Make, change, fill and read PDFs. Merge, split, reorder, rotate and delete pages (deleted content is removed from the file); stamp text, images, QR codes, watermarks and page numbers in any script; fill a PDF's form fields by name, or place values on any PDF, and save form templates to fill by id; protect with AES-256 and unlock; read text per page, markdown for LLMs, form fields and document facts; turn images into PDFs. Files go in by id, URL, base64 or as the body, and every result is a hosted file whose id feeds the next call. One key, JSON in and out, with an MCP server for agents. Operated by APIDirectory.
