API Reference
Use this page as the entry point for OmniRouters API documentation. OmniRouters provides unified access to multimodal AI capabilities such as chat, image, video, speech, music, embeddings, and rerank.
The complete endpoint catalogue is maintained in Apifox. This site provides the onboarding path, integration notes, and links to the full reference.
LLM Text Generation
If you are integrating chat, text generation, or reasoning workflows, start with the dedicated LLM protocol pages:
- LLM Text Generation overview
- OpenAI Chat Completions
- OpenAI Responses
- Claude Messages
- Gemini Generate Content
- Protocol Comparison
OmniRouters supports OpenAI-compatible requests across all enabled models. If you are unsure which protocol to use, start with OpenAI-compatible routes first.
Video and Image Generation
If you are integrating text-to-video, image-to-video, image generation, or reference-image workflows, start with these pages:
- Omni-Video API: compatible video creation routes, minimal text-to-video/image-to-video examples, and top-level request fields.
- Omni-Image API: standard image generation, minimal reference-to-image examples, and top-level request fields.
