LLM API Interaction (OpenAI, Anthropic)
Understand how to programmatically interact with leading LLM providers like OpenAI and Anthropic using their official APIs.
Why Use LLM APIs?
Large Language Models (LLMs) like those from OpenAI and Anthropic are incredibly powerful. To use them in your own apps, you need to interact with their Application Programming Interfaces (APIs).
An API acts like a messenger, allowing your code to send requests to the LLM and receive its responses. This enables you to build dynamic, AI-powered features into your applications.
API Keys: Your Access Pass
To use an LLM API, you need an API key. Think of it as a password that authenticates your requests and links them to your account for billing.
- Get your key: Sign up on OpenAI or Anthropic's platform and generate an API key.
- Keep it secret: Never hardcode your API key directly in your code. Store it securely, ideally as an environment variable.
- Environment variables: These are system-wide variables that your program can access without the key being visible in the code itself.
