# QuanticData, free: Related keywords API

> A keyword research API that returns what people actually type. One seed is expanded into dozens of Google autocomplete probes — the a–z alphabet soup, question words, prepositions and comparison modifiers — and every distinct suggestion comes back with the probe that surfaced it and Google's own relevance score.

QuanticData's related keywords API on its Pay as you go plan. It costs $0.00 per 1,000 keywords. It returns none of the 6 key fields we check: Search volume, Monthly trend, Cost per click, Competition and 2 more.
We rank 76 plans by price. [Mangools's $15 monthly plan](https://datacircle.dev/related-keywords-apis/mangools/15-monthly/llms.txt) is the cheapest paid plan per 1,000 keywords: $0.0001. Mangools charges for each page of results. We count 10,000 keywords on each page to get the $0.0001 price.
