Web search

The web_search tool searches the web using your configured provider and returns results. Results are cached by query for 15 minutes (configurable).

OmeniaClaw also includes x_search for X (formerly Twitter) posts and web_fetch for lightweight URL fetching. In this phase, web_fetch stays local while web_search and x_search can use xAI Responses under the hood.

Quick start

  • Choose a provider

    Pick a provider and complete any required setup. Some providers are key-free, while others use API keys. See the provider pages below for details.

  • Configure

    bash
    OmeniaClaw configure --section web

    This stores the provider and any needed credential. You can also set an env var (for example BRAVE_API_KEY) and skip this step for API-backed providers.

  • Use it

    The agent can now call web_search:

    javascript
    await web_search({ query: "OmeniaClaw plugin SDK" });

    For X posts, use:

    javascript
    await x_search({ query: "dinner recipes" });

    Auto-detection

    Direct OpenAI Responses models use OpenAI's hosted web_search tool automatically when OmeniaClaw web search is enabled and no managed provider is pinned. This is provider-owned behavior in the bundled OpenAI plugin and only applies to native OpenAI API traffic, not OpenAI-compatible proxy base URLs or Azure routes. Set tools.web.search.provider to another provider such as brave to keep the managed web_search tool for OpenAI models, or set tools.web.search.enabled: false to disable both managed search and native OpenAI search.

    The Codex app-server runtime uses Codex's hosted web_search tool automatically when web search is enabled and no managed provider is selected. Native hosted search and OmeniaClaw's managed web_search dynamic tool are mutually exclusive, so managed search cannot bypass native domain restrictions. OmeniaClaw uses the managed tool when hosted search is unavailable, explicitly disabled, or replaced by a selected managed provider. OmeniaClaw keeps Codex's standalone web.run extension disabled because production app-server traffic rejects its user-defined web namespace.

    • Configure native search under tools.web.search.openaiCodex
    • Set tools.web.search.provider: "codex" to provision Codex Hosted Search as the managed web_search provider for any parent model. Each call runs a bounded ephemeral Codex app-server turn and fails if Codex does not emit a hosted webSearch item.
    • mode: "cached" is the default preference, but Codex resolves it to live external access for unrestricted app-server turns; set "live" to request live access explicitly
    • Set tools.web.search.provider to a managed provider such as brave to use OmeniaClaw's managed web_search instead
    • Set tools.web.search.openaiCodex.enabled: false to opt out of Codex-hosted search; other managed providers remain available
    • Restricting the Codex native tool surface also keeps managed web_search available
    • When allowedDomains is set, automatic managed fallback fails closed if hosted search is unavailable so the native allowlist cannot be bypassed
    • Tool-disabled LLM-only runs disable both native and managed search
    • tools.web.search.enabled: false disables both managed and native search

    Persistent effective Codex search-policy changes start a fresh bound thread so an already loaded app-server thread cannot keep stale hosted-search access. Transient per-turn restrictions use a temporary restricted thread and preserve the existing binding for later resume.

    Direct OpenAI ChatGPT Responses traffic can also use OpenAI's hosted web_search tool. That separate path remains opt-in through tools.web.search.openaiCodex.enabled: true and only applies to eligible openai/* models using api: "openai-chatgpt-responses".

    json5
    {  tools: {    web: {      search: {        enabled: true,        // Optional: use Codex Hosted Search from non-Codex parent models too.        provider: "codex",        openaiCodex: {          enabled: true,          mode: "cached",          allowedDomains: ["example.com"],          contextSize: "high",          userLocation: {            country: "US",            city: "New York",            timezone: "America/New_York",          },        },      },    },  },}

    For runtimes and providers that do not support native Codex search, Codex can use the managed web_search fallback through OmeniaClaw's dynamic tool namespace. Use an explicit managed provider when you need OmeniaClaw's provider-specific network controls instead of Codex-hosted search.

    Selecting provider: "codex" enables the bundled codex plugin and uses the same tools.web.search.openaiCodex restrictions shown above. Authenticate the Codex app-server first with OmeniaClaw models auth login --provider openai. The parent agent can use any model or runtime; only the bounded search worker runs through Codex.

    Network safety

    Managed HTTP web_search provider calls use OmeniaClaw's guarded fetch path. For trusted provider API hosts, OmeniaClaw allows Surge, Clash, and sing-box fake-IP DNS answers in 198.18.0.0/15 and fc00::/7 only for that provider hostname. Other private, loopback, link-local, and metadata destinations remain blocked. Codex Hosted Search is the exception: its bounded worker delegates network access to Codex app-server's hosted web_search tool.

