OpenRouter

OpenRouter is an API platform that provides unified access to multiple AI language models through a single interface. OpenRouter acts as a "router" or gateway that lets developers and applications access dozens of different AI models from various providers through one standardized API, rather than having to integrate with each provider separately.

OpenRouter publishes 7 APIs on the APIs.io network, including Chat API, Completions API, Credits API, and 4 more. Tagged areas include Artificial Intelligence, Gateway, Large Language Models, and Router.

The OpenRouter catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

OpenRouter’s developer surface includes authentication, getting-started guide, FAQ, pricing, developer portal, documentation, support, and 37 more developer resources.
