- The free tier is 100 requests a month, which suits testing rather than lists.
- Prices shown are for the entry volume of 5,000 requests a month; more volume costs more and the page sets it in the dashboard.
- The page says annual billing saves 10%, but its source shows the same figures for monthly and yearly, so the monthly price was not confirmed.
- The pricing page still carried a holiday discount banner with a January 3rd end date, which looked out of date.
