Extra income: Custom dev based on our API, but how to find clients ?

Hi!

we are working in eCommerce scraping and have been in that field for over 5 years, unlike many current solutions we have one of the cheapest costs for crawling and yet we handle about 50mln requests for product scraping per day including scraping many sites that are hard to scrape (Amazon, Wayfair, HomeDepot, etc.).

Well, anyway, we've been doing that for our main business, however, the financials are not great and we want to diversify our income sources and one way is to offer the API (or rather custom solutions based on API) publicly, preferably to larger clients.
Where should we start ? How to find clients that would be interested in our API. We have few clients already, but they all came from our original business.

Thanks for any pointers !

Anton
