Clarifications on google custom search API v1 parameters and pricing

Vote count: 0

I am experimenting with the google custom search API (free version) for performing image search. I would like to commence with the paid version. However, I have some difficulties in understanding the pricing and some documented query parameters in the API calls at http://ift.tt/2jYZ7Wi

1) In the free version, we have 100 queries/day. If I understood well, 1 query means a single API call. This call can return a maximum of 10 (since the parameter 'num' takes a maximum value of 10) results only. Is this both for free and paid versions? Or is it possible to retrieve more results per API request in the paid version? Precisely, can 'num' take values greater than 10?

2) The parameter 'start' is documented as index of the first result to return. In the free version, I cannot get more than 100 results for a specific query (parameter 'q'). To summarize precisely, I can get 10 results/API call, each call with parameter 'start' taking the values 1, 11,... 91 and same value for 'q'. The API call returns an error for any value of 'start' greater than 91. Is n't the free version supposed to allow 100 API calls? Or perhaps, this restriction is placed to avoid being able to retrieve more than 100 results per search term 'q'?

3) In the paid version, are API calls which return non-200 responses billed for as well?

4) In the paid version, how many API calls can be made for a specific search term 'q'?

5) Do you think there are particular restrictions with respect to the number of results that apply specific to image search only?

Thanks in advance for your help.
