It seems that there is no API to query the ESO archive. Astroquery uses the library BeautifulSoup to parse HTML pages of ESO archive website, extract content and aggregate data into a "tabular" structure. The search seems to fill the forms. So, it is possible to filter results on some properties (instrument name, target name, category (science, calibrator, ...), observation ID, program ID, ...). The headers related to a query result can be retrieved but it is necessary to use a list of 'dp_id'

AsproX / ESO archive

It is relatively easy to generate an Asprox file from one line extracted from the ESO archive (one OBS_ID for a defined instrument)
