I think what you meant is "you aren't allowed to expose the access to the API to end users", which is a fair condition IMHO.
You're still allowed to expose the functionality (ie. build a SaaS or AI assistant powered by OpenRouter API), just don't build a proxy.
To be clear, I like Openrouter and recommend it to many people (I don't aim to "shit on it").
It does talk about a competing service, if I build a service that propose all the image gen models of Openrouter, and charge the user for it per token, am I allowed?
