Use Kimi in Claude Code

Steps

1. 1
   Step 1.

   Install Claude Code (native installer, macOS and Linux).

   Terminal

   Copy

   curl -fsSL https://claude.ai/install.sh | bash

2. 2
   Step 2.

   Create an API key on the Kimi Platform (https://platform.kimi.ai/console/api-keys) and use it to replace YOUR_MOONSHOT_API_KEY below.

3. 3
   Step 3.

   Write the following variables into the env field of ~/.claude/settings.json, then restart Claude Code. This example sets the HAIKU tier to kimi-k2.7-code and every other tier to kimi-k3[1m].

   JSON

   Copy

   {
     "env": {
       "ANTHROPIC_BASE_URL": "https://api.moonshot.ai/anthropic",
       "ANTHROPIC_AUTH_TOKEN": "YOUR_MOONSHOT_API_KEY",
       "ANTHROPIC_MODEL": "kimi-k3[1m]",
       "ANTHROPIC_DEFAULT_OPUS_MODEL": "kimi-k3[1m]",
       "ANTHROPIC_DEFAULT_SONNET_MODEL": "kimi-k3[1m]",
       "ANTHROPIC_DEFAULT_HAIKU_MODEL": "kimi-k2.7-code",
       "ANTHROPIC_DEFAULT_FABLE_MODEL": "kimi-k3[1m]",
       "CLAUDE_CODE_SUBAGENT_MODEL": "kimi-k3[1m]",
       "CLAUDE_CODE_AUTO_COMPACT_WINDOW": "1000000",
       "CLAUDE_CODE_EFFORT_LEVEL": "max"
     }
   }

4. 4
   Step 4.

   Check the endpoint and key with curl. A normal JSON response means both work; a 401 means the key is invalid or belongs to a different platform.

   Terminal

   Copy

   curl https://api.moonshot.ai/anthropic/v1/messages \
     --header "Authorization: Bearer YOUR_MOONSHOT_API_KEY" \
     --header "Content-Type: application/json" \
     --data '{"model": "kimi-k3", "max_tokens": 1, "messages": [{"role": "user", "content": "hi"}]}'

5. 5
   Step 5.

   Start Claude Code and enter /status. Base URL should show https://api.moonshot.ai/anthropic and Model should show kimi-k3[1m]. Then send any message (for example hello) to confirm the setup works end to end.
