What is Telonex?

For microstructure research, choose the relevant venue and channel rather than assuming one uniform history. Telonex lists Polymarket, Polymarket Perps, Predict.fun and Binance Spot, with separate start dates for each venue and data channel. Long on-chain coverage does not imply equally long order-book recording. Date-partitioned Parquet files can be loaded into DuckDB, Polars or pandas for your own analysis.

Snapshots initialize a market state, subsequent events reconstruct book changes, and reference ticks retain source and receive-time context. On-chain fills support wallet research but are a different record from captured order-book events. These are daily historical downloads, not a live execution feed or a supplied strategy backtest engine. Model LP rewards, fees and available depth separately, and confirm historical revision handling: point-in-time accuracy options are specifically listed for Enterprise.

Who it is for

  • Quants reconstructing historical market microstructure.
  • Researchers studying wallet flows and execution records.
  • Developers building historical datasets with DuckDB, Polars or pandas.

Features and coverage

  • Daily snapshots

    Initialize a replay from a saved market state.

  • On-chain fills

    Study wallet-level activity on the supported chains.

  • Crypto reference ticks

    Compare source-price and receive timestamps when aligning reference data.

  • Normalized Parquet

    Load date-partitioned files into standard analytical tools.

  • Public metadata

    Browse market titles, outcomes, identifiers, status and tag datasets without an account.

  • REST and Python SDK

    Automate discovery and download of historical files.

Getting started

Before you start: Historical download delivery is different from live execution data.

  1. Inspect the dataset catalog and sample files.
  2. Check the start date of every required channel.
  3. Create an account and API key for downloads.
  4. Download a small date partition.
  5. Validate event order, units and identifiers.
  6. Confirm the licence scope before using the data in a product.

Daily historical files are not a live execution feed.

Useful links

What to check

  • Historical download delivery is different from live execution data.
  • History begins on different dates for different venues and channels.
  • Point-in-time accuracy is specifically listed in Enterprise; confirm historical revision handling for the selected plan.
  • LP rewards, fees and executable depth require separate modeling in a backtest.
  • Personal-use plans do not replace the published Enterprise commercial licence.

Our take on Telonex

Daily files, event-level books and distinct channels support reproducible historical research. Venue and channel start dates and personal/commercial licences must fit both the analysis and intended reuse.

Frequently asked questions about Telonex

Which file format is provided?

Parquet, organized into date partitions.

Can I access metadata for free?

Market and tag datasets are listed as public without an account.

Is 3 years of history available for every channel?

No. Coverage is channel-specific, and long on-chain history does not establish the same order-book history.

Which plan covers firm or commercial use?

The published Enterprise licence provides commercial use; the paid Single Exchange and Pro plans are described as personal-use.
