      summary: Create a scan
      description: Scan text, TXT, Markdown, HTML, PDF, DOCX, static public HTTPS webpages, or public remote MCP server metadata. API keys require scan:write. Raw file uploads may be up to 10 MB. Anonymous, Free, and Personal extracted content is limited to 100,000 bytes; Pro extracted content is limited to 1,000,000 bytes. Free and Personal allow at most 25,000 input tokens. Every input type costs max(1, ceil(input_tokens / 1000)) Scan Units. Token rate limits apply to every input type. Query parameters are not supported.
