I couldn't commit to doing this so it'd be a good time for a new maintainer to come forward (I could help this person a bit if needed).

It might also be the time for a more complete re-write (i.e. not only replacing URLs and applying some tweaks) if someone is up for this.

Hi! Thanks! I am interested in taking it up. Let me know how to move forward.

Removing the "help wanted" label for now as @adithirgis and I are discussing this in another medium. Thanks for volunteering Adithi!

Some notes on my efforts to push a small update to CRAN (to fix the current version of the package, and re-record the cassettes following crul update cc @sckott). See #62

• The API status URL is now https://api.openaq.org/ping and when all is good it returns "Healthy Connection", not "green".
• In the current code before making many requests I query the API once to know the total number of results. For doing that I used to do a query with "limit=0", but now if one does that one gets 0 result so one needs to do "limit=1".
• I thought I'd continue making some tweaks until all tests pass again but no, the API now returns 403 i.e. I have been blocked!
• Then I got de-blocked and made some more progress, and got another error with different output from the API... I think it shows one should not use the version 1 of the API and I'd much rather save time for helping with the migration to V2 when someone does that.

So tl;dr it is impossible for me to keep the package working with the version 1 of the API. Therefore, I will request archival on CRAN. Then I can help @adithirgis get this package ready with the version 2 of the API.

If anyone needs OpenAQ data via R before then, they'll have to query the version 2 of the API themselves with httr or crul or curl https://docs.openaq.org/#/

Hello here, httr2 was released https://httr2.r-lib.org/ -- maybe the new code could use it?
