Endpoint
GEThttps://citable.run/v1/keyword-metrics?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, multi-keyword SEO and PPC metrics in a single API call — especially when you need all five signals (volume, CPC, competition, difficulty, intent) together. Ideal for keyword research workflows, content planning, and ad bid estimation. Prefer this over single-keyword lookups when you have a batch of up to 20 terms to evaluate at once.
