Pass a file URL in your messages using the `file_url` content type:

```json
{
  "model": "sonar-pro",
  "messages": [
    {
      "role": "user",
      "content": [
        {"type": "text", "text": "Summarize this document and fact-check the key claims."},
        {"type": "file_url", "file_url": {"url": "https://example.com/report.pdf"}}
      ]
    }
  ]
}
