StopBot is a real-time bot detection API suite: block malicious traffic by IP/ASN/hostname/VPN reputation, verify emails and phone numbers, and run bot-aware smart URLs — all through one API key, with a dashboard for logs, blacklist/whitelist, and stats.

Hi Product Hunt 👋 I've been running StopBot — a real-time bot detection API — and decided to share it here. It plugs into your app with one API call: send IP + user-agent + URL, get back whether the visitor is a bot and why (IP reputation, hostname blacklist, ASN/hosting detection, VPN/Tor, country, device, threat feeds — 16 detection categories in total). Beyond blocking, the suite includes Smart URLs (shortlinks with bot detection baked in), IP Lookup, Email Validation (MX/SPF/DMARC/disposable check), and Phone Number Identify — same API key, one dashboard. Built from years on the defensive/pentesting side — I wanted something I'd actually trust in front of my own infra. Happy to answer anything about the detection logic or architecture.

Dropped a few suspicious IPs into the API and the ASN reputation check flagged stuff I wouldn't have caught manually. The bot-aware smart URLs are a clever touch for tracking real engagement.

Finally tried StopBot and the ASN and hostname filtering saved me a ton of time setting up firewall rules. The dashboard is clean and the API responses are refreshingly fast.
