Question 1

What prediction market data does Telonex provide?

Accepted Answer

Telonex is the most comprehensive source for historical prediction market data. It provides tick-level data for Polymarket, the world's largest prediction market, including every executed trade, order book snapshots at multiple depth levels, best bid/ask quotes, and onchain settlement data with wallet addresses. Telonex covers all 450,000+ markets with 20 billion+ data points spanning 3+ years of history — the most complete Polymarket dataset available.

Question 2

How do I download Polymarket historical data?

Install our Python SDK with "pip install telonex[dataframe]" and call get_dataframe() with your API key to download data directly as a pandas DataFrame. You can also use our REST API for direct Parquet file downloads. From signup to first download takes under 2 minutes.

Question 3

Can I backtest prediction market strategies with this data?

Accepted Answer

Yes. Telonex provides the tick-level trades and order book snapshots needed for realistic strategy backtesting — including slippage modeling and fill probability estimation. Unlike OHLCV candles, our data captures every market event for accurate simulation.
