NoPhishy vs URLScan.io

NoPhishy (listed on RapidAPI as Exerra Phishing Check) queries a maintained database of 299,000+ known phishing domains, refreshed roughly every two hours, to flag whether a submitted URL or domain is a known phishing attempt. A live GET through the real RapidAPI gateway host with an invalid x-rapidapi-key returned a 403 rejection rather than a network-level block, reconfirming API-key auth over HTTPS, and Access-Control-Allow-Origin echoed the request's Origin on that same call. Like other RapidAPI-distributed APIs it offers a free Basic plan alongside paid tiers for higher request volumes.

urlscan.io submits URLs to a real, sandboxed browser and publishes the resulting screenshot, DOM, requested domains, and detected technologies, plus a searchable archive of past scans, all as JSON. A live unauthenticated GET against its search endpoint succeeded immediately (returning IP-scoped X-Rate-Limit headers), and a follow-up OPTIONS preflight returned Access-Control-Allow-Origin: *, resolving cors to yes and confirming HTTPS; submitting new scans instead requires an API-Key header. Public scanning is free within per-minute/hour/day rate limits, with a paid urlscan Pro tier for vetted researchers needing deeper private search.
