Available Tools

serpex_search

Search the web using Serpex multi-engine API. Optionally fetches full page content (markdown) for the top results inline with the search — best-effort, so check each result for content vs content_error.

Parameters:

• q (required): Search query string (max 500 characters)

• include_content (optional, boolean): Also fetch full page content (markdown) for the top results. Best-effort — roughly 79% of result URLs return content; blocked or robots-disallowed pages return content_error instead. Default: false.

• content_results (optional, 5 | 10): Number of top results to fetch content for, when include_content is true. Must be exactly 5 or 10. Default: 5.

Example:

{
  "q": "artificial intelligence trends 2025",
  "include_content": true,
  "content_results": 5
}

Response (JSON, as tool output text) includes content_requested / content_delivered counts and, per result, content on success or content_error on failure — both keys are omitted when content wasn't requested.
