- Constructor Detail
- Method Detail
  - _name
```
 final JsonValue _name()
```
    Name of the tool.
    This is how the tool will be called by the model and in tool_use blocks.
    Expected to always return the following:
    JsonValue.from("web_fetch")
    However, this method can be useful for debugging and logging (e.g. if the server responded with an unexpected value).
  - _type
```
 final JsonValue _type()
```
    Expected to always return the following:
    JsonValue.from("web_fetch_20260309")
    However, this method can be useful for debugging and logging (e.g. if the server responded with an unexpected value).
  - allowedCallers
```
 final Optional<List<WebFetchTool20260309.AllowedCaller>> allowedCallers()
```
  - allowedDomains
```
 final Optional<List<String>> allowedDomains()
```
    List of domains to allow fetching from
  - blockedDomains
```
 final Optional<List<String>> blockedDomains()
```
    List of domains to block fetching from
  - cacheControl
```
 final Optional<CacheControlEphemeral> cacheControl()
```
    Create a cache control breakpoint at this content block.
  - citations
```
 final Optional<CitationsConfigParam> citations()
```
    Citations configuration for fetched documents. Citations are disabled by default.
  - deferLoading
```
 final Optional<Boolean> deferLoading()
```
    If true, tool will not be included in initial system prompt. Only loaded when returned via tool_reference from tool search.
  - maxContentTokens
```
 final Optional<Long> maxContentTokens()
```
    Maximum number of tokens used by including web page text content in the context. The limit is approximate and does not apply to binary content such as PDFs.
  - maxUses
```
 final Optional<Long> maxUses()
```
    Maximum number of times the tool can be used in the API request.
  - strict
```
 final Optional<Boolean> strict()
```
    When true, guarantees schema validation on tool names and inputs
  - useCache
```
 final Optional<Boolean> useCache()
```
    Whether to use cached content. Set to false to bypass the cache and fetch fresh content. Only set to false when the user explicitly requests fresh content or when fetching rapidly-changing sources.

    Unlike citations, this method doesn't throw if the JSON field has an unexpected type.
  - _deferLoading
```
 final JsonField<Boolean> _deferLoading()
```
    Returns the raw JSON value of deferLoading.
    Unlike deferLoading, this method doesn't throw if the JSON field has an unexpected type.
  - _maxContentTokens
```
 final JsonField<Long> _maxContentTokens()
```
