Pricing details

The Free instance is free of charge with limited monthly quota up to 20K transactions and is great to get started with the service and to learn how to use it in your application.

The Standard instance is designed for running production workloads. Pricing is based the number of transactions you make. A "transaction" is an API call with request payload size up to 1000 data points inclusive in the time series, each increment of 1K data points will add to another one transaction.

Additionally, Anomaly Detector now supports multivariate anomaly detection. This multivariate capability is available as a separate API and is available free in preview.

Frequently asked questions

  • A transaction is an API call with request payload size up to 1000 data points inclusive in the time series, each increment of 1K data points will add to another one transaction. For example, an API call with request payload size == 2050 is 3 transactions. The maximum request payload size is 8640 data points. Each data point in time series is a time stamp/numerical value pair.

  • Usage is throttled if the transaction limit is reached on the Free tier. Customers cannot accrue overages on the free tier.
