Do you think in the future you might exclusively use your own index and not be depended on others?

Let's say hypothetically tomorrow, all the search API you rely on, decides to cut you off, what then? How good is your own index by itself?

Just to be clear, I am not dissing on you, it takes a lot of gutso to take on search engine market alone, I applaud you for that, I don't see myself having that much guts to do it. I am trying to be realist about the meta-hybrid-search engine.
