AbuseIPDB bulk blacklist — the most-reported abusive IPs above a confidence threshold, the canonical fail2ban / firewall block-feed. Returns ipAddress, countryCode, abuseConfidenceScore, and lastReportedAt for each entry, plus the list's generatedAt timestamp. Tune confidenceMinimum (25-100, default 90), limit (1-10000, default 100), ipVersion (4 or 6), and onlyCountries / exceptCountries (comma-separated ISO-2). Live crowd-sourced threat feed for populating drop lists, WAF rules, and edge blocklists.
/api/security/ip-blacklistPAYMENT-SIGNATURE.The ip blacklist API is a pay-per-call security endpoint built for AI agents and autonomous software. AbuseIPDB bulk blacklist — the most-reported abusive IPs above a confidence threshold, the canonical fail2ban / firewall block-feed.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in ip blacklist data source for an agent tool-use loop, an MCP host, or a backend that needs security data on demand without onboarding to yet another vendor portal.
