Built for Prediction Market Traders

Application-Ready Polymarket Data

Parsed Polymarket data for prediction markets, trades, positions, traders, and outcomes — with metadata and USD-normalized values.

OHLCV Candles for All Markets

Precomputed OHLCV (open, high, low, close, volume) candles for every market to power price charts and analytics.

Ultra-Low-Latency Real-Time Data

Sub-500ms real-time Polymarket market data for new markets, trades, and prices via Kafka or WebSockets.

GraphQL API for Polymarket & Prediction Markets

Query historical and real-time prediction market data: trades, markets, traders, positions, outcomes, and settlements.

Historical Polymarket Data (2+ Years)

Access 2+ years of historical Polymarket data, with extended history available on demand for backtesting.

The Real Problem

If you're building serious systems on prediction markets, you quickly face:

Multiple APIs for different parts of the lifecycle

WebSockets for price updates but no unified Information model

On-chain data for settlement that must be stitched manually Inconsistent historical vs real-time datasets

No deterministic replay model

Manual normalization of markets, outcomes, and tokens

Engineering effort shifts from alpha to plumbing. We eliminate that complexity.

Real-Time Prediction Market Data Infrastructure

We provide a unified, stream-first data layer for prediction markets — starting with Polymarket and expanding to other protocols. Instead of polling fragmented endpoints, you receive:

Real-time Trades

Market Creation & Resolution Events

Settlement & Redemption Events

Fully normalized Question → Condition → Outcome mapping

Kafka streams + GraphQL subscription WebSocket

Historical APIs for replay & backfill

Complete Market Lifecycle Visibility

From market creation to final redemption, every stage is captured in a unified stream: Market creation -> Market updates -> Trade executions -> Outcome selection -> Resolution -> Redemption / settlement -> Collateral flowsYou no longer need to reconstruct lifecycle state. You consume it.

Canonical Normalization Across Markets

We normalize prediction markets into a consistent model: Marketplace → Question → Condition → Outcomes → Tokens This unlocks:

Cross-market analytics

Unified indexing

Portfolio-level exposure analysis

Protocol comparisons

Scalable research pipelines

As new prediction markets are added, your architecture remains stable

True Real-Time Streaming (Not Just Polling)

Delivery options:

Kafka + Protobuf for high-throughput systems

GraphQL WebSocket subscriptions for real-time apps

Historical APIs for replay and backfill

Your system reacts as markets move — not seconds later

We Transform Raw Trade Activity Into Actionable Insight

Your stream enables:

Immediate detection of every executed trade
Identification of aggressive buyers vs passive sellers
Directional outcome flow monitoring
Real-time liquidity shifts
Detection of abnormal trade sizes
High-frequency trade monitoring

Use This To Power:

Trading engines
Market making systems
Alpha discovery models
Whale alerts
Volatility monitoring

This is execution-level trade flow — not delayed summaries.

Instant Event Detection

Markets move when:

New markets are created

Outcomes resolve

Redemption occurs

Liquidity surges

Your stream allows:

Instant resolution alerts

Early detection of newly listed markets

Real-time settlement monitoring

Trigger-based automation

Bot execution pipelines

No polling loops. No blind spots.

Trusted by the leading organizations in Web3

We Transform Raw Trade Activity Into Actionable Insight

Polymarket’s WebSocket is excellent for:

Order book updates
Market price changes

But serious systems require:

Lifecycle completeness
Settlement accounting
Replayable history
Infrastructure-native scaling
Unified normalization
Multi-protocol extensibility

Native APIs are product-facing. We are infrastructure-facing.