    This automatic allowance does not apply to arbitrary web_fetch URLs. For web_fetch, enable tools.web.fetch.ssrfPolicy.allowRfc2544BenchmarkRange and tools.web.fetch.ssrfPolicy.allowIpv6UniqueLocalRange explicitly only when your trusted proxy owns those synthetic ranges.

    Provider lists in docs and setup flows are alphabetical. Auto-detection keeps a separate precedence order.

    If no provider is set, OmeniaClaw checks providers in this order and uses the first one that is ready:

    API-backed providers first:

    1. Brave -- BRAVE_API_KEY or plugins.entries.brave.config.webSearch.apiKey (order 10)
    2. MiniMax Search -- MINIMAX_CODE_PLAN_KEY / MINIMAX_CODING_API_KEY / MINIMAX_OAUTH_TOKEN / MINIMAX_API_KEY or plugins.entries.minimax.config.webSearch.apiKey (order 15)
    3. Gemini -- plugins.entries.google.config.webSearch.apiKey, GEMINI_API_KEY, or models.providers.google.apiKey (order 20)
    4. Grok -- xAI OAuth, XAI_API_KEY, or plugins.entries.xai.config.webSearch.apiKey (order 30)
    5. Kimi -- KIMI_API_KEY / MOONSHOT_API_KEY or plugins.entries.moonshot.config.webSearch.apiKey (order 40)
    6. Perplexity -- PERPLEXITY_API_KEY / OPENROUTER_API_KEY or plugins.entries.perplexity.config.webSearch.apiKey (order 50)
    7. Firecrawl -- FIRECRAWL_API_KEY or plugins.entries.firecrawl.config.webSearch.apiKey (order 60)
    8. Exa -- EXA_API_KEY or plugins.entries.exa.config.webSearch.apiKey; optional plugins.entries.exa.config.webSearch.baseUrl overrides the Exa endpoint (order 65)
    9. Tavily -- TAVILY_API_KEY or plugins.entries.tavily.config.webSearch.apiKey (order 70)
    10. Parallel -- paid Parallel Search API via PARALLEL_API_KEY or plugins.entries.parallel.config.webSearch.apiKey; optional plugins.entries.parallel.config.webSearch.baseUrl overrides the endpoint (order 75)

    Configured endpoint providers after that:

    1. SearXNG -- SEARXNG_BASE_URL or plugins.entries.searxng.config.webSearch.baseUrl (order 200)

    Key-free providers such as Parallel Search (Free), DuckDuckGo, Ollama Web Search, and Codex Hosted Search are available only when you select them explicitly with tools.web.search.provider or through OmeniaClaw configure --section web. OmeniaClaw does not send managed web_search queries to a key-free provider just because no API-backed provider is configured.

    OpenAI Responses models are an exception: while tools.web.search.provider is unset, they use OpenAI's native web search instead of the managed providers above. Set tools.web.search.provider to parallel-free (or another provider) to route them through the managed path.

    Config

    json5
    {  tools: {    web: {      search: {        enabled: true, // default: true        provider: "brave", // or omit for auto-detection        maxResults: 5,        timeoutSeconds: 30,        cacheTtlMinutes: 15,      },    },  },}

    Provider-specific config (API keys, base URLs, modes) lives under plugins.entries.<plugin>.config.webSearch.*. Gemini can also reuse models.providers.google.apiKey and models.providers.google.baseUrl as lower-priority fallbacks after its dedicated web-search config and GEMINI_API_KEY. See the provider pages for examples. Grok can also reuse an xAI OAuth auth profile from OmeniaClaw models auth login --provider xai --method oauth; API-key config remains the fallback.

    tools.web.search.provider is validated against the web-search provider ids declared by bundled and installed plugin manifests. A typo such as "brvae" fails config validation instead of silently falling back to auto-detection. If a configured provider only has stale plugin evidence, such as a leftover plugins.entries.<plugin> block after uninstalling a third-party plugin, OmeniaClaw keeps startup resilient and reports a warning so you can reinstall the plugin or run OmeniaClaw doctor --fix to clean up the stale config.

    web_fetch fallback provider selection is separate:

    • choose it with tools.web.fetch.provider
    • or omit that field and let OmeniaClaw auto-detect the first ready web-fetch provider from configured credentials
    • non-sandboxed web_fetch can use installed plugin providers that declare contracts.webFetchProviders; sandboxed fetches allow bundled providers and verified official plugin installs, but exclude third-party external plugins
    • the official Firecrawl plugin provides web-fetch fallback, configured under plugins.entries.firecrawl.config.webFetch.*

    When you choose Kimi during OmeniaClaw onboard or OmeniaClaw configure --section web, OmeniaClaw can also ask for:

