This article explains the core prerequisites for connecting Claude Code to Kimi k2.6
Kimi k2.6 is a next-generation model optimized for code generation and agent-based workflows. For developers, the real value is not simply whether it works, but whether it can work reliably through Claude Code’s interaction model.
The most important change today is this: the historical integration approach based on the Moonshot platform no longer applies to Kimi Code. If you continue using endpoints or variable names from older documentation, the most common result will be a 401 error or broken model routing.
There are only three correct integration conclusions
- The Base URL must point to
https://api.kimi.com/coding/. - The API key must be a Kimi Code key that starts with
sk-kimi-. - The explicit model name must be
kimi-for-coding.
# The three core configuration values
export ANTHROPIC_BASE_URL="https://api.kimi.com/coding/" # Point to the Kimi Code endpoint
export ANTHROPIC_API_KEY="sk-kimi-xxxxxxxxxxxxxxxx" # Use a Kimi Code key
export ANTHROPIC_MODEL="kimi-for-coding" # Specify the real model IDThis configuration determines where Claude Code sends requests, which credentials it uses for authentication, and which model it ultimately calls.
The environment must satisfy Claude Code runtime requirements before installation
If Claude Code is not installed on your machine yet, start by preparing Node.js and the official CLI. On macOS and Linux, use a recent Node.js 24.x release. On Windows, you can install it directly with winget.
# Install Node.js and Claude Code
curl -fsSL https://fnm.vercel.app/install | bash
fnm install 24.3.0
fnm default 24.3.0
npm install -g @anthropic-ai/claude-code
# Skip the first-run onboarding to avoid interactive blocking
node --eval '
const os = require("os"); // Read the user home directory
const fs = require("fs"); // Read and write config files
const path = require("path"); // Build file paths
const fp = path.join(os.homedir(), ".claude.json");
const c = fs.existsSync(fp) ? JSON.parse(fs.readFileSync(fp)) : {};
fs.writeFileSync(fp, JSON.stringify({ ...c, hasCompletedOnboarding: true }, null, 2));
'This script installs the CLI and initializes Claude Code’s local configuration state.
After installation, confirm that the version meets the requirement.
claude --version # Verify that Claude Code is installed and executableThis step confirms that the local CLI is installed correctly and ready for configuration.
You must distinguish Kimi Code from the Moonshot platform when creating an API key
Create the API key in the Kimi Code console instead of reusing an old key from the Moonshot Open Platform. Although both belong to the Moonshot AI ecosystem, their authentication systems are separate and cannot be mixed.
AI Visual Insight: The image shows the API key creation entry in the Kimi Code console. The key takeaway is that developers must generate a key starting with sk-kimi-. This key is valid only for the api.kimi.com/coding/ endpoint, not for Moonshot’s general open platform API.
If you use an sk-kimi- key against api.moonshot.cn, the server will typically return an invalid authentication error. That does not mean the key is expired. It means the endpoint and credential system do not match.
It helps to build a minimal mental model first
api.kimi.com/coding/: for Kimi Code.sk-kimi-...: for Kimi Code authentication.api.moonshot.cn: not part of the integration path covered in this article.
Writing environment variables into your shell is the most direct integration method
For most terminal users, the simplest method is to write the environment variables into ~/.zshrc, ~/.bashrc, or ~/.bash_profile. After you open a new terminal session, Claude Code will load the configuration automatically.
# Recommended configuration for Claude Code + Kimi k2.6
export ANTHROPIC_BASE_URL="https://api.kimi.com/coding/" # Kimi Code compatible endpoint
export ANTHROPIC_API_KEY="sk-kimi-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" # Replace with your real key
export ANTHROPIC_MODEL="kimi-for-coding" # Primary model
export ANTHROPIC_DEFAULT_OPUS_MODEL="kimi-for-coding" # Map Opus
export ANTHROPIC_DEFAULT_SONNET_MODEL="kimi-for-coding" # Map Sonnet
export ANTHROPIC_DEFAULT_HAIKU_MODEL="kimi-for-coding" # Map Haiku
export CLAUDE_CODE_SUBAGENT_MODEL="kimi-for-coding" # Use one model for sub-agents
export ENABLE_TOOL_SEARCH="false" # Disable unnecessary search capabilityThese variables map Claude Code’s multiple model entry points to Kimi’s actual available model.
Then reload the shell configuration.
source ~/.zshrc # Reload the shell configurationThis step makes the current terminal session load the newly added environment variables immediately.
