Every Polymarket stream
13 typed data rooms and 20+ pre-aggregated alerts covering every signal on Polymarket. One API key, two purpose-built sockets, shared client patterns.
Live, not polled
Data pushes the moment it lands on-chain or crosses a threshold. No polling loops, no cache staleness, no reconnect bookkeeping.
Typed & resilient SDK
Per-room typed filters and payloads. Auto-reconnect with subscription replay, JWT refresh, and lifecycle events built into the TypeScript client.
Rooms for every Polymarket stream
Continuous data feeds: raw events, aggregated metrics, and on-chain balances flowing as they change. Subscribe, filter, and let data stream for as long as your socket is open.

Subscribe to live trade ticks by market, wallet, or globally as fills land on-chain.

Trending markets and events that stay live, with updates pushed as they change.

Features
JWT auth for end users
Let users connect directly with JWTs from any auth provider like Clerk, Auth0, or your own IdP. Ship a public key to the browser and keep your secret key server-side.
One socket per user
Each connection gets its own subscriptions, filters, and per-user rate limits. Plan caps scale from 1 to unlimited concurrent sockets, so one socket per logged-in user just works.
Pay per message
Credits are billed per message delivered, not per connection. Quiet rooms cost nothing beyond a 1-credit hold, and filters let you pay only for the data you actually consume.
Alerts websocket
Rooms stream continuous data; alerts fire only when something meaningful happens. 20+ pre-computed triggers (thresholds, spikes, milestones) delivered over a dedicated socket so you never run a webhook server.
Trader Alerts
Notify on specific wallets: whale activity, new traders, and PnL crossings as trades land.
- Whale trade alerts with configurable size thresholds
- First trade and new market entries per wallet
- Global, event, and market PnL milestone alerts
Market & Event Volume
Catch new markets launching and detect volume milestones or spikes on live events.
- Market-created notifications for new prediction markets
- Volume milestone alerts at configurable thresholds
- Volume spike detection for unusual activity
Price & Probability Moves
React to sudden price or probability moves on individual outcomes.
- Price spike alerts for rapid outcome price moves
- Probability spike alerts for fast market shifts
- Close-to-bond alerts for near-certain outcomes
Metric Thresholds
Cross-threshold alerts on aggregated event, market, and position metrics.
- Condition-level thresholds on volume and transaction counts
- Event-level rollups across all child markets
- Position volume milestone and spike detection
Crypto Asset Alerts
Chainlink-sourced alerts for tracked crypto assets: ticks and candle windows.
- Tick alerts for raw Chainlink price updates
- Window alerts when asset candles open or close
- Per-symbol subscriptions or all-asset firehose
