PolyDoc
PolyDoc converts HTML markup, live URLs, or Liquid-templated content into archival-grade PDFs (including PDF/A and PDF/UA variants), screenshots in PNG/JPEG/WebP, and EN 16931-compliant Factur-X/ZUGFeRD e-invoices. Results can come back synchronously, via webhook, or straight to cloud storage, and a no-card-required sandbox mode lets you test calls before spending production credits.
