237237 Web search is enabled for your organization unless an administrator has disabled it in the [Claude Console](https://platform.claude.com/settings/privacy), where they can also restrict which domains it searches. If it's disabled, a request that includes the tool fails with a 400 `invalid_request_error` that says web search is not enabled, rather than an [error code](https://platform.claude.com/docs/en/agents-and-tools/tool-use/web-search-tool#errors) inside a search result.

240These organization-level settings in the Claude Console apply to Messages API requests only. [Claude Managed Agents](https://platform.claude.com/docs/en/managed-agents/overview) sessions use only the per-tool `allowed_domains` and `blocked_domains` lists on the agent toolset; see [Restrict web search and web fetch domains](https://platform.claude.com/docs/en/managed-agents/tools#restrict-web-search-and-web-fetch-domains).

451455The `user_location` parameter allows you to localize search results based on a user's location. Provide at least one of `city`, `region`, `country`, or `timezone`.
from line 459
455459* `region`: The region or state
456460* `country`: The two-letter [ISO 3166-1 alpha-2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) country code. The API rejects unsupported country codes with a 400 error.
457461* `timezone`: The [IANA timezone ID](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones).
462
463On Claude Managed Agents, the `web_search` entry of the agent toolset accepts a `user_location` object with the same fields. The API rejects an unsupported `country` code with a 400 error when you create or update the agent, or when you create or update a session that supplies the setting. See [Restrict web search and web fetch domains](https://platform.claude.com/docs/en/managed-agents/tools#restrict-web-search-and-web-fetch-domains).
