security.ip-blacklist

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.

Code samples

cURLbash

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/security/ip-blacklist?confidenceMinimum=90&limit=100&ipVersion=1&onlyCountries=example&exceptCountries=example'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/security/ip-blacklist?confidenceMinimum=90&limit=100&ipVersion=1&onlyCountries=example&exceptCountries=example' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):
#   EVM_PRIVATE_KEY=0x... node --env-file=.env.local \
#     --experimental-strip-types scripts/x402-pay.ts \
#     'https://2s.io/api/security/ip-blacklist?confidenceMinimum=90&limit=100&ipVersion=1&onlyCountries=example&exceptCountries=example'
