Wikimedia Commons
The largest repository of freely licensed media, over 110 million files, behind Wikipedia and its sister projects. Everything is searchable on the website, and the standard MediaWiki API serves the same search without a key. Reach for it when you need openly licensed images and other media with documented sources and licensing.
Por que é útil e como funciona
The go-to source whenever a search needs openly licensed images with clear provenance. Every file carries licence information and sourcing, which matters in research and publishing contexts. You can search by keyword directly on the site, filter by media type, and sort by relevance or recency. The same search is available via a keyless API, so Echo can surface results programmatically without any sign-in.
O que há dentro
Over 143 million freely licensed media files as of 2026, spanning photographs, illustrations, audio, video, and documents. Images alone account for around 120 million files, with the rest split across audio, video, and PDFs.
