IncandescentAPI performs image lookups on popular services to return the websites using that image (or a modified version). It searches Google, Bing, Baidu, and Yandex image search for results and returns a JSON object containing variety of information about the pages hosting input image.
We power some of the worlds best image lookup frontends, including Image Raider, and have a throughput of several hundred thousand requests per day.
Searches are performed live – from initial input to being able to return a value, typical wait time is 15 to 20 seconds (this varies depending on the queue congestion and the amount of results our servers need to check).
All requests to the API are performed over SSL with HTTP POST. All data is sent within a JSON object contained in the POST body. See samples and documentation.
