FAQ

What is API in One and what does it offer?

API in One is a unified AI API platform for accessing live chat, image, video, audio, and tool model routes through a single API key, shared balance, and consistent billing console.

What AI models are available on API in One?

API in One includes model routes such as Gemini, Flux, GPT Image, Imagen, Kling, Wan, Hailuo, PixVerse, Suno, and ElevenLabs, all accessible through one unified API surface.

How does pricing compare to other API providers?

API in One shows each live model route with its credit cost and approximate USD value. Account top-up, orders, and credit balance continue through the shared dashboard.

How do I integrate the API in One API into my application?

Simple integration: 1) create an API key in the shared dashboard, 2) update your base_url to API in One's endpoint, 3) start using the OpenAI-compatible request format where supported.

Why should I choose API in One over using model providers directly?

With API in One, you manage one account, one API key, one balance, and one billing path across supported model providers.

What programming languages are supported?

API in One works with any language that can make HTTPS requests. The docs include examples for cURL, Python, JavaScript, Go, Java, and PHP.

Are API keys secure and how should I use them?

Keep API keys in backend environment variables and call API in One from your server routes. Do not expose production keys in browser-side code.

Top-up, orders, credit balance, and account pages continue through the shared dashboard. Contact support for enterprise purchasing, invoices, and higher-volume usage requirements.

Are requests used to train models?

API in One routes requests to model providers according to each model pipeline. Avoid sending sensitive data unless your internal compliance review approves the provider and model.