Writing settings.json improves reliability in GUI and multi-entry scenarios
Relying only on shell environment variables is not always reliable. If Claude Code starts from a GUI, IDE, or another non-login shell context, the environment variables may not be inherited automatically. For that reason, it is best to also write the same configuration into ~/.claude/settings.json.
mkdir -p ~/.claude # Make sure the config directory exists
cat > ~/.claude/settings.json << 'EOF'
{
"skipDangerousModePermissionPrompt": true,
"env": {
"ANTHROPIC_BASE_URL": "https://api.kimi.com/coding/",
"ANTHROPIC_API_KEY": "sk-kimi-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"ANTHROPIC_MODEL": "kimi-for-coding",
"ANTHROPIC_DEFAULT_OPUS_MODEL": "kimi-for-coding",
"ANTHROPIC_DEFAULT_SONNET_MODEL": "kimi-for-coding",
"ANTHROPIC_DEFAULT_HAIKU_MODEL": "kimi-for-coding",
"CLAUDE_CODE_SUBAGENT_MODEL": "kimi-for-coding",
"ENABLE_TOOL_SEARCH": "false"
}
}
EOF
chmod 600 ~/.claude/settings.json # Prevent other users from reading the keyThis command sequence creates the user-level Claude Code configuration file and protects the key so that only the current user can read it.
You must verify success through both the status page and actual request behavior
First, verify that the variables exist. Then start Claude Code inside a project directory. Looking only at the configuration file is not enough. You need to verify runtime behavior as well.
env | grep ANTHROPIC # Check whether the key environment variables are loaded
cd ~/your-project # Enter any project directory
claude # Launch Claude CodeThese commands confirm that the configuration was injected successfully and start the interactive environment.
Once inside, run /status. If the interface shows the Kimi-specific base URL and model values, the routing is configured correctly.
AI Visual Insight: The image shows Claude Code’s status page. The key observation is that the underlying connection information has switched to a custom Anthropic-compatible backend, which lets developers verify that the base URL, model name, and runtime environment match the Kimi configuration.
Then send a normal request, such as asking Claude Code to inspect the project directory structure. If token usage appears in the status bar, that is a strong sign that the model has responded successfully.
AI Visual Insight: The image shows Claude Code in a normal conversation state. The token usage at the bottom and the generated output indicate that the backend model has processed the request successfully, which means authentication, routing, and model invocation are all working.
Most common failures fall into three categories: endpoint, model name, and network
The wrong endpoint causes 401 authentication failures
If you use api.moonshot.cn/anthropic, you may receive 401 Invalid Authentication even if the API key looks valid. In most cases, the root cause is not an expired key. It is the wrong platform endpoint.
export ANTHROPIC_BASE_URL="https://api.kimi.com/coding/" # Switch to the correct endpoint
export ANTHROPIC_API_KEY="sk-kimi-xxxxxxxxxxxxxxxx" # Use a Kimi Code keyThis fix restores the correct authentication path.
The wrong model name causes 404 model_not_found
The real model identifier for Kimi k2.6 is not kimi-k2.6. It is kimi-for-coding. If you explicitly set the wrong model name, Claude Code will fail to find the resource when it sends the request.
curl -s https://api.kimi.com/coding/v1/models \
-H "Authorization: Bearer $ANTHROPIC_API_KEY" | jq '.data[].id' # List the model IDs available from the serverThis command lets you confirm directly from the server which model IDs are visible to your current account.
If the configuration is correct but requests still hang, check the network and version
A normal /status page does not guarantee that the entire request path is healthy. If requests hang for a long time after submission, first check network connectivity, account quota, and the Claude Code version.
curl -I https://api.kimi.com/coding/v1/models # Test API reachability
npm install -g @anthropic-ai/claude-code # Upgrade Claude Code to the latest versionThese commands verify API connectivity and eliminate client compatibility issues caused by outdated versions.
The conclusion is that connecting Claude Code to Kimi k2.6 depends on following the new API contract
The essence of this approach is not to modify Claude Code in some unsupported way. It is to make Claude Code send requests to the Kimi Code backend through an Anthropic-compatible interface. As long as the endpoint, authentication variables, and model ID are all correct, Claude Code can serve as a stable frontend for Kimi k2.6.
For developers, the most important thing to remember is not the entire command set, but this minimal formula: api.kimi.com/coding/ + sk-kimi- + kimi-for-coding. If you match these three values correctly, most problems disappear on their own.
The FAQ section answers the most common troubleshooting questions
Q1: Why does Claude Code still return 401 even though I already have a Kimi key?
A: The most common reason is that you sent an sk-kimi- key to api.moonshot.cn. Kimi Code and the Moonshot Open Platform use separate authentication systems, so you must switch to https://api.kimi.com/coding/.
Q2: Can I set ANTHROPIC_MODEL to kimi-k2.6?
A: No. When you configure the model explicitly, use kimi-for-coding. kimi-k2.6 is a product name, not the API model ID for this integration scenario.
Q3: Why does /status look normal, but messages never get a response?
A: Check three things first: whether api.kimi.com is reachable, whether your account still has available quota, and whether Claude Code has been upgraded to version 2.1.x or later.
