I used base64 encoding of the image of the pdf page. The output was an object that has the markdown, and coordinates for the images:

[OCRPageObject(index=0, markdown='', images=[OCRImageObject(id='img-0.jpeg', top_left_x=140, top_left_y=65, bottom_right_x=2136, bottom_right_y=1635, image_base64=None)], dimensions=OCRPageDimensions(dpi=200, height=1778, width=2300))] model='mistral-ocr-2503-completion' usage_info=OCRUsageInfo(pages_processed=1, doc_size_bytes=634209)
