keywords.duoleads.com/v1/keyword-gap

Keyword gap: the Google keywords a competitor ranks for and your domain does not, each with the competitor's position, URL and estimated traffic plus search volume, CPC, difficulty and intent; up to 100 in one $0.048 call. Use when you need content gaps and keyword opportunities (bare domains; www. is dropped). No gap returns empty results (still charged). Bad input is free; upstream errors are not charged.
