The Keck Observatory Archive (KOA) has released a program-friendly interface to access public images acquired with all Keck instruments equipped with an imaging mode. The interface is compliant with the IVOA draft standard Simple Image Access Protocol v2 (June 30, 2015).
The interface is fully documented at https://koa.ipac.caltech.edu/UserGuide/program_interface.html, and includes a detailed description of the input and output parameters, examples for each of the Keck Observatory instruments, a troubleshooting guide and a web-based query builder that allows users to create queries that are later run from a program.
