Hi @Amardeepthi Venkata Siripurapu Thank you for posting your question on Microsoft Q&A.
Unfortunately calling API from Azure stored procedure is not supported for PaaS (Azure SQL DB).
If you need to do something similar, SQL Managed Instance has CLR (CLR is not supported in Azure SQL neither)

Please feel free to reach out if you have additional queries.
