Google Autocomplete API
The Google Autocomplete API returns the real query suggestions Google shows as you type, as clean JSON from the API, or the same rows as CSV. Give it a seed word and get the ranked completions back in order.
One request, real response
Those same suggestions are available as a CSV table that drops straight into Sheets or a keyword sheet:
Add gl and hl for country and language. This one query returned 10 suggestions, in the order Google ranks them.
The full response, ready to use
Each suggestion is one field, the completed query, and the array order is Google's own ranking. The same record as CSV, ready for Sheets or a database:
Or the complete response as JSON, with the search parameters echoed back:
Change q to any seed and the suggestions follow the same shape, so one loop over a list of seed words builds a full keyword map.
vs serper and serpapi
All three return Google autocomplete as JSON. The difference is how you pay and what you keep.

One credit per successful search
Prepaid packs, and credits never expire: 25k for $49 · 100k for $149 · 500k for $549 · 2.5M for $1,999 · up to 250M, all self-serve, ex-tax. A search costs one credit however many suggestions come back; a search that returns none costs nothing.
Real search demand, one seed at a time
One seed word surfaces how people actually phrase a search. Feeding coffee returned local intent like coffee near me and coffee shops near me, product intent like coffee maker and coffee grinder, and category terms like coffee table and coffee shop, so a keyword list, a content plan, or a PPC seed set is built from the first response instead of guessed at.

Read this as a live demand signal, not a fixed dataset: these are Google's public search suggestions, the same drop-down list anyone sees while typing in the search box. They shift by region and change over time, and Google does not publish them as a supported product, so use them for keyword research, content planning, and demand tracking. If you need a contracted, versioned dataset with guarantees, that is a different kind of feed.
