The Computational Photography Project for Pill Identification (C3PI) is a National Library of Medicine service that intends to build a standardized information infrastructure for identifying unknown Oral Solid Dosage Pharmaceuticals (pills) from digital pictures. In addition to images, the project is generating metadata such as pill descriptions and dimensions.
The C3PI RxImageAccess API provides developer access to the projectâ€™s collected data. The API is able to query for images using numerous descriptive parameters such as color, shape, imprint, size, and much more. The API returns a customizable list of metadata, including elements such as active/inactive ingredients.
