咨询：Bing Autosuggest API中Transaction的定义及计费疑问

Great question—this ambiguity in the official docs and FAQs is definitely frustrating. From my hands-on experience working with Bing's APIs and cross-referencing how other Microsoft search-related services handle billing, here's the clear breakdown:

• Core Definition: For the Bing Autosuggest API, a transaction is equivalent to a single API call that the service processes. That means every time you send a valid request to the Autosuggest endpoint (and the service receives and responds to it), it counts as one transaction.
• Edge Cases to Keep in Mind:
  • Requests that never reach the service (like network timeouts or DNS failures) won't count towards your transaction quota.
  • Even if the API returns an empty suggestions list or an error response like 400 Bad Request (due to invalid parameters), as long as the service received and processed the request, it's counted as a transaction.
• Alignment with Other Bing APIs: This matches how Bing Search, Spell Check, and other sibling APIs define transactions—each processed request equals one billing unit.

If you want to confirm this firsthand, send 2-3 test calls to the API and check your Azure portal's usage metrics. You'll see the transaction count increment by exactly 1 for each request the service processes.
