Thanks a lot regarding UI and good point on the schema editing.

We've been having similar thoughts about pricing and offering unlimited, but since it is feasible for us in the short term due to credits we enjoy offering that option to early users, even if it may be a bit naive.

Having said that, we are currently working on a pilot with a company whom we are offering live updates, and they are paying per usage since they don't want to have to set it up themselves, so we can definitely see the demand there. We also offer an API for companies that want to reliably query the same thing at a preset cadence, which is also usage based.

For crawling we use Firecrawl. They handle most of the blocking issues and proxies.
