AI API Aggregation Service

KuaiAPI — a unified AI API gateway for developers

One API key. One endpoint. Access to a curated catalog of leading AI models — GPT, Claude, DeepSeek, Kimi, Grok, and image generation.

KuaiAPI is an AI API aggregation service for developers. We operate a unified API gateway that is fully compatible with the OpenAI and Anthropic SDKs, so you can switch between many models with minimal code changes. We handle authentication, model routing with automatic failover, usage metering, and usage-based billing.

Unified accessOne endpoint and one set of credentials for many models, so you do not manage multiple providers.
Intelligent routingRequests are routed with automatic failover and load balancing for better reliability.
Transparent pricingPer-model, usage-based billing published on our public Model Plaza.
Works with your toolsCompatible with Claude Code, Codex, Cursor and any client that supports a custom Base URL.

Built for developers

Whether you are an individual developer, a startup, or a team building on AI, KuaiAPI gives you one place to access the models you need. Keep your familiar SDK and call logic — just point your Base URL at us and start.
