Master REST API fundamentals and learn to integrate with the most popular LLM APIs in 2025. Build real-world applications using OpenAI, Anthropic, Google Gemini, Mistral, and Groq APIs with proper error handling and streaming support.
Learn the core principles of REST APIs - HTTP methods (GET, POST, PUT, DELETE), headers, request bodies, and response status codes. Understand the foundation that powers all modern web and LLM APIs.
Master integration with 6 major LLM APIs: OpenAI (GPT-4o), Anthropic (Claude 3.5), Google Gemini, Mistral, Groq (fast inference), and Together.ai. Learn best practices for managing API keys with environment variables.
Explore authentication methods for APIs: API keys, OAuth 2.0, and JWT tokens. Learn best practices for securely storing credentials using environment variables, cloud secret managers, and encrypted files.
Build resilient applications that handle API failures gracefully. Implement exponential backoff for rate limits, distinguish between 4xx client errors and 5xx server errors, and use production-ready retry libraries.
Learn to stream API responses in real-time for better user experience. Master Server-Sent Events (SSE) with OpenAI and Anthropic APIs. Display tokens as they're generated, just like ChatGPT.
