  1. """AbuseIPDB collector — SCAFFOLD, key-ready (like zefix.py).
  3. Free-tier API requires an API key (401 without; probe recorded 2026-09-24).
  4. Get a free key at https://www.abuseipdb.com/account/api after signup, then
  5. export LEASH_ABUSEIPDB_KEY=<key>
  6. and set abuseipdb.enabled=true in config/sources.json.
  8. Endpoint used: GET /api/v2/check?ipAddress=<ip>&maxAgeInDays=90
  9. Rate limits: free tier 1,000 checks/day — cached per IP, resume-safe.
  10. License: AbuseIPDB terms — free tier is for non-commercial use with
  11. attribution; responses should not be resold (see LICENSE_NOTES.md).
