This module focuses on the practical implementation of HTTP communication with Large Language Model endpoints using Python. You will learn to construct complex JSON payloads, manage authentication headers, handle synchronous and asynchronous requests, and process streaming responses (SSE). Crucially, you will explore how to automate these requests to build high-throughput red teaming scripts and robust evaluation harnesses while managing timeouts and API costs.

## Lessons

1. What is the requests Library and Why Testers Use It (30 min)
2. Sending Your First Request to an LLM API (30 min)
3. Handling Responses, Errors and Rate Limits (30 min)
4. Guided Lab: Scripting a Full Request/Response Cycle (30 min)
