keywords.duoleads.com/v1/keyword-variations

Keyword variations: long-tail Google searches that contain a seed phrase, each with search volume, CPC, competition, keyword difficulty and search intent; up to 100 in one $0.04 call (Google Ads data). Use when you need phrase-match ideas for a keyword, sorted by volume. No matches returns empty results (still charged). Bad input is free; upstream errors are not charged.
