AbuseIPDB subnet (CIDR) check — which IPs inside a network block have been reported for abuse. Pass network as a CIDR (e.g. 118.25.0.0/24; AbuseIPDB supports up to /16 for IPv4, /112 for IPv6). Returns the block metadata (network/netmask/min-max addresses, possible hosts, address-space description) plus reportedAddress: each flagged IP with numReports, abuseConfidenceScore, mostRecentReport, and country. Optional maxAgeInDays (1-365, default 30) and limit. Use to vet a hosting range, score a customer's netblock, or sweep your own allocation.
/api/security/ip-blockPAYMENT-SIGNATURE.The ip block API is a pay-per-call security endpoint built for AI agents and autonomous software. AbuseIPDB subnet (CIDR) check — which IPs inside a network block have been reported for abuse.
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 block 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.
