Keyword Research API
A keyword research API is an endpoint that returns keyword ideas and their metrics — most importantly monthly search volume — as JSON, letting an application generate keyword suggestions and volumes automatically rather than through a manual research tool.
What it returns
Given a seed keyword, the API responds with related keywords and a search-volume figure for each, so software can size demand and build keyword lists without a person clicking through a web interface. Results come back as JSON your code can sort, filter and store.
Why it is useful
A keyword research API automates the slow part of SEO and content planning. You can score thousands of ideas, refresh volumes on a schedule, or power your own keyword tool on top of the data.
