Terms of sale

What you buy

Access to download the files of the UTC days in your order. One day of a type is the Polymarket market file plus the exchange files for the same coin and day, as listed on the type's page before you buy. The coverage of every file is shown there too, so what a day contains is known before payment.

What you may do with the data

• Use it internally, inside your own organisation, for any purpose: research, backtesting, trading, training models.
• Publish what you make from it — results, charts, papers, models, aggregated statistics — as long as the files themselves cannot be rebuilt from what you publish.
• Not redistribute the files or substantial parts of them: no resale, no public mirrors, no sharing outside your organisation.

The free samples are different: share them freely under CC BY 4.0, crediting keydata.shop.

Where the data comes from

We record the public market-data feeds of Polymarket, Binance, Bybit, OKX and Coinbase, and the Chainlink price feed as Polymarket publishes it, on our own collector; Binance spot before 2026-06-17 comes from Binance's public 1-second dump. What we sell is our capture, its timestamps and its processing. We are not affiliated with or endorsed by any of these venues; their names belong to them, and their own terms continue to apply to the underlying market data.

As is

The data is provided as captured. Feeds drop, and the gaps we know of are measured and shown — the coverage of every file, and the limitations listed in the data format. We do not promise that a day is complete or that the data fits any particular use. Nothing here is investment advice. Our liability for an order is limited to what was paid for it.

Delivery

Access opens once the payment is confirmed. Files can be downloaded for 30 days after that, as many times as you need, up to 3 times the size of the order in total. The order link is the access: keep it private. An order whose link is shared publicly may be revoked.

If we correct a file, every order that holds its day gets the corrected one at the same link, and the download script fetches it again on its next run.

Payment

Prices are in USDT and paid in crypto through a payment provider. The full invoiced amount has to reach the payment address: network and exchange withdrawal fees are on top of it. A payment that arrives short leaves the order unpaid — write to us with the order link and we will sort it out.

Refunds

An order can be refunded until the first file of it is downloaded. Write to us with the order link and an address for the same coin you paid in; the refund is the amount received, less the network fee of sending it back. Once downloading has started there is no refund, but a missing or broken file is fixed or replaced.
