Bing Visual Search
Microsoft's visual and reverse-image search. The web interface still works for matching an image against Bing's index, but use is manual only. It serves as a second opinion alongside Google and Yandex when reverse-searching an image. Degraded: the programmatic API was retired in August 2025 along with the rest of the Bing Search APIs.

Por qué es útil y cómo funciona
Bing Visual Search is Microsoft's reverse-image and object-recognition search, useful as an additional perspective alongside Google and Yandex when neither returns satisfying results. The web interface still accepts image uploads and URL submissions for matching against Bing's index, though it requires interaction in the browser. Note that Microsoft retired its programmatic Bing Visual Search API in August 2025, so Echo can only offer a hand-off link to the Bing web interface; you complete the search there.
Qué contiene
Bing does not publish its image index size. Coverage draws from Bing's general web crawl, which is smaller than Google's but still spans billions of web pages globally.
