One-time purchase
$5 per 30-day period. You get that period's fixed 30 days of data, with 7 days after payment to download them by API key or from the website; to download again after that, buy it again. Periods count from 2026-08-14, not calendar months. A period in progress can be bought now: published days unlock at once, the rest one by one as they are published, and the 7-day download window starts when its last day is published.

Questions
What does the subscription cover?
The most recent 60 published days (never earlier than 2026-08-14). The window moves forward each day as new data is published.
What does a one-time purchase cover, and for how long can I download it?
The data range is fixed. For 7 days after payment you can download it with your API key or from the website.
Can I combine periods and a subscription?
Yes. You can download all data still within its 7-day download window plus the subscription window while it is active. Neither affects the other.
What if a renewal payment fails?
You keep access for one more day while Stripe retries the payment. Update your payment method from your account page; as soon as a retry succeeds, access resumes. If it is still unpaid after that day, we email you and subscription downloads pause.
How do I cancel, or switch between monthly and yearly?
Account → Manage subscription. After cancelling you keep access until the end of the paid period. Monthly → yearly switches right away with the difference prorated; yearly → monthly takes effect when the current year ends.
Can I get a refund?
Purchases keep your API key. A full refund within 7 days of payment if the key has not been used since you paid; once it has — any API call, including listing or downloading files on this website — the purchase is non-refundable. Use before a purchase does not affect it. Subscriptions can be cancelled any time; unused time is not refunded.
How can I pay?
By card through Stripe, plus Apple Pay, Google Pay and other methods Stripe offers where you are. Crypto payments are coming later.
Can I share my key?
No. Keys are personal: one key per account and 300 downloads per day. Download links expire after 5 minutes.
