Hey Product Hunt I'm Raushan, founder of Corenexis. This one started as plumbing. We kept needing the same unglamorous things across our own products — turn a photo of a bill into text, generate a UPI QR, render an invoice as a PDF, check whether an email at signup was real. Each one meant a different vendor, a different dashboard, a different key, a different bill, and a different set of docs to read at 2am. So we built them once, properly, and put them behind a single key. Corenexis API Platform is 9+ production REST APIs: Markdown and HTML to PDF, OCR for images and scanned PDFs across 30+ languages, email validation with SMTP and DMARC checks, disposable email detection against a 146k+ domain database, image conversion across 25+ formats, an image CDN, and QR and barcode generation including UPI. Three decisions I'd defend: One key, one header. X-API-Key on every endpoint. No SDK to install and no OAuth dance to wire up just to convert a PDF. A free tier on every API, not a trial. You can build on free and stay there while a side project is small. New accounts also get $5 in credit, no card. Credit-based billing. You subscribe per API and pay for what you use, instead of buying one plan sized around the single API you use most. Everything returns predictable JSON with documented error codes, endpoints are versioned and backward compatible, and there are copy-paste snippets in seven languages. Free key: dash.corenexis.com One thing I'm curious about — which of these did you last go hunting for a vendor for? I want to know which one people hit first.
