every day of a run of consecutive days of the same market or instrument sells at its duration price.
- 14+ days: −10 % — €89.10 per market-day, €44.10 per instrument-day
- 30+ days: −25 % — €74.25 per market-day, €36.75 per instrument-day
- 180+ days: −37 % — €62.37 per market-day, €30.87 per instrument-day
- 365+ days: −50 % — €49.50 per market-day, €24.50 per instrument-day
Every day bought during the beta keeps the price paid. No subscription — nothing renews; you buy the days you need.
Thank you
To everyone who built on the feed during the beta and told us where the self-serve path still had gaps: thank you.