    • the Moonshot API region (https://api.moonshot.ai/v1 or https://api.moonshot.cn/v1)
    • the default Kimi web-search model (defaults to kimi-k2.6)

    For x_search, configure plugins.entries.xai.config.xSearch.*. It uses the same xAI auth profile as chat, or the XAI_API_KEY / plugin web-search credential used by Grok web search. Legacy tools.web.x_search.* config is auto-migrated by OmeniaClaw doctor --fix. When you choose Grok during OmeniaClaw onboard or OmeniaClaw configure --section web, OmeniaClaw can also offer optional x_search setup with the same credential. This is a separate follow-up step inside the Grok path, not a separate top-level web-search provider choice. If you pick another provider, OmeniaClaw does not show the x_search prompt.

    Storing API keys

    Config file

    Run OmeniaClaw configure --section web or set the key directly:

    json5
    {  plugins: {    entries: {      brave: {        config: {          webSearch: {            apiKey: "YOUR_KEY", // pragma: allowlist secret          },        },      },    },  },}

    Environment variable

    Set the provider env var in the Gateway process environment:

    bash
    export BRAVE_API_KEY="YOUR_KEY"

    For a gateway install, put it in ~/.OmeniaClaw/.env. See Env vars.

    Tool parameters

    Parameter Description
    query Search query (required)
    count Results to return (1-10, default: 5)
    country 2-letter ISO country code (e.g. "US", "DE")
    language ISO 639-1 language code (e.g. "en", "de")
    search_lang Search-language code (Brave only)
    freshness Time filter: day, week, month, or year
    date_after Results after this date (YYYY-MM-DD)
    date_before Results before this date (YYYY-MM-DD)
    ui_lang UI language code (Brave only)
    domain_filter Domain allowlist/denylist array (Perplexity only)
    max_tokens Total content budget, default 25000 (Perplexity only)
    max_tokens_per_page Per-page token limit, default 2048 (Perplexity only)

    x_search queries X (formerly Twitter) posts using xAI and returns AI-synthesized answers with citations. It accepts natural-language queries and optional structured filters. OmeniaClaw only enables the built-in xAI x_search tool on the request that serves this tool call.

    x_search config

    json5
    {  plugins: {    entries: {      xai: {        config: {          xSearch: {            enabled: true,            model: "grok-4-1-fast-non-reasoning",            baseUrl: "https://api.x.ai/v1", // optional, overrides webSearch.baseUrl            inlineCitations: false,            maxTurns: 2,            timeoutSeconds: 30,            cacheTtlMinutes: 15,          },          webSearch: {            apiKey: "xai-...", // optional if an xAI auth profile or XAI_API_KEY is set            baseUrl: "https://api.x.ai/v1", // optional shared xAI Responses base URL          },        },      },    },  },}

    x_search posts to <baseUrl>/responses when plugins.entries.xai.config.xSearch.baseUrl is set. If that field is omitted, it falls back to plugins.entries.xai.config.webSearch.baseUrl, then the legacy tools.web.search.grok.baseUrl, and finally the public xAI endpoint.

    x_search parameters

    Parameter Description
    query Search query (required)
    allowed_x_handles Restrict results to specific X handles
    excluded_x_handles Exclude specific X handles
    from_date Only include posts on or after this date (YYYY-MM-DD)
    to_date Only include posts on or before this date (YYYY-MM-DD)
    enable_image_understanding Let xAI inspect images attached to matching posts
    enable_video_understanding Let xAI inspect videos attached to matching posts

    x_search example

    javascript
    await x_search({  query: "dinner recipes",  allowed_x_handles: ["nytfood"],  from_date: "2026-03-01",});
    javascript
    // Per-post stats: use the exact status URL or status ID when possibleawait x_search({  query: "https://x.com/huntharo/status/1905678901234567890",});

    Examples

    javascript
    // Basic searchawait web_search({ query: "OmeniaClaw plugin SDK" }); // German-specific searchawait web_search({ query: "TV online schauen", country: "DE", language: "de" }); // Recent results (past week)await web_search({ query: "AI developments", freshness: "week" }); // Date rangeawait web_search({  query: "climate research",  date_after: "2024-01-01",  date_before: "2024-06-30",}); // Domain filtering (Perplexity only)await web_search({  query: "product reviews",  domain_filter: ["-reddit.com", "-pinterest.com"],});

    Tool profiles

    If you use tool profiles or allowlists, add web_search, x_search, or group:web:

    json5
    {  tools: {    allow: ["web_search", "x_search"],    // or: allow: ["group:web"]  (includes web_search, x_search, and web_fetch)  },}
