The Snowflake SQL API is a REST API that you can use to access and update data in a Snowflake database. You can usethis API to develop custom applications and integrations that:
Perform queries.
Manage your deployment (e.g. provision users and roles, create tables, etc.).
Capabilities of the SQL API¶
The Snowflake SQL API provides operations that you can use to:
Submit SQL statements for execution.
Check the status of the execution of a statement.
Cancel the execution of a statement.
Fetch query results concurrently.
You can use this API to execute standard queries and mostDDL and DML statements.See Limitations of the SQL API for the types of statements that are not supported.
For queries, the SQL API returns data in partitions. Snowflake determines the number of partitions returned and the size of each partition.
The endpoint for the SQL API (/api/v2/statements) is protected by the network policiesthat restrict access to the account where the API is enabled.
Note
The AUTOCOMMIT parameter must be set to TRUE per query or statement level, regardless of thevalue set at the user or account level.

The SQL API does not currently support Python stored procedures.
Billing considerations when using the SQL API¶
The SQL API leverages the cloud services layer when fetching some query results. For more information about cloud services,see Cloud Services Credit Usage.
