LLM APIs and SDKs skills for Claude Code and Codex
Skills for calling model providers directly: the Gemini API and Live API, OpenAI documentation, Amazon Bedrock, Firebase AI Logic, Venice's OpenAI-compatible endpoints, Replicate model search and comparison, and AI gateways on Azure and Neon that put many models behind one credential. They give an agent the current request shapes, limits and error handling for each provider.

How to choose LLM API skills
Use the provider's own skill for the API you call. Google, OpenAI, AWS, Firebase and Venice publish skills that track their current endpoints, which matters when model names and parameters change often.
Every skill here reads an API key or cloud credential, listed under Before you install. Keep keys in environment variables and give each app its own key.
If you route across several providers, a gateway skill (azure-aigateway, neon-ai-gateway) centralizes keys, rate limits and caching in one place instead of in each app.
