Corenexis API Platform

Corenexis API Platform is a developer-first suite of nine production REST APIs, built so a single key and a single header get you to production quickly. The catalogue covers document work - Markdown to PDF and HTML to PDF with full modern CSS, plus OCR that turns images and scanned PDFs into clean text and markdown across 30+ languages. It covers media - image conversion across 25+ formats including AVIF, HEIC and JPEG XL, and a global image CDN. And it covers data quality - real-time email validation with SMTP, MX, SPF and DMARC checks, and disposable email detection backed by a 146k+ domain database. QR code and barcode generation rounds it out, including UPI payment QRs. Every API is versioned, TLS encrypted, documented with copy-paste snippets, and starts on a free tier.
