The ESO science archive is now equipped with new powerful interfaces which allow the astronomical community to discover and access its content, both interactively and programmatically. The latter is best suited to enable AI investigations on the full content of the ESO archive. The ESO programmatic access layer allows the discovery of science reduced data, scientific catalogues, raw data, calibration reference files, measurements and profiling of various atmospheric parameters of the La Silla Paranal observatory, and also of the ALMA science data. These data are all exposed via the same standard interfaces allowing an increased level of discoverability of the entire archive content, and is therefore a way to maximize the scientific return of the observatory.
