Llama 3.1 70B API access?

I see “You have been granted access to this model” on the page for Llama 3.1 70B, and the test widget works; but when I try to access it through a third-party app, or make a test API call through curl, I get the error “Model not supported by provider featherless-ai”. The same call works fine for other models. Why is that, and how can I access Llama outside the tester?
