Hear from developers who simplified their AI integrations with ApiAny.
David Chen
Backend Engineer
ApiAny's unified API saved us weeks of integration work. We switched from 3 separate provider SDKs to one API key.
Rachel Kim
CTO, AI Startup
The auto-failover is incredible. When OpenAI had an outage, our app kept running on Gemini without any manual intervention.
Marcus Thompson

What is ApiAny?
ApiAny is an API aggregation proxy that connects to multiple AI providers (OpenAI, Gemini, Claude, DeepSeek, etc.) and provides a unified OpenAI-compatible API. It handles routing, failover, billing, and analytics automatically.
Is it compatible with OpenAI SDK?
Yes! ApiAny provides a fully OpenAI-compatible API. Just change the base URL and API key in your existing code — no other changes needed. Works with the official OpenAI SDK in Python, Node.js, and all other languages.
What AI models are supported?
ApiAny supports GPT-4o, GPT-4.1, Claude Sonnet/Haiku, Gemini 2.5 Flash/Pro, DeepSeek V3/R1, DALL-E 3, Gemini Image Generation, Sora 2, Veo 3, and more. New models are added regularly.
How does billing work?
Chat models are billed by token usage (input + output) with a minimum per-request charge. Image and video models are billed per request. User groups can have different rate multipliers (e.g., free users pay 2x, enterprise pays 0.8x).
What happens when a provider goes down?
ApiAny automatically fails over to the next channel in the fallback chain. Each model has multiple provider groups configured with weights. If Group 1 fails, it tries Group 2, then Group 3, ensuring high availability.
Can I track usage per API key?
Yes. Each user can create multiple API keys. All usage is tracked per-key with detailed statistics including request count, token usage, credits consumed, upstream costs, and error rates.
