OpenAPI Specification

openapi: 3.2.0
info:
  title: FFraud Compatibility API
  version: 1.0.0
  summary: Free, open IP and email fraud intelligence.
  description: 'Check any IP or email for fraud, VPN, proxy, Tor, datacenter, and abuse history. Free for everyone, no usage caps. The public endpoints need no API key; a free key adds batch lookups, usage stats, and the community reporting API. The database behind this API is published daily as MIT-licensed open data at https://github.com/FFraud-com .


    Drop-in compatibility endpoints let you migrate off AbuseIPDB, IPQualityScore, or ipinfo by changing one URL.'
