- free.direct-img.link serves only unrestricted (public domain/CC0) images from Openverse (license=cc0,pdm) and Wikimedia Commons (haslicense:unrestricted), with optional ?src=openverse|wikimedia - ?i=1..20 picks the i-th working image on both sites; broken links are skipped so every index is a different image - Openverse OAuth token is cached in KV and refreshed automatically - Skip Flickr "photo unavailable" placeholders (served with HTTP 200) - Free/indexed cache keys use uppercase prefixes; plain main-site keys are unchanged so existing cache entries stay valid - Update README, homepage, privacy policy and terms Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
