Do I need a plan to use the numbers?No. Everything published on this site is free to read, chart and quote under CC BY 4.0, with attribution, and source data keeps its own licence. A plan is only for calling the API.
Do I need a card to start?No. Create an account and you have 1,000 requests a month with one key. Every plan reaches the same endpoints and the same data; a card comes in only when you upgrade.
What happens when I hit a limit?The API answers 429 and nothing is billed. For the per-minute limit, wait and retry with backoff. The monthly ceiling resets on the first of the month, or sooner if you change plan.
Is the free tier time-limited?No. It is a permanent tier, not a trial. Nothing on this site can charge you without you choosing a plan first.
Can I upgrade, downgrade, or cancel?Yes, from the dashboard's billing section, which hands you to Stripe's portal. Check the effective date it shows before confirming. A cancellation returns the workspace to Free at the end of the paid period.
Is the data different on paid plans?No. Plans differ in the monthly ceiling, the per-minute limit and the number of keys. Coverage still varies by country and dataset, and the site says where.
Can I use the data in a commercial product?Commercial use is subject to our Terms and to the terms of each underlying dataset. For public republication, attribute the original source; the source field on every observation names it.
