Could you build this?
Partial Packaging Typst into an API is doable, but achieving sub-10ms performance, PDF/A-3b compliance, and certified EU Factur-X / Schematron XML validation requires serious systems and compliance engineering.
What it would actually take: Requires writing a high-performance daemon in Rust embedding the Typst compiler in-memory to avoid process start overhead. It requires implementing specialized XML generators conforming strictly to UN/CEFACT CII, Schematron validation engines, and low-level PDF dictionary manipulation to embed metadata attachments adhering to ISO 19005-3 specs. Expertise in European electronic invoicing standards (EN 16931, XRechnung) and Rust systems programming is necessary.

Concerns raised: Appears to be just a wrapper around Typst compiler, Unclear value proposition over writing custom Typst templates, AI-generated landing page and repository presentation, Unjustified pricing
Feature requests: Clarify benefits over directly using Typst
