Custom Search JSON API provides 100 search queries per day for free.
If you need more, you may sign up for billing in the API Console.
Additional requests cost $5 per 1000 queries, up to 10k queries per day.
If you need more than 10k queries per day and your Programmable
Search Engine searches 10 sites or fewer, you may be interested in
the Custom Search Site Restricted JSON API, which does not have a
daily query limit.
This makes it sound like 10k queries per day is the max, no matter how much you pay?
