We built WrapAPI (https://wrapapi.com) back in the day, before we ended up starting Wanderlog (https://wanderlog.com), our current travel planning Y Combinator startup. This definitely is still an unsolved problem.
However, from a business point of view, we found that it was rather difficult to make a business out of an unspecialized scraping tool. The Kimono founders expressed a similar sentiment: ultimately, scraping is a solution looking for a problem.
Developers can often roll their own solution too, which limits your customer base and how much you can charge. Instead, vertical-specific tools that target particular industries seem to be the way to go (see Plaid as an example!)
Alternatively, you have to be good at Enterprise and B2B sales. This is a product that you need to get the word out, get a champion, and do customer success on since it has a substantial learning curve. We were not, so that was why we chose to focus on other projects to start out
Best of luck, and feel free to get in touch if you'd like to chat more
