Web Development

You know those tasks that aren't complex enough to justify a dependency but annoying enough to keep reimplementing?

• Validate an email address (syntax + MX records + disposable check)
• Decode a JWT without installing a library
• Look up DNS records
• Check SSL certificate expiry
• Generate a QR code
• Convert between base64 and text
• Explain a cron expression in plain English

Built a simple REST API that handles all of these. Returns JSON, works with curl, no auth needed for 50 req/day.

# Quick examples

curl http://5.78.129.127/api/cron/explain?expr=0+9+*+*+1-5

28 endpoints total. Docs at http://5.78.129.127/api/

It's not trying to compete with Postman or anything — it's more like a swiss army knife for when you need a quick answer and don't want to install anything.
