Ollama web search

OpenClaw supports Ollama Web Search as a bundled web_search provider, returning titles, URLs, and snippets from Ollama's web-search API.

Local/self-hosted Ollama needs no API key by default; it requires a reachable Ollama host plus ollama signin. Direct hosted search (no local Ollama) needs baseUrl: "https://ollama.com" and a real OLLAMA_API_KEY.

Setup

ollama signin

openclaw configure --section web

If you already use Ollama for models, Ollama Web Search reuses the same configured host.

Config

{  tools: {    web: {      search: {        provider: "ollama",      },    },  },}

Optional host override, scoped to web search only:

{  plugins: {    entries: {      ollama: {        config: {          webSearch: {            baseUrl: "http://ollama-host:11434",          },        },      },    },  },}

Or reuse the host already configured for the Ollama model provider:

{  models: {    providers: {      ollama: {        baseUrl: "http://ollama-host:11434",      },    },  },}

models.providers.ollama.baseUrl is the canonical key; the web-search provider also accepts baseURL there for compatibility with OpenAI SDK-style config examples. If nothing is set, OpenClaw defaults to http://127.0.0.1:11434.

Direct hosted Ollama Web Search (no local Ollama):

{  models: {    providers: {      ollama: {        baseUrl: "https://ollama.com",        apiKey: "OLLAMA_API_KEY",      },    },  },  tools: {    web: {      search: {        provider: "ollama",      },    },  },}

Auth and request routing

• No web-search-specific API key field exists; the provider reuses models.providers.ollama.apiKey (or the matching env-backed provider auth) when the configured host is auth-protected.
• Host resolution order: plugins.entries.ollama.config.webSearch.baseUrl → models.providers.ollama.baseUrl (or baseURL) → http://127.0.0.1:11434.
• If the resolved host is https://ollama.com, OpenClaw calls https://ollama.com/api/web_search directly with the API key as bearer auth.
• Otherwise OpenClaw calls the local proxy endpoint /api/experimental/web_search first (which signs and forwards to Ollama Cloud), then falls back to /api/web_search on the same host. If both fail and OLLAMA_API_KEY is set, it retries once against https://ollama.com/api/web_search with that key — without sending it to the local host.
• OpenClaw warns during setup if Ollama is unreachable or not signed in, but does not block selecting the provider.
