Pricing
No row meter, no credit meter, no per-instrument-day arithmetic. Every market we record is in every paid plan, including the thin ones nobody else bothers to capture.
Where this sits in the field: paid entry runs 19-49 USD and the top of self-serve 249-549 USD. We price in that band, and the difference is what the price buys - every market we record with no row, credit or request meter, instead of a history window or a request budget. What we do not have is the longest archive; the book tape starts 2026-11-07 and grows daily, and subscribers get all of it, whenever they join.
An order is invoiced, not charged: nothing here collects payment details. An admin approves it and the plan switches the same minute. Card checkout comes later, behind the same flow.

Nothing by row and nothing by credit. The only counter is how many download URLs a day an account signs, and the caps are set so a normal research pipeline never meets them. Quotas are read from an idempotent usage ledger rather than from request logs, so a retried request is never counted twice.
Short-lived signed URLs over object storage, one file per hour and market, in lp2 (lossless, about 7x smaller than parquet) or parquet. A CLI handles bulk and resumable sync, and the lp2 reader is open source.
The book tape runs forward continuously from 2026-11-07 and grows every day. Trades reach back to 2020, reconstructed from our own Polygon node. We say which is which instead of blurring them into one number.
It is written down. Every websocket outage is logged per shard, and every download ships with the coverage ledger for its window. You can read that ledger before buying anything, without a key.
Yes, and it is free. Apply with an institutional address and a line about the research. Access is Research-tier and non-commercial, and the only thing we ask for is a citation.
You place an order and we invoice you; approval switches the plan the same minute. Card checkout is not wired up yet, and we would rather say so than show a payment form that does nothing.
Start from the data instead: pick the series and the window, see how much there is and how well it was captured, and the plan follows.
