Start L25

L25 roams a whole venue — pick which one (Polymarket prediction markets, Hyperliquid or Kalshi); each venue is its own subscription, so plans for other venues add up alongside this one. History before your 7-day lookback is bought as backfill, below or later from your plan page. Confirm the seat terms below; checkout happens on Stripe's hosted page.

this plan is for

Polymarket prediction markets · prediction markets + perps
Every prediction market on the venue — L1, L2, trades, candles, on-chain fills.Hyperliquid · hyperliquid
Every Hyperliquid perp, spot pair and HIP-3 market since January 2025 — top of book on every change, the 25-level order book on every change, and every trade, reconstructed from the chain's own order-event stream rather than sampled from a websocket.Kalshi · kalshi
Every Kalshi series from our own capture (from 27 September 2026): the 25-level book on every change, top of book, every trade and Kalshi's ticker, plus every Kalshi trade back to June 2021 as trades-only history.

Each venue is its own subscription: add another venue's plan whenever you like, monthly or yearly, and they add up.
