There are lots of options outside of the companies that make browsers and search input boxes on websites
SERP, EXA, Tavily... they are becoming a dime-a-dozen with the Ai hype b/c (1) making the process of fetch/scraping easier (2) being the primary end user of search API (3) making the creating of such an API easier
I haven't dug in enough to any of them to get a sense of result quality or consistency
