This response is received in the [WebFetchPostToolUsePayload](https://ai.easyaf.dev/claudeessentials/api-reference/CloudNimble/ClaudeEssentials/Hooks/Tools/WebFetchPostToolUsePayload.md) when the `tool_name` is "WebFetch". Key features of the WebFetch tool: * HTTP URLs are automatically upgraded to HTTPS * Content is converted from HTML to markdown for easier processing * Large content may be summarized or truncated * Includes a 15-minute cache for repeated requests to the same URL * Redirects to different hosts are reported rather than followed automatically Example JSON payload: ```csharp theme={null} { "url": "https://docs.anthropic.com/claude-code", "content": "# Claude Code Documentation\n\nClaude Code is a CLI tool...", "durationSeconds": 1.25, "truncated": false } ``` ## Constructors ### .ctor #### Syntax ```csharp theme={null} public WebFetchToolResponse() ``` ### .ctor Inherited > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public Object() ``` ## Properties ### Bytes Gets or sets the number of bytes in the raw response body before processing. #### Syntax ```csharp theme={null} public System.Nullable Bytes { get; set; } ``` #### Property Value Type: `System.Nullable?` #### Remarks This indicates the size of the original content fetched from the URL before any markdown conversion or summarization was applied. This property may be `null` for older-style responses that do not include byte-level metrics. ### Code Gets or sets the HTTP status code returned by the server. #### Syntax ```csharp theme={null} public System.Nullable Code { get; set; } ``` #### Property Value Type: `System.Nullable?` #### Remarks Common values include `200` (OK), `301` (Moved Permanently), `404` (Not Found), etc. This property may be `null` for older-style responses that do not include the HTTP status code. ### CodeText Gets or sets the HTTP status text corresponding to [WebFetchToolResponse.Code](https://ai.easyaf.dev/claudeessentials/api-reference/CloudNimble/ClaudeEssentials/Hooks/Tools/Responses/WebFetchToolResponse.md#code). #### Syntax ```csharp theme={null} public string CodeText { get; set; } ``` #### Property Value Type: `string?` #### Remarks For example, `"OK"` for a 200 response or `"Moved Permanently"` for a 301 redirect. This property may be `null` for older-style responses that do not include the HTTP status text. ### Content Gets or sets the processed content from the fetched URL. #### Syntax ```csharp theme={null} public string Content { get; set; } ``` #### Property Value Type: `string` #### Remarks The content is the result of processing the URL with the prompt specified in [WebFetchToolInput.Prompt](https://ai.easyaf.dev/claudeessentials/api-reference/CloudNimble/ClaudeEssentials/Hooks/Tools/Inputs/WebFetchToolInput.md#prompt). HTML content is converted to markdown before processing. If the content was very large, it may have been summarized by the processing model. Check [WebFetchToolResponse.Truncated](https://ai.easyaf.dev/claudeessentials/api-reference/CloudNimble/ClaudeEssentials/Hooks/Tools/Responses/WebFetchToolResponse.md#truncated) to determine if truncation occurred. ### DurationMs Gets or sets the duration of the fetch and processing operation in milliseconds. #### Syntax ```csharp theme={null} public System.Nullable DurationMs { get; set; } ``` #### Property Value Type: `System.Nullable?` #### Remarks This includes the time taken to fetch the URL content, convert HTML to markdown, and process the content with the specified prompt. This property may be `null` when duration information is not available. ### DurationSeconds Gets or sets the duration of the fetch and processing operation in seconds. #### Syntax ```csharp theme={null} public System.Nullable DurationSeconds { get; set; } ``` #### Property Value Type: `System.Nullable?` #### Remarks This includes the time taken to: Cached responses (within the 15-minute cache window) will typically be faster. ### RedirectUrl Gets or sets the redirect URL if the fetch resulted in a redirect to a different host. #### Syntax ```csharp theme={null} public string RedirectUrl { get; set; } ``` #### Property Value Type: `string?` #### Examples ```csharp theme={null} // Original URL: https://short.link/abc // Redirect URL: https://example.com/full-article ``` #### Remarks When a URL redirects to a different host (domain), the WebFetch tool does not automatically follow the redirect. Instead, it reports the redirect URL here so that a new fetch request can be made explicitly. This behavior provides transparency about where content is coming from and prevents unexpected cross-domain requests. If no cross-host redirect occurred, this property will be `null`. Same-host redirects (e.g., HTTP to HTTPS on the same domain) are followed automatically. ### Result Gets or sets the processed result text from the fetched URL. #### Syntax ```csharp theme={null} public string Result { get; set; } ``` #### Property Value Type: `string?` #### Remarks This is the result of processing the URL content with the prompt. In newer response schemas, this field is used instead of [WebFetchToolResponse.Content](https://ai.easyaf.dev/claudeessentials/api-reference/CloudNimble/ClaudeEssentials/Hooks/Tools/Responses/WebFetchToolResponse.md#content). ### Truncated Gets or sets a value indicating whether the content was truncated due to size limits. #### Syntax ```csharp theme={null} public System.Nullable Truncated { get; set; } ``` #### Property Value Type: `System.Nullable?` #### Remarks When `true`, the original content exceeded the maximum size and was truncated or summarized. The [WebFetchToolResponse.Content](https://ai.easyaf.dev/claudeessentials/api-reference/CloudNimble/ClaudeEssentials/Hooks/Tools/Responses/WebFetchToolResponse.md#content) will contain a condensed version of the information. For very large pages, consider using a more specific prompt in [WebFetchToolInput.Prompt](https://ai.easyaf.dev/claudeessentials/api-reference/CloudNimble/ClaudeEssentials/Hooks/Tools/Inputs/WebFetchToolInput.md#prompt) to extract only the relevant information. ### Url Gets or sets the URL that was fetched. #### Syntax ```csharp theme={null} public string Url { get; set; } ``` #### Property Value Type: `string` #### Remarks This is the actual URL that was requested. If the original URL used HTTP, it will have been upgraded to HTTPS. If a redirect occurred to a different host, this will still show the original URL, and [WebFetchToolResponse.RedirectUrl](https://ai.easyaf.dev/claudeessentials/api-reference/CloudNimble/ClaudeEssentials/Hooks/Tools/Responses/WebFetchToolResponse.md#redirecturl) will contain the redirect destination. ## Methods ### Equals Inherited Virtual > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public virtual bool Equals(object obj) ``` #### Parameters | Name | Type | Description | | - | - | - | | `obj` | `object?` | - | #### Returns Type: `bool` ### Equals Inherited > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public static bool Equals(object objA, object objB) ``` #### Parameters | Name | Type | Description | | - | - | - | | `objA` | `object?` | - | | `objB` | `object?` | - | #### Returns Type: `bool` ### GetHashCode Inherited Virtual > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public virtual int GetHashCode() ``` #### Returns Type: `int` ### GetType Inherited > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public System.Type GetType() ``` #### Returns Type: `System.Type` ### MemberwiseClone Inherited > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} protected internal object MemberwiseClone() ``` #### Returns Type: `object` ### ReferenceEquals Inherited > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public static bool ReferenceEquals(object objA, object objB) ``` #### Parameters | Name | Type | Description | | - | - | - | | `objA` | `object?` | - | | `objB` | `object?` | - | #### Returns Type: `bool` ### ToString Inherited Virtual > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public virtual string ToString() ``` #### Returns Type: `string?` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
