Kimi is a web_search provider backed by Moonshot’s native web search. Moonshot synthesizes one answer with inline citations, similar to Gemini and Grok’s grounded-response providers, rather than returning a ranked result list.

​
Setup

1

Create a key

Get an API key from Moonshot AI.
2

Store the key

Set KIMI_API_KEY or MOONSHOT_API_KEY in the Gateway environment (for a gateway install, add it to ~/.openclaw/.env), or configure via:
openclaw configure --section web
Choosing Kimi during openclaw onboard or openclaw configure --section web also prompts for:
  • the Moonshot API region: https://api.moonshot.ai/v1 or https://api.moonshot.cn/v1
  • the web-search model (defaults to kimi-k2.6)

​
Config

{
  plugins: {
    entries: {
      moonshot: {
        config: {
          webSearch: {
            apiKey: "sk-...", // optional if KIMI_API_KEY or MOONSHOT_API_KEY is set
            baseUrl: "https://api.moonshot.ai/v1",
            model: "kimi-k2.6",
          },
        },
      },
    },
  },
  tools: {
    web: {
      search: {
        provider: "kimi",
      },
    },
  },
}
tools.web.search.provider is auto-detected from available API keys when omitted; set it to kimi explicitly if multiple search credentials are configured. Equivalent scoped form under tools.web.search.kimi (apiKey, baseUrl, model) also works; both shapes merge into the same resolved config. Defaults: baseUrl defaults to https://api.moonshot.ai/v1 when omitted, model defaults to kimi-k2.6. If chat traffic uses the China host (models.providers.moonshot.baseUrl: https://api.moonshot.cn/v1), Kimi web_search reuses that host automatically when its own baseUrl is unset, so .cn keys do not accidentally hit the international endpoint (which returns HTTP 401 for those keys). Set an explicit Kimi baseUrl to override this inheritance.

​
Grounding requirement

OpenClaw only returns a Kimi web_search result after Moonshot’s response includes native web-search grounding evidence, such as a $web_search tool-call replay, search_results, or citation URLs. If Kimi answers directly with no grounding (for example “I cannot browse the internet”), OpenClaw returns a kimi_web_search_ungrounded error instead of treating that text as a search result. Retry the query, switch to a structured provider such as Brave, or use web_fetch / the browser tool when you already have a target URL.
