Where these values come from
CORS is verified by us — we read the Access-Control-Allow-Origin header from a real response (last checked 2026-07-31). Free tier and restrictions marked verified were read from the provider's own pricing page on the date shown, and that page is linked so you can re-check it yourself. Rows marked not verified are ones we could not confirm at the source, so we do not publish a number for them. Pricing and licence terms change without notice — confirm with the provider before you commit. If you spot a value that is out of date, tell us and we will correct it.
