About omnirouter

omnirouter provides a single API endpoint that aggregates requests across multiple AI model vendors such as OpenAI, Anthropic, Google, xAI, and DeepSeek. It abstracts provider management, routing, and billing into one interface, allowing teams to switch models without rewriting integrations. The service handles provider failover automatically, selecting the fastest available option for each request and streaming responses in real time. Billing is transparent, with each request charged at the model’s published rate from prepaid credit, and no monthly minimums or subscriptions. API keys are stored securely as hashes, keeping provider credentials out of the application. The platform supports common features like streaming, tool calls, and structured errors, maintaining compatibility with existing OpenAI client libraries. Typical use includes prototyping across models, optimizing costs by routing to cheaper providers, and simplifying vendor management for production workloads.
