FreeDailyPro
FreeDailyPro builds everyday document, text, media and calculator tools for developers and AI agents. On ApyHub the APIs cover PDF (merge, split, rotate, compress, fill forms, page numbers), PowerPoint, text and developer utilities, QR codes and barcodes, CSV, publishing metadata (ISBN, ONIX, spine width), loan, tax and retirement calculators, images, audio and video. Each endpoint takes your input and returns the finished result in one request.
Nothing you send is stored: files are processed in memory and discarded. Developers call the APIs from their code, and AI agents reach 220 of the same tools through MCP at api.freedailypro.com/mcp. The full platform has 300+ browser tools at freedailypro.com.
