Prices are estimates only and are not intended as actual price quotes. Actual pricing may vary depending on the type of agreement entered with Microsoft, date of purchase, and the currency exchange rate. Prices are calculated based on US dollars and converted using London closing spot rates that are captured in the two business days prior to the last business day of the previous month end. If the two business days prior to the end of the month fall on a bank holiday in major markets, the rate setting day is generally the day immediately preceding the two business days. This rate applies to all transactions during the upcoming month. Sign in to the Azure pricing calculator to see pricing based on your current program/offer with Microsoft. Contact an Azure sales specialist for more information on pricing or to request a price quote. See frequently asked questions about Azure pricing.

Frequently asked questions
-
In the S tier, the service is billed for only the amount of Text Records submitted to the service.
-
A text record in the S tier contains up to 1,000 characters as measured by StringInfo.LengthInTextElements. If an input document into the Language 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 8 text records. If an input document sent to the API contains 500 characters, it would count as 1 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. You can check your text records usage in your Text Analytics resource in Azure portal under Monitoring > Metrics > Processed Text Records.
-
Usage is throttled if the transaction limit is reached on the Free tier. Customers cannot accrue overages on the free tier.
-
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 × 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. S0-S4 tiers have been deprecated. Guide on how to migrate.
-
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. S0-S4 pricing tiers are now deprecated and you are encouraged to switch to S tier. Guide on how to migrate
-
Orchestration workflow only charges you for requests to the Orchestration endpoint. If the orchestration workflow project routes your request to another conversational language understanding, custom question answering, or LUIS project, you are not additionally charged for the call to that service.
