# Dynamic Document API

> Generate PDFs and images from HTML templates and JSON data through a REST API. EU-hosted by default, with versioned templates, signed webhooks and transparent credit pricing.

Dynamic Document API renders PDFs and images from HTML/Jinja templates and JSON data through a REST API (base URL https://api-eu.dynamicdocumentapi.com/v1). Authentication uses Bearer API keys; test keys render watermarked documents for free. Workspaces are hosted in the EU by default. Every documentation page is available as Markdown by appending `/index.md` to its URL or by requesting the page with `Accept: text/markdown`.
