Flatkey AI
Flatkey AI is a unified AI API gateway that provides a single API key, base URL, and dashboard for accessing multiple AI models from various providers. It eliminates the need for separate provider accounts, scattered API keys, and inconsistent routing by offering a centralized interface for model access, routing, billing, usage analytics, and operational controls. The platform supports an OpenAI-compatible endpoint (https://router.flatkey.ai/v1/chat/completions) and can be integrated with existing tools and coding agents with one-click configuration or quick install scripts. Flatkey claims to be at least 40% cheaper than official model pricing, with a prepaid account balance and metered pay-as-you-go billing. It provides features like intelligent routing with automatic switching and load balancing across multiple upstream accounts to ensure stability and reliability. The dashboard provides real-time visibility into token spend, recharge records, and team usage, enabling quota limits and cost control. Targeted at developers, AI product teams, automation builders, and operations teams, Flatkey simplifies multi-model management for shipping AI features at scale.
