What does Onesimpleapi do?
Onesimpleapi is a collection of over 16 utility APIs bundled under one subscription. Instead of building and maintaining your own screenshot service, PDF generator, email validator, image processor, QR code generator, URL shortener, and more, you get them all with a single integration. The service handles scaling, uptime, and edge cases so you can focus on your product. It's designed for developers, no-code makers, e-commerce teams, and agencies who need reliable utility functions without the overhead.
Each API is a simple REST endpoint with clear documentation and a live playground to test calls. You can generate screenshots of any URL, convert pages to PDFs, validate email addresses, resize and optimize images, create QR codes, shorten URLs, check page status, extract SEO metadata, get real-time exchange rates, and even calculate purchasing-power-parity discounts. The service works with any programming language and integrates with automation tools like Zapier, Make, and n8n. Plans start with a free trial (100 requests) and scale up to 150,000 requests per month.
Onesimpleapi is best for developers who want to add common features to their apps without building them from scratch. SaaS builders can generate invoices as PDFs, verify emails at signup, and create shareable previews. E-commerce teams can auto-resize product images, generate QR codes for packaging, and offer location-based pricing. Marketing teams can clean email lists, track links, and analyze content readability. The service promises 99.9% uptime and human support, with a 14-day money-back guarantee.
