Tick-by-tick Polymarket history — every quote, every book update, every trade — as clean, replayable parquet/CSV bundles and a REST API. We run the dual-region, sequence-audited capture plant; you skip the sockets, dedup, gap-fill and storage. The market you ignored last month is already on disk — we never stopped watching.
Your edge compounds in strategies, models and papers — none of it compounds in a websocket babysitter. Running your own capture is a standing job that returns nothing to the thing that actually makes money. We already run it; the hours stay yours.
Keep live websockets up around the clock — reconnect, resequence, alert on drops, forever.
Parse the raw feed, de-duplicate, cross-fill gaps and chase schema drift before a single backtest runs.
Stand up storage, retention, monitoring and a 3am page for a system that isn't your product.
A live feed only records what you were watching — last month's market you ignored is gone for good.
Polymarket's feed is real-time only — once a book update scrolls past, it's gone. Past the standing job of capturing it cleanly, what's left is fidelity — resolution, completeness, depth, replay. Here's the line-by-line difference.
Sign up before public launch and your discount never expires — not when prices rise, not when you move up a tier. Applies to both roaming plans. No tier-bumps, no weasel clauses.

On-chain trade fills reach further back — back to 2023-08, per market — thinner before 2026 — read from Polygon settlement and sold as their own layer.
