This page is designed to help you find out whether NormAPI is good and if it is the right choice for you.
NormAPI generates XRechnung (UBL and CII) and ZUGFeRD invoices from JSON and validates XML and PDF invoices against the official KoSIT rule set, as a REST API and as a free browser validator without sign-up. Generated invoices are validated before they are returned, every response names the rule-set version, and every business-rule finding carries a plain-language explanation of cause and fix, in English or German. Processing runs in the EU without storing invoice contents. Free: validation, plus 25 generated invoices a month with an account; paid plans from €49 a month.

API-first developer approach
NormAPI is built for developers, so its services can be integrated into applications through REST-style endpoints instead of manual workflows. This usually means faster integration and easier automation. I could not verify the details of the current product, so check the live site for the exact feature set.
Reduces in-house development effort
Using a hosted API lets teams avoid building and maintaining this functionality themselves. That saves engineering time and ongoing maintenance, especially for small teams and startups.
Scalable, usage-based model
Hosted API services like this typically let you start small and scale with demand, so you don't have to manage infrastructure. Confirm the actual pricing tiers and rate limits on the official pricing page.
Language-agnostic integration
Because it is exposed over HTTP, it can be called from almost any language or platform, such as Python, JavaScript, Ruby, or PHP. This makes it flexible across different tech stacks.
Quick start for prototyping
A hosted API usually requires only an account and an API key, so teams can test and prototype quickly before committing to a larger integration.
