The cheapest SERP API is a free one
Every “cheapest SERP API” comparison ends the same way: a per-request price, a monthly minimum, a key. FreeSerp removes the line item entirely — it is a free SERP API on our own 3.1B+ page index, with no key, no signup and no metered billing.

FreeSerp is built for exactly that — one GET request returns ranked JSON: url, title, snippet, language, publication date and a site card with Domain Rating. There is nothing cheaper than free, and nothing simpler than a keyless endpoint.
