Internally, VSX resolves all star names to OIDs, so it would be preferred if you determine OIDs and cache the results locally.
Please note that VSX is also available for download on Vizier. If you are going to be making many queries, I would recommend you download a copy instead as it will be considerably faster to use.
Yes, unfortunately the links to external entities is not captured in the version of VSX on Vizier.
If you are writing a new script, please be aware of the following items:
VSX will perminantly move from the url https://www.aavso.org/vsx to https://vsx.aavso.org in the next few months. The service is already running at the new URL so please use that instead.
Due to a significant increase in queries by bots over the last year, the new server has bot protection enabled. If you find your queries are getting blocked, I recommend you use Vizier to access the relevant information instead.
We intend to rewrite VSX and issue a new API later this year that will require API keys or authentication. That should, hopefully, resolve the bot issue.
Ok thanks for info. Maybe you can please reply here and place a small note if API and API keys are ready, so that I and someone else who comes here via a search then knows.
