Cloud Api Integration

This is for integrating Claude, GPT-4, and Gemini APIs into your applications with actual security guardrails. It covers the stuff that bites you in production: secure API key management and rotation, prompt injection prevention, rate limiting to avoid bill shock, and multi-provider fallback when one service goes down. The implementation examples are TDD-focused with mocked API calls, connection pooling, exponential backoff retries, and response caching. Marked as high risk because you're handling credentials and untrusted prompts. Use this when you need cloud AI capabilities but can't afford to leak keys, get exploited by prompt injection, or blow your API budget on a runaway loop.
