Gs1 runs on your own machine — the client starts it, so there is no endpoint to ping. 38 installs a week from npm.
GS1 element strings, DataMatrix, eight keys, ITF-14 print specs and price-embedded in-store codes.
Today is the operative word: we check Gs1 every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
