The Vast Serverless SDK is a Python pip package that provides tools for both creating serverless endpoints and sending and managing requests to those endpoints. It abstracts much of the complexity of interacting with the serverless engine and individual workers.

​
What the SDK Handles

The SDK manages the following core functions for the client:
  • Authentication
  • All communication between the client, endpoints, and individual workers
  • Request queuing
  • Error handling and retries
  • Creating and managing asynchronous sessions
  • Providing worker status and lifecycle information

​
Why Use the SDK

While there are other ways to interact with serverless endpoint — such as the CLI and the REST API — the SDK is the most powerful and easiest method to use as it incorporates all best practices for using the API. It is the recommended approach for most applications due to its higher-level abstractions, reliability, and ease of integration into Python-based workflows. If the Python SDK or CLI are not usable for your application, please contact support to request further assistance. We’re happy to help.
