# APIAny.AI > One API to connect everything. APIAny.AI is a unified, OpenAI-compatible API gateway for calling leading AI models — LLM, image, video, and audio — through a single endpoint. Pay-as-you-go prepaid credits that never expire, no subscription. ## Key facts - One OpenAI-compatible API for chat, image, video, and audio generation. - Models include GPT, Claude, Gemini, DeepSeek, Seedance, Kling, MiniMax, Nano Banana, and Suno. - Billing is prepaid credits: $1 = 1000 credits, larger recharges include bonus credits, and credits never expire. - Payment is processed through Stripe as a one-time recharge. There are no subscriptions. - Image and video run as async tasks: you get a task id immediately, poll status or receive a callback, are charged on success, and refunded on failure. - Migration is simple: change the base URL and API key on an existing OpenAI-compatible client. ## Pages - [Models](https://apiany.ai/models): unified model catalog with capabilities and per-model credit pricing. - [Pricing](https://apiany.ai/pricing): credit recharge tiers and bonus rates. - [Collections](https://apiany.ai/collections): model families (GPT, Seedance, Gemini, Veo, and more). - [Docs](https://docs.apiany.ai): API reference, quickstart, and integration guides.
