  The only priced API product IAB Tech Lab sells is the Supply Chain API (aggregated ads.txt,
  app-ads.txt and sellers.json crawls plus Transparency Center registries), provisioned through the
  Tools Portal after a free login. Every standard, contract, library and reference agent in this profile
  is free and open source. Membership itself (https://iabtechlab.com/membership/) is priced by tier on
  request and is not an API plan.
