What differs for JSON API
For reports built from JSON sent to an API, the lowest paid starting price is $1 a month, from Api2Pdf. Published starting prices run from $1 to $250 a month, the top end from Formstack Documents.
These tools for reports most often write PDF (35), DOCX (15) and PPTX (9). 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.
