Cognitive Services pricing – Text Analytics API

Use intelligence APIs to enable vision, language and search capabilities

Text Analytics is an AI service that uncovers insights such as sentiment, entities and key phrases in unstructured text. Text Analytics includes four main functions: Sentiment analysis, key phrase extraction, language detection and named entity recognition.

We are also introducing Text Analytics for health, which uses natural language processing to find and label information in unstructured clinical documents. There is no charge to use Text Analytics for health during public preview. This is a gated feature; learn more about the gating process here. Pricing will be released when the feature goes GA.

Pricing details

Text Analytics can be purchased in tiers.

Text Records correspond to the number of 1,000-character units within a document that is provided as input to a Text Analytics API request.

Frequently asked questions

  • 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.
  • Let’s say that an API call performs both sentiment analysis and key-phrase extraction on 1,000 documents, that will count for 2,000 transactions (2 × 1,000 documents). The maximum size of a single document is 5,120 characters as measured by StringInfo.LengthInTextElements. If a document has more than 5,120 chars then we do not process that specific document and show invalid document as the error. If a request has multiple documents, then we process all documents which are less than 5,120 characters.
  • 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 StringInfo.LengthInTextElements. 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.
  • Standard pricing (S instance) is text records-based pricing and enables you to use the latest capabilities of text analytics. It is more cost-effective vs using transactions-based pricing. Guide on how to migrate
