Many thanks! You're absolutely right, we'll publish the price ASAP and also provide some long-term guarantee for users who will depend on our service. BTW do you think pricing per GB downloaded is reasonable or would you prefer some flat monthly fee?

Can't speak for the OP but I'd vastly prefer either a flat fee (maybe tiered based on parallelism) or something like price per page, makes it much easier to estimate usage.

You're right, price per request would be easier for estimation. But as you can use JavaScript, you can scrape whole website with just one page request (see the SFO flights example). In other words, our costs doesn't correlate with page requests, but with data transfer.

Flat fee is also possible, but we think that it's fair that users pay based on their consumption.
