What is OpenRouter?

OpenRouter gives developers and teams a shared API for accessing AI models from multiple providers. Its catalog includes models for text, images, video, and audio, with both a browser-based chat interface and API access. The API is OpenAI-compatible, allowing applications built around that interface to connect through an OpenRouter API key.

Users create an account, purchase credits for paid usage, and choose models or providers for their requests. Routing options include preferred providers, automatic routing, and fallback to another provider when one becomes unavailable. Paid plans also include prompt caching, budgets, spending controls, activity logs, and data-policy routing to restrict which models and providers receive prompts.

The free plan offers a smaller selection of models and providers, limited to 50 requests per day. Standard and Business use pay-as-you-go billing with different platform fees rather than fixed monthly subscriptions. Business adds US and EU regional routing, advanced notifications, and more workspaces. Enterprise offers additional controls such as SSO/SAML, managed policy enforcement, contractual service levels, and optional private endpoints.

What can OpenRouter do?

  • Unified model API

  • Provider routing and fallback

  • Multimodal model access

  • Budgets and usage tracking

    Track activity, export logs, and apply budgets and spending controls on paid plans.

  • Data-policy routing

    Restrict requests to models and providers that meet your organization's data policies.

  • Regional and enterprise controls

    Business adds US and EU routing; Enterprise adds SSO/SAML, policy enforcement, and contractual service levels.
