Flickr
One of the largest photo-sharing archives on the web, holding billions of photos — a deep well of historical and community photography. Search works on the website, and a mature REST API exists for keyed access. Worth searching when you are chasing original photographs of places, events or communities from the earlier web. Degraded for new integrations: fresh API keys now require a paid Flickr Pro subscription (existing keys keep working), so plan on the web interface.
Why it’s useful & how it works
2026 CHANGE: NEW API keys require a paid Flickr Pro subscription (existing keys keep working). API reachable via proxy. Clean JSON once keyed.
What’s inside
Billions of photos.
