One field accepts two kinds of Moonshot key, detected from the string itself - and the kind you paste decides the endpoint, the models and the browser path.
Moonshot Supported Models ->Two consoles issue two kinds of Moonshot key, and Big-AGI has one field for both. It works out which kind you pasted from the string itself. That detection decides the endpoint dialled, the models returned, and whether a browser path is offered. No setting overrides it.
platform.moonshot.ai link redirects there.sk-kimi-.A platform account is balance-funded and billed per token, so top up the balance before the first answer. A subscription plan issues a key that exposes that plan's own models. Rates are published in the platform documentation. The enforceable limit is the balance and limits inside whichever console issued the key.
Open Models with Ctrl + Shift + M, press More Services if the Setup AI Models wizard opens, then Add -> Moonshot AI. There is a single key field; press Models afterwards to fetch the list (add and manage your keys).

| anything else | Moonshot API Key | Kimi Platform |
The label tells you what landed. On a subscription key the panel states it outright: "Using your Kimi Code subscription: listing your plan's models on the coding endpoint."
A platform key lets you turn Direct Connection on. A subscription key removes the row entirely: those keys route to a coding endpoint that permits no browser calls, so the request goes through the Big-AGI fast edge servers.
Direct Connection works only with your API key stored in the browser, and with an AI service that permits direct browser calls (CORS). Where it cannot be used, requests route through the Big-AGI fast edge servers instead - everything still works, within the standard upload size and time limits.
