yep.com is still in beta, the api.yep.com does not have paging support. There
is only a 'limit' argument with a maximum of 100 results.
yep.com seems fast; there is nor need for a timeout of 12 sec.
The API returns JSON nevertheless what the HTTP header is, the "show more"
button on yep.com's web site does not set a special HTTP Accept header.
FYI: The index does not support languages, the WEB UI does not offer a language
selection of the results and the entire index seems in English.
