April 14, 2026 – The Art Institute of Chicago's API includes a boolean field named "has_not_been_viewed_much" that indicates whether an artwork has been viewed fewer than 200 times on its website since January 1, 2010, according to the source code. The metric is intended to highlight artworks with low online engagement. The description was provided in a blog post by iamwillwang.com, which detailed the API's parameters. The threshold of 200 views is based on cumulative counts from the site's launch in 2010 through the present. The author encouraged readers to explore the low‑viewed works, noting that the definition does not specify why view counts are low. The API serves as a resource for developers analyzing visitor patterns and identifying under‑examined pieces.
