PDF.co API integration with managed OAuth. Convert, merge, split, edit PDFs and extract data. Use this skill when users want to convert PDFs to/from other formats, merge or split PDFs, add watermarks or text, extract text/tables, or parse invoices. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Calls run through the `maton` CLI with OAuth login; default to read and list calls, and confirm every write or new connection with the user.
CLI-first rewrite: the maton CLI with OAuth login is the documented path, every example is a maton command, SDK examples added, and the raw HTTP fallback feeds the key on stdin instead of reading it from the environment
