I can also (depending on industry) see a dual model (freemium vs paid):
If (generally) more data is better. As a site owner I might be happy to give free access to most of my public data and urls. You be at the mercy of my sites unique formatting and hiccups
But for some fee, I might be happy to provide api-like data access to some of my historic data that are more rich with information and promised some sort of format-encoding (AI-JSON ?)
The economics I think are still currently be discovered.
