What is API Stock and what does it offer?

API Stock is one API for generative AI models: chat, video, image and music generation through a single API key and a single prepaid balance. If a model's provider fails a request, the generation automatically moves to a reserve provider — at no extra charge.

What AI models are available on API Stock?

Chat models GPT, Claude, Gemini, DeepSeek, Grok, Qwen, Kimi, GLM; video — Veo 3.1, Kling 3.0, Seedance, Wan; images — Nano Banana, GPT Image, Seedream; music — Suno. The catalog grows regularly: the current list with prices is on the models page.

How does API Stock pricing work?

You pay only for usage: top up your balance and pay per generation or per token — no subscription and no monthly minimums. Every model's price is published upfront on the pricing page, and if a generation fails, its cost is returned to your balance.

How do I integrate API Stock API into my application?

Sign up and create an API key — no credit card required. For chat models the API speaks the OpenAI and Anthropic protocols: in an existing SDK you only change the base_url and the key. Video, image and music are created with a single POST /api/v1/generation/create request, and the result arrives at your webhook or through the task status.
