爱次元API (AiCy API) is an AI gateway service that aggregates multiple large language models under a unified interface. It offers OpenAI-compatible protocols, allowing developers to switch between models like GPT, Claude, Gemini, and Grok by simply changing the base URL and API key.
Key capabilities:
- Unified model access with consistent API interfaces
- Stable routing optimized for CLI and streaming outputs
- Cost control with transparent usage tracking
- Native tool support for Claude Code, CodeX, and Gemini CLI
- Third-party client integration guides for desktop and mobile
Typical use cases include development workflows, long conversations, batch tasks, and cost-managed AI deployments. The service emphasizes reduced migration effort and consistent governance from proof-of-concept to production.
