How an agent gets a LongCat key through KeyKeeper, what to choose on longcat.chat, and how KeyKeeper verifies it.

Template id	`longcat` (also `LongCat AI`)
Field	`longcat-api-key` → `LONGCAT_API_KEY` · secret
Key looks like	shown once when created
Created at	longcat.chat
Verified by KeyKeeper	not verified
Template checked	2026-09-15

What the agent does

keykeeper providers show longcat
keykeeper save --provider longcat --from-clipboard --create --purpose "what this task does"
keykeeper run -c longcat -- <your command>

--provider longcat fills in the credential id and the field. The environment variable is the one LongCat's own tools read, so nothing has to be mapped.

What to choose

官方快速开始未规定默认环境变量；LONGCAT_API_KEY 只是 KeyKeeper 的本地注入名，客户端必须显式读取或配置它。

The agent is told the same thing. It opens the page for you and says what to pick; it never logs in, passes 2FA or pays on your behalf.

What KeyKeeper checks

Before writing: the value must look like a LongCat key (shown once when created). A wrong paste is refused before anything is stored, and the agent is told why — without the value.
After saving: LongCat offers no read-only endpoint KeyKeeper can use, so the first real call is the test.

Endpoints

The key is a bearer token for these endpoints. keykeeper run sets only the variables above; point your client at the base URL yourself.
