TickFoundry: Polymarket historical order book and tick data

TickFoundry Overview

TickFoundry Key features

• Tick level history

  You can replay quote changes and individual trades rather than rely on candle averages. Polymarket order book capture starts on 11 May 2026, with coverage varying by market.

• Historical order books

  Study 25 levels of bids and asks on every update with Premium or above. Explorer includes 10 levels per side.

• On chain fills

  With Premium or Professional, you can check settled Polygon fills against the trade tape and study wallet activity. Coverage reaches back to August 2023 for some markets, with fewer records in the early years.

• Downloadable data files

  Load market day bundles as Parquet or CSV, with nanosecond receive timestamps. Use the reference dictionary to match token IDs to market questions and outcomes.

• REST API access

  On Explorer and above, you can request and download market day bundles through REST. Explorer allows 150 downloads per day; Premium allows unlimited downloads under fair use.

• Whole venue access

  Paid subscribers can choose any available market day across the catalog without buying access to specific markets in advance. For a single date, you can also pay $2 for L1 or $4 for full depth without a subscription.

• Dual region capture

  The TickFoundry team records the feed in two regions, checks sequence numbers, and fills gaps with data from the second collector. Professional users can also access raw websocket messages to rebuild books themselves.

• Perpetual futures data

  Premium and Professional subscribers can access Polymarket perpetual futures books and trades, plus funding and open interest records. Capture starts on 31 July 2026; Explorer users pay extra for access.

• Reference price feeds

  Compare prediction prices with Binance and Chainlink data on Premium or Professional. You also get 30 second and 60 second time weighted average prices used by crypto up or down markets.

• Scheduled data delivery

  Premium subscribers can collect files through SFTP with hourly updates. Professional and Enterprise customers can use dedicated S3 delivery and request hourly or faster delivery.

• Free sample access

  Download a full BTC Up or Down 4h market day without an account, including an hour of raw websocket messages to check against the files. A free account gives you five more market days to test.

How to use TickFoundry

1. 1

   Download the free sample

   Open tickfoundry.com and download the BTC Up or Down 4h sample for 19 August 2026 in Parquet or CSV format. You do not need an account.

2. 2

   Check the sample files

   Read README.md and the reference dictionary, then load the book and trade files in pandas or DuckDB. Compare the L2 data with the included hour of raw websocket messages to check the recorded updates.

3. 3

   Create a free account

   Sign up for a free account to claim five market days from the catalog. Use these days to test data for the markets you want to study.

4. 4

   Pick a market day

   Search the catalog by series or event and select a UTC date. Check coverage for that market and date before you request the files.

5. 5

   Choose your access

   Claim a free day, buy a single market day, or choose a subscription, with Explorer for 10 levels of depth and Premium for 25 levels plus on chain fills. For commercial work, contact TickFoundry about Professional or Enterprise before you use the files in a product or client report.

6. 6

   Save your API key

   If you want REST access, choose Explorer or above and create an API key in the dashboard. Save it securely when you create it, because you can view it only once.

7. 7

   Request your bundle

   Request the selected market day through the dashboard or REST API. If you use REST, poll the staging job until the bundle is ready, then download or stream it.

8. 8

   Prepare the data

   Read the bundle README for coverage gaps, then load the files and match book data with trades using condition_id and token_id. Sort rows by ts_recv_ns to reconstruct the book at the time you want to study.

9. 9

   Add related feeds

   On Premium or Professional, download on chain fills if you need wallet level trade data. For crypto research, pull the relevant perpetual futures or spot feeds for the same time window.

10. 10

    Set up recurring delivery

    For repeat downloads, use SFTP on Premium or arrange a dedicated bucket on Professional or Enterprise. Keep file hashes for any data you use in published research.
