POSThttps://seolyticize.com/api/v1/tools/research_topic

Maps a topic: related keywords and keyword suggestions for a seed, with volume, difficulty and search intent, grouped into subtopics by the word they add to the seed; the questions people ask (People Also Ask and question keywords); and the headlines ranking now. Answers 'what should we write about around this topic'. Paid DataForSEO Labs reads and one results page on the client's account, each free when anyone read it lately.

Parameters

Idempotency-Keystringheader
Any unique string, up to 200 characters. A retry with the same key and body is answered from the first answer (Idempotent-Replayed: true) for a day, so it never buys or writes twice; the same key with another body is refused.

True to buy nothing and get the quote instead: what the call would cost at most and what it would buy.
