I pay for a tool to convert HTML/CSS into PDFs https://www.princexml.com/ and it seems to work well. I don't have the best idea of how it compares to the various free options though.

I tried to grep the code for `api.` to get a sense for all the vendors this codebase is using, and which you'd need to have relationships with to run the code. Here's what I found:

payments:

  https://api.paypal.com 
  https://api.stripe.com

  https://api.taxjar.com
  https://api.vatstack.com (EU VAT)
  https://apiservices.iras.gov.sg

  https://api.appstoreconnect.apple.com 
  https://api.storekit.itunes.apple

  https://api.iffy.com  (AI content moderation)
  https://api.helper.ai (AI support)
  https://api.openai.com

  https://api.easypost.com  (shipping labels?)
  https://api.sendgrid.com (email)
  https://api.pwnedpasswords.com (haveibeenpwned)
  https://api.worldbank.org (for purchasing power parity?)
  https://api.dropboxapi.com (for "upload from dropbox"?)

Deleted this post because I don't think a random screenshot from my email is a good source for people to refer to. A better source might be the bitly terms of service: https://bitly.com/pages/terms-of-service (1.4 Destination Preview)

Yes! Katie and I made it into a zine because I was such a huge fan of her work on https://ohshitgit.com/. (you'll notice she's a coauthor of the zine)

That's a great idea, thanks.
