The CDS is releasing today the first version of the API allowing one to access programmatically its cross-match service. Through HTTP calls, any script or program can submit a list of positions (up to 2 million positions) and look for counterparts in one of the 10,000+ VizieR tables.

Full documentation is available at https://cdsxmatch.cds.unistra.fr/xmatch/doc/cross-match-API.html, along with some usage examples in several languages (shell script, Python, Ruby, Java).

Your comments, questions or feedback are welcome and can be sent to cds-question@unistra.fr
