USER GUIDES
Buying and downloading data
How do I choose the right data?
Compare provenance, coverage, limitations, freshness, quality results, approved preview rows, version, price, and author information. Confirm that the data fits your intended use before adding it to the cart.
How do licenses and permitted uses work?
Review the exact license version, permitted uses, restrictions, retention requirements, and prohibited uses before accepting it. Your order keeps a snapshot of the license you accepted.
Can I add items without signing in?
Yes. You can browse and build a cart as a guest. DataMarket asks you to sign in before checkout so it can verify your email, eligibility, intended use, cart, and license acceptance.
Why is my payment still pending?
A browser redirect does not confirm payment. The order remains pending until DataMarket receives and verifies the payment provider's webhook. Refresh the order page after a short wait; contact support if the provider charged you and the status does not update.
Where can I find my order?
Open Your orders after signing in. Each order shows its receipt, payment state, exact purchased version, license snapshot, author allocation, and available download action.
How do I download and verify my data?
Open the paid order and request its download. Download links are short-lived and tied to your entitlement. Compare the displayed checksum with the downloaded file to verify integrity.
What should I do if a download does not work?
Return to the order and request a new link because an old link may have expired or already been used. Confirm the order is paid and your entitlement is active. If it still fails, email support with the safe order reference and the displayed error—not the signed URL.
What is my signed license and delivery record?
When available, save the separate delivery record from your paid order and keep it with the purchased file. It binds an opaque recipient code to the file checksum and accepted license without changing the Data. It contains no buyer email or account identifier. It documents a licensed delivery; it does not prevent copying or establish who redistributed a file. The record can be removed from a shared copy.
What are the safety and refund policies?
Raw redistribution, prohibited uses, privacy violations, and use outside the accepted license are not permitted. Completed digital sales are generally final. Legal issues, duplicate charges, paid orders without entitlement, failed delivery, or artifact mismatch require support review.
