Requires ?country=<ISO 3166-1 alpha-2, e.g. US>; optional ?date=YYYY-MM-DD or ?year=1975..2100. Errors: 400 bad_country (a 3-letter code like USA is rejected)|bad_date|bad_year, 404 unknown_country.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
