A comprehensive PDF toolkit that handles pretty much everything you'd need to do with PDFs through a single API. Convert documents, HTML, or URLs to PDF, merge and split files, run OCR on scanned documents, add watermarks, extract pages, compress files, and even work with barcodes and form data. The API design is straightforward with base64-encoded content in JSON requests, though you'll be writing temporary files and piping through jq frequently. It's the kind of tool that replaces a dozen single-purpose PDF libraries, which is convenient until you hit an edge case and realize you're dependent on one service for your entire PDF workflow. Good documentation with working examples for each endpoint.
