Why it happens

Official docs (MicrosoftDocs bing-docs, query parameters reference): the market parameter gotchas. mkt is language-country like en-US. mkt and cc are mutually exclusive, do not send both. To see which market Bing actually used for a request, inspect the BingAPIs-Market response header. Keep offset below totalEstimatedMatches minus count, otherwise you page past the end.
