Professional is the full product: trades, OHLCV, reconstructed snapshots and market stats, plus the raw, event-granular L2 order-book delta tape. It is what you want if you are modelling microstructure, queue position or execution quality. Paying annually costs two months less than paying monthly and deepens your history window from 12 months to 24. A free tier gives delayed daily candles and top-of-book so you can evaluate the coverage and data quality before committing.

Your plan is unlimited, bounded by a monthly fair-use cap set well above normal research use — 50 GB on Professional. Volume is measured as compressed Parquet, which is highly efficient — 1 MB typically represents tens of thousands of orderbook snapshots or trades. Past the cap, pulls pause until your next billing date; if you need more, contact us before you reach it.

They stay on your account, they never expire, and they can be redeemed toward a subscription. Nothing you have already paid for is lost.

Yes, any time. Cancelling stops the next renewal and your access runs to the end of the period you have already paid for — no exit fee, nothing clawed back. Upgrades take effect immediately, so you can move up mid-month if a project needs deeper data.

Every download is available as CSV, Parquet, or JSON. Parquet is the industry standard for columnar analytics — Pandas, Polars, DuckDB, and virtually every data tool can read it natively.

Prediction markets and event-contract venues: Polymarket (global + US/QCX) — our flagship raw L2 order-book delta tape plus trades, reconstructed snapshots, lifecycle, OHLCV, and wallet analytics — alongside Polymarket US, Hyperliquid, and Limitless. We also retain a multi-year crypto archive: Deribit (BTC/ETH options + futures, since 2016) and Lyra/Derive (BTC/ETH options, since 2024). New venues are added regularly — full catalogue lives in your dashboard.

Our flagship is the raw, event-granular L2 order-book delta tape — every book change captured at the moment it happened, captured live from the venue feed since June 2026 and not reconstructable after the fact. We hold event-granular L2 delta history for Polymarket, Hyperliquid, Polymarket US and Limitless — captured fresh since June 2026 and growing daily. Reconstructed L2 snapshots are a secondary product: as often as every 5 seconds for Polymarket markets near expiry, ~5 minutes for other venues. Trades are indexed continuously from each venue's API or the Polygon blockchain — Polymarket trades reach back to February 2024. Most products lag real-time by under a minute.

All major credit and debit cards, via Paddle. More payment options coming soon.

Yes. Every account gets an API key. You can automate downloads programmatically — perfect for running daily data pipelines.
