What Factlint checks today
The European core is validated and sealed; the Peppol CIUS is not yet — its artefacts carry no published licence. See rulesets/peppol-2026-08.
EN 16931 is validated and sealed, but the national rules are not applied. The API response states this explicitly rather than letting you assume a national conformity that was never checked.
Do you build invoicing software?
You are the one carrying this deadline for your customers. Factlint fits upstream of your chain: one call validates, fixes what can be fixed without risk, and returns the exact list of what is missing. Above all, every verdict is rendered against a pinned, time-stamped rule set — so you can replay it years later, and test today against rules that are not yet in force.
