What differs for JSON API
For certificates built from JSON sent to an API, the lowest paid starting price is $5 a month after conversion to dollars, from PDFMonkey. Published starting prices run from $5 to $49 a month, the top end from Bannerbear.
These tools for certificates most often write PDF (15), DOCX (2) and Google Docs (1). Among them, 4 need Zapier, Make or n8n to read JSON sent to an API, so they sit after the tools with a direct connection. 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.
