Integrating AI APIs into Your Applications

Learn to use OpenAI, Anthropic, and Google AI APIs to add intelligence to your own apps.

In this guide (5 steps):

~15s

Sign up at platform.openai.com, console.anthropic.com, or ai.google.dev. Generate an API key and store it securely — never in client-side code.

~15s

Use the REST API or official SDKs (Python, JavaScript). A simple completion request sends a prompt and receives generated text back.

~15s

For chat interfaces, use streaming to show tokens as they're generated instead of waiting for the full response. Better user experience.

~15s

Set usage limits, use cheaper models for simple tasks, cache common responses, and monitor your spending through the provider's dashboard.

~15s

Handle rate limits (429 errors) with exponential backoff. Handle timeouts gracefully. Always have fallback behavior when the API is unavailable.
