## Parameters
| Parameter | Type | Required | Default | Range | Description |
| ---------------- | ------- | -------- | ----------------- | ------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `model` | string | ✅ Yes | `claude-opus-4-6` | - | The model identifier. Use `claude-opus-4-6` for this model |
| `messages` | array | ✅ Yes | - | - | Input messages for the conversation. Each message must have a `role` (user/assistant) and `content` (string or array of content blocks) |
| `max_tokens` | integer | ✅ Yes | - | 1-64000 | Maximum number of tokens to generate. The model may stop before reaching this limit |
| `tools` | array | ✅ Yes | - | - | Array of tool objects. For web search, must include the web\_search tool configuration with type `web_search_20250305` |
| `temperature` | number | ❌ No | `1.0` | 0.0-1.0 | Controls randomness in output. Use lower values (closer to 0.0) for analytical tasks, higher values (closer to 1.0) for creative tasks. Note: Even at 0.0, results are not fully deterministic |
| `top_p` | number | ❌ No | - | 0.0-1.0 | Nucleus sampling threshold. Controls diversity by considering only tokens with cumulative probability up to top\_p. Recommended for advanced use only. Do not use with temperature |
| `top_k` | integer | ❌ No | - | >0 | Only sample from the top K options for each token. Removes low probability responses. Recommended for advanced use only |
| `stream` | boolean | ❌ No | `false` | - | Whether to stream the response incrementally using server-sent events |
| `stop_sequences` | array | ❌ No | - | Max 8191 sequences | Custom text sequences that will cause the model to stop generating. Each sequence must contain non-whitespace characters |
### Messages Array Structure
Each message object in the `messages` array should have the following structure:
| Field | Type | Required | Range | Description |
| --------- | ------------ | -------- | ----- | ------------------------------------------------------------------------------------------------------------------------------- |
| `role` | string | ✅ Yes | - | The role of the message. Can be: `user` or `assistant` |
| `content` | string/array | ✅ Yes | - | The content of the message. Can be a simple string for text-only messages, or an array of content blocks for multimodal content |
### Content Block Structure (when content is an array)
| Field | Type | Required | Range | Description |
| ------ | ------ | -------- | ----- | ---------------- |
| `type` | string | ✅ Yes | - | Must be `text` |
| `text` | string | ✅ Yes | - | The text content |
### Tools Array Structure
For web search functionality, the `tools` array should contain a web search tool object:
| Field | Type | Required | Range | Description |
| ----------------- | ------- | -------- | ----- | -------------------------------------------------------------------------------------- |
| `type` | string | ✅ Yes | - | The type of tool. Must be `web_search_20250305` for web search |
| `name` | string | ✅ Yes | - | The name of the tool. Use `web_search` |
| `max_uses` | integer | ❌ No | 1-10 | Maximum number of times the web search tool can be used in a single request |
| `allowed_domains` | array | ❌ No | - | Only include search results from these domains. Cannot be used with `blocked_domains` |
| `blocked_domains` | array | ❌ No | - | Never include search results from these domains. Cannot be used with `allowed_domains` |
| `user_location` | object | ❌ No | - | Localize search results based on user's location |
#### Max Uses
The `max_uses` parameter limits the number of searches performed. If Claude attempts more searches than allowed, the `web_search_tool_result` will be an error with the `max_uses_exceeded` error code.
#### Domain Filtering
When using domain filters:
* Domains should not include the HTTP/HTTPS scheme (use `example.com` instead of `https://example.com`)
* Subdomains are automatically included (`example.com` covers `docs.example.com`)
* Specific subdomains restrict results to only that subdomain (`docs.example.com` returns only results from that subdomain, not from `example.com` or `api.example.com`)
* Subpaths are supported (`example.com/blog`)
* You can use either `allowed_domains` or `blocked_domains`, but not both in the same request
* Request-level domain restrictions must be compatible with organization-level domain restrictions configured in the Console
#### User Location Structure
The `user_location` object allows you to localize search results based on a user's location:
| Field | Type | Required | Range | Description |
| ---------- | ------ | -------- | ----- | -------------------------------------------------- |
| `type` | string | ✅ Yes | - | The type of location. Must be `approximate` |
| `city` | string | ✅ Yes | - | The city name (e.g., `San Francisco`) |
| `region` | string | ✅ Yes | - | The region or state (e.g., `California`) |
| `country` | string | ✅ Yes | - | The country code (e.g., `US`) |
| `timezone` | string | ✅ Yes | - | The IANA timezone ID (e.g., `America/Los_Angeles`) |
