Pricing card displays only the USD 12.42/month equivalent ("Billed annually") without printing the annual invoice total on the public page.
3 plan / billing-period records, all listed; — means that period is not recorded.
The official /pricing/web page lists Web Free (USD 0, 20 images/session, max 5 MB/file, 3 format conversions/session), Web Pro (displayed as USD 3.25/month billed annually, unlimited compressions, max 75 MB/file), and Web Ultra (displayed as USD 12.42/month billed annually, unlimited compressions and conversions, max 150 MB/file). Because the Web Pro and Web Ultra cards display only rounded monthly equivalents ("Per month | Billed annually") without printing the annual invoice totals on the card, the annual totals are marked unverified.
Verification has gaps; unknown prices and quotas are not inferred.
