FAQ

  • The Text Analytics API can be purchased in units of the S0-S4 tier at a fixed price. Each unit of a tier comes with included quantities of API transactions. If the user exceeds the included quantities, overages are charged at the rate specified in the pricing table above. These overages are prorated and the service is billed on a monthly basis. The included quantities in a tier are reset each month. In the S tier, the service is billed for only the amount of Text Records submitted to the service.
  • Usage is throttled if the transaction limit is reached on the free tier. Customers cannot accrue overages on the free tier.
  • Any annotation to a document counts as a transaction. Batch scoring calls will also take into consideration the number of documents that need to be scored in that transaction. So for instance, if 1,000 documents are sent for sentiment analysis in a single API call, that will count for 1,000 transactions. If an API supports more than one annotation operation, that will also be considered. Let’s say an API call performs both sentiment analysis and key-phrase extraction on 1,000 documents, that will count for 2,000 transactions (2 annotations × 1,000 documents).
  • If the usage on the S0-S4 tier is exceeded, the account starts to accrue overages. These overages are billed on a monthly basis and are calculated at the rate specified for each tier.
  • You may upgrade to a higher tier at any time. The billing rate and included quantities corresponding to the higher tier will begin immediately.
  • A text record in the S tier contains up to 1,000 characters as measured by String.Length. If an input document into the text analytics API is more than 1,000 characters, it counts as one text record for each unit of 1,000 characters. For instance, if an input document sent to the API contains 7,500 characters, it would count as eight text records. If an input document sent to the API contains 500 characters, it would count as one text record. If two documents are submitted, one document of 500 characters and one document of 1,200 characters, then the service would be billed for three text records in total: one record for the 500 character document and two text records for the 1,200 character document.
