# Web fetch on abliteration.ai

> Server-side web fetch on abliteration.ai — let the model pull and read a specific URL via the Anthropic Messages API.

Web fetch lets the model pull a specific URL and read its contents server-side. Available on the **Anthropic messages API only**.

## Usage

```python theme={"system"}
client.messages.create(
    model="abliterated-model",
    max_tokens=4096,
    tools=[{
        "type": "web_fetch_2025_03_05",
        "name": "web_fetch",
        "max_uses": 3,
    }],
    messages=[{"role": "user", "content": "Summarize https://example.com/post"}],
)
```

## Response blocks

Fetched pages return as `web_fetch_tool_result` blocks:

```json theme={"system"}
"content": [
  {"type": "server_tool_use", "id": "srvtoolu_...", "name": "web_fetch", "input": {"url": "https://example.com/post"}},
  {"type": "web_fetch_tool_result", "tool_use_id": "srvtoolu_...", "content": {
    "type": "web_fetch_result",
    "url": "https://example.com/post",
    "content": [{"type": "text", "text": "..."}]
  }},
  {"type": "text", "text": "The post argues..."}
]
```

## Not available on OpenAI

Web fetch is not implemented on `/v1/chat/completions` or `/v1/responses`. For those surfaces, use [web search](/capabilities/web-search) and let the model pick a URL to cite.

## Domain allow/block

Same as web search — projects can restrict reachable domains via Policy Gateway. See [onboarding](/policy-gateway/onboarding).
