What differs for JSON API

For labels built from JSON sent to an API, the lowest paid starting price is $7 a month after conversion to dollars, from PDF Generator API. Published starting prices run from $7 to $29 a month, the top end from CraftMyPDF.

These tools for labels most often write PDF (4). All 4 read JSON sent to an API without a Zapier, Make or n8n step in between. Your own code decides when to call the API, so a document can be built on any event. Prices were checked on 20 Oct 2026.
