Moonshot AI (Kimi)

Moonshot provides the Kimi API with OpenAI-compatible endpoints. Configure the provider and set the default model to moonshot/kimi-k2.5, or use Kimi Coding with kimi/kimi-code.

WARNING

Moonshot and Kimi Coding are separate providers. Keys are not interchangeable, endpoints differ, and model refs differ (moonshot/... vs kimi/...).

        ],
      },
    },
  },
}

Kimi Coding

Best for: code-focused tasks via the Kimi Coding endpoint.

NOTE

Kimi Coding uses a different API key and provider prefix (kimi/...) than Moonshot (moonshot/...). Legacy model ref kimi/k2p5 remains accepted as a compatibility id.

Run onboarding

openclaw onboard --auth-choice kimi-code-api-key

Set a default model

{
  agents: {
    defaults: {
      model: { primary: "kimi/kimi-code" },
    },
  },
}

Verify the model is available
```
openclaw models list --provider kimi
```

Config example

{
  env: { KIMI_API_KEY: "sk-..." },
  agents: {
    defaults: {
      model: { primary: "kimi/kimi-code" },
      models: {
        "kimi/kimi-code": { alias: "Kimi" },
      },
    },
  },
}

Kimi web search

OpenClaw also ships Kimi as a web_search provider, backed by Moonshot web search.

Run interactive web search setup
```
openclaw configure --section web
```
Choose Kimi in the web-search section to store plugins.entries.moonshot.config.webSearch.*.
Configure the web search region and model
Interactive setup prompts for:
Setting Options
API region https://api.moonshot.ai/v1 (international) or https://api.moonshot.cn/v1 (China)
Web search model Defaults to kimi-k2.5

Setting	Options
API region	`https://api.moonshot.ai/v1` (international) or `https://api.moonshot.cn/v1` (China)
Web search model	Defaults to `kimi-k2.5`

Config lives under plugins.entries.moonshot.config.webSearch:

{
  plugins: {
    entries: {
      moonshot: {
        config: {
          webSearch: {
            apiKey: "sk-...", // or use KIMI_API_KEY / MOONSHOT_API_KEY
            baseUrl: "https://api.moonshot.ai/v1",
            model: "kimi-k2.5",
          },
        },
      },
    },
  },
  tools: {
    web: {
      search: {
        provider: "kimi",
      },
    },
  },
}

Advanced

Native thinking mode

Moonshot Kimi supports binary native thinking:

thinking: { type: "enabled" }
thinking: { type: "disabled" }

Configure it per model via agents.defaults.models.<provider/model>.params:

{
  agents: {
    defaults: {
      models: {
        "moonshot/kimi-k2.5": {
          params: {
            thinking: { type: "disabled" },
          },
        },
      },
    },
  },
}

OpenClaw also maps runtime /think levels for Moonshot:

`/think` level	Moonshot behavior
`/think off`	`thinking.type=disabled`
Any non-off level	`thinking.type=enabled`

WARNING

When Moonshot thinking is enabled, tool_choice must be auto or none. OpenClaw normalizes incompatible tool_choice values to auto for compatibility.

Streaming usage compatibility

Native Moonshot endpoints (https://api.moonshot.ai/v1 and https://api.moonshot.cn/v1) advertise streaming usage compatibility on the shared openai-completions transport. OpenClaw keys that off endpoint capabilities, so compatible custom provider ids targeting the same native Moonshot hosts inherit the same streaming-usage behavior.

Endpoint and model ref reference

Provider	Model ref prefix	Endpoint	Auth env var
Moonshot	`moonshot/`	`https://api.moonshot.ai/v1`	`MOONSHOT_API_KEY`
Moonshot CN	`moonshot/`	`https://api.moonshot.cn/v1`	`MOONSHOT_API_KEY`
Kimi Coding	`kimi/`	Kimi Coding endpoint	`KIMI_API_KEY`
Web search	N/A	Same as Moonshot API region	`KIMI_API_KEY` or `MOONSHOT_API_KEY`

Kimi web search uses KIMI_API_KEY or MOONSHOT_API_KEY, and defaults to https://api.moonshot.ai/v1 with model kimi-k2.5.
Override pricing and context metadata in models.providers if needed.
If Moonshot publishes different context limits for a model, adjust contextWindow accordingly.
