SERP competitors API

SERP competitors API - given a set of target Google keywords, find the domains that dominate those search results, each with how many of the keywords they rank for, average and median position, SERP rating, estimated traffic (ETV) and visibility. Unlike a domain-based competitor lookup, this starts from the keywords you want to win. For competitive SEO and content-strategy research. Empty results if none.
