Data API


The Data API at offers programmatic access to annotations and perturbational signatures from multiple data types including L1000, Cell Viability, Imaging, Proteomic and Cell Line meta data. These services support complex queries via simple HTTP GET requests that can be executed in a web browser or any programming language. The results are returned as standard JSON objects.
