PolyNode Realtime Polymarket Data API and WebSocket Feeds

PolyNode Overview

PolyNode Key features

• Preconfirmation Data Streams

  PolyNode watches the mempool and decodes Polymarket transactions. It pushes settlements and fills to your system three to five seconds before the block confirms.

• Composable WebSockets

  You connect to eight distinct stream types on a single connection. The server runs twelve filters to send the exact data your client needs.

• Enriched Trade Objects

  Every payload has the human readable market question and outcome name. Your application can render a user interface or trigger logic immediately.

• Deep Historical Archive

  The service stores over 1.2 billion fills across 2.7 million wallets. You can query this complete record of trades with ordinary SQL.

• Wallet Tracking Endpoints

  These endpoints return realtime and historical activity for any address. You get realized P&L and category breakdowns to analyze performance.

• Oracle Resolution Stream

  The API decodes UMA Optimistic Oracle events live from Polygon. Your risk systems receive an early signal when the protocol submits a dispute or proposal.

• Realtime OHLCV Data

  The system generates candle data directly from real settlement flow. You can pull six resolutions to test strategies and build charts.

• Perps Data Coverage

  The API delivers open interest and named liquidations as time series. You can also track crowd long short ratios and whale leaderboards.

How to use PolyNode

1. 1

   Create your account

   Visit polynode.dev and create an account, or generate an API key via the documented POST endpoint. Store the key immediately because the system cannot retrieve it later.

2. 2

   Test the REST API

   Send a GET request to the markets endpoint with your key in the header. Include a count parameter to retrieve the highest volume markets.

3. 3

   Open a WebSocket connection

   Connect to the documented WebSocket endpoint and pass your key as a query parameter. You can enable zlib compression to reduce bandwidth.

4. 4

   Subscribe to a stream

   Send a subscribe message that specifies your desired stream type, such as fills or settlements. Include any required server side filters in this message.

5. 5

   Process incoming JSON events

   Read the enriched JSON events and trigger your application logic without further lookups. Send a simple ping every 30 to 60 seconds if your connection runs behind a proxy.

6. 6

   Recover missed events

   Use the since filter with a recent timestamp after a disconnect to recover events within your plan lookback window. Fall back to REST endpoints for longer gaps.

7. 7

   Query historical data

   Access the SQL explorer or the documented REST history endpoints for historical analysis. You can query past fills, positions, and redemptions.

8. 8

   Scale your usage

   Add more concurrent connections or upgrade your plan when you reach your current limits. The system accounts for these limits at the account level.

   PolyNode V3 has been live for a bit now: deeply indexed Polymarket trades, wallets, positions, P&L, redemptions, settlements, tags, builders, and time-windowed filters. All real time.
   The new piece: combos.
   We now index the combinatorial module and related contracts, including combo markets, wallet combo positions, combo trades, lifecycle activity, and wallet summaries.
   Docs:
   https://docs.polynode.dev/data/combos/overview
   https://docs.polynode.dev/data/combos/wallet-positions
   https://docs.polynode.dev/data/combos/wallet-trades
   And it is live, not just historical.
   Settlements and combo executions now stream over WebSocket from the mempool path before confirmation.

   Polymarket moves on current information.
   That means builders need more than prices and trades. They need context: what people are saying about a market, what major accounts are posting, and how the conversation is changing in real time.
   So we’re including a limited X Search in every paid Polynode plan.
   Starter: 500 searches/mo
   Growth: 1,000 searches/mo
   Enterprise: 5,000 searches/mo
   Search keywords, hashtags, accounts, phrases, and operators. Pull recent timelines from public X accounts. Add live social context to your Polymarket apps without maintaining your own X pipeline.
