What differs for JSON API

For statements built from JSON sent to an API, the lowest paid starting price is $15 a month, from DocRaptor. Published starting prices run from $15 to $49 a month, the top end from Docmosis.

These tools for statements most often write PDF (6), DOCX (5) and XLSX (4). All 6 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.
