The secondary sources disagree with the primary one. The difference matters if you are choosing how to pay for model access.
Subscription vs API key
A consumer subscription and a developer API key are different products with different terms. Third-party tools that ask you to paste a subscription session are not the same as pointing an SDK at an OpenAI-compatible base URL with a scoped key. Read the provider's own terms before you trust a blog that summarizes them.
Supesonic issues its own API keys. You do not paste a consumer subscription into the console. Create a key in API keys.
