Available Tools

1. processlocalfile

Process a file from the configured OCR_DIR directory.

{
    "name": "process_local_file",
    "arguments": {
        "filename": "document.pdf"
    }
}

2. processurlfile

• For URLs: {url_filename}_{timestamp}.json or url_document_{timestamp}.json if no filename is found in the URL

The timestamp format is YYYYMMDD_HHMMSS.
