OpenRouter, founded in 2023 by OpenSea co-founder Alex Atallah and engineer Louis Vichy, gives a developer one API endpoint, compatible with the OpenAI SDK, to reach more than 400 models across more than 70 providers, Anthropic, OpenAI, Google, Meta among them, rather than building and maintaining a separate integration for each.
Its distributed infrastructure automatically fails over to another provider if one goes down, and custom data policies let an organization control exactly how its requests and outputs are handled across providers, a governance layer most individual model APIs don't offer directly. The platform now processes roughly 25 trillion tokens a week for more than 8 million developers across 250,000-plus applications.
Pricing runs on prepaid credits rather than a flat subscription, with no permanent free tier. For a developer who wants to switch or combine models from different providers through one integration, with automatic failover if a provider has an outage, rather than maintaining separate API keys and code paths per provider, OpenRouter's unified routing layer addresses that directly.
