Mozilla http scanner vs PhishStats

The HTTP Observatory grades a website's security headers -- CSP, HSTS, cookie flags, and more -- against Mozilla's recommended baseline, the same engine behind the long-running Mozilla Observatory scanner. The original mozilla/http-observatory Python API was shut down on 2024-10-31 when the tool moved to MDN; automated callers now POST to a v2 scan endpoint that returns a grade, score, and pass/fail counts, with a details link back to the full MDN report. It's fully public and keyless, rate-limited to one fresh scan per host per minute (cached results are returned for repeat calls within that window), and built for CI-pipeline use.

PhishStats crowdsources and republishes a running feed of phishing URLs, screenshots, and detection metadata, giving anyone a free real-time phishing blocklist to query or download. The REST API — now served from api.phishstats.info after moving off its old port-based endpoint — supports complex filter queries against the phishing database and returns JSON records ready to stream into an existing security stack. Anonymous lookups are capped at 50 requests/day per IP; a free registered key raises that to 150/day, with paid tiers for higher volume.
