InvoicePDF API generates PDFs without headless browser overhead

Developer Rahul built InvoicePDF, a lightweight API that converts JSON invoice data into PDFs using pure Python (fpdf2) instead of a headless Chromium browser. The service handles money as integer minor units to avoid floating-point errors, supports multiple currencies, and offers a free tier of 100 invoices per month. The open-source project is available on GitHub under an MIT license.
