PDFGen AI

The service offers a REST API that creates PDF documents from supplied HTML or from templates generated by an AI model. Users can POST a request containing either raw HTML with placeholder variables or a prompt in plain English; the AI then produces a professional HTML template and identifies the required data fields. After providing a JSON object with the corresponding data, the API returns a URL to the rendered PDF, typically within a few seconds.

It includes a small collection of pre‑built templates for common document types such as invoices, receipts, reports, certificates, and letters. The platform handles data mapping automatically, linking JSON values to template variables without additional configuration. Authentication is performed with API keys, and built‑in rate limiting and usage tracking are provided by default.

The architecture is serverless, allowing the endpoint to scale with demand while maintaining low latency. The service is positioned as an experimental utility for developers who need to generate pixel‑perfect PDFs programmatically without managing a PDF rendering stack.
