Integrating multiple AI providers usually means multiple SDKs, keys and invoices. An OpenAI-compatible gateway changes that: one prepaid key, one base URL, and access to GPT-class, Claude-class, Gemini-class, DeepSeek and open-source models.

KeyoAPI gives developers a single endpoint for text, image, voice and video APIs. The OpenAI API pricing on KeyoAPI is published per model and starts at $0.01 per million tokens, so you can switch models without switching infrastructure — just keep your OpenAI SDK and change the base URL.
