Landing page captured for the 2026-09-14 issue.

Field notes

The project builds a comparison table from pricing and terms pages rather than summarizing providers from memory. It records whether a service offers screen access, CSV, PDF, reports, API, or JSON delivery, and separates stated prices from cases marked as unconfirmed. Its summary reports 30 providers with visible prices, 40 describing some free allowance, and 11 that could not be opened during the check.
