Having tried this a bit I do really like the single api call for all of it.

I also appreciate transparent pricing but I am not 100% sure the sense of scale of costs. It could be helpful to give some ballparks on things for each of the plans. I'm not sure exactly what i could get out of a plan. My guess, trying hard to figure it out, was if i had about 1,000 pages of new/updated content per month, I would pay $295/month for unlimited queries on top of it. Is that roughly correct?

Yes, we don't charge for queries. For $295, you're able to index up to 1000 pages of new content per month into a fully queryable pipeline.

Advanced and Basic do play a difference though. Advanced is for complex graphics or charts in the documents submitted. Basic is sufficient for most document workloads.
