security.ip-reputation

Multi-source IP reputation with one combined authority score (0-100). Polls four independent reputation sources in parallel and blends them: AbuseIPDB (crowd-sourced abuse confidence), abuse.ch threat-lists (Feodo botnet C2 + ThreatFox + Spamhaus DROP + Tor exit nodes), blocklist.de (fail2ban attack-report network), and StopForumSpam. Returns combinedScore, a verdict (clean / low / suspicious / malicious), which sources flagged it, per-source opinions (score + weight + detail), and enrichment (ISP, usage type, country, ASN, Tor). An authoritative threat-list hit (botnet/malware/hijacked netblock) hard-floors the verdict at malicious. Per-source isolation: a down feed degrades that opinion only. The one-call answer for 'should I trust this IP?' instead of trusting a single feed.

Overview

The ip reputation API is a pay-per-call security endpoint built for AI agents and autonomous software. Multi-source IP reputation with one combined authority score (0-100).

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 reputation 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.

Code samples

cURLbash
# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/security/ip-reputation?ip=xxx'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/security/ip-reputation?ip=xxx' \
  -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-reputation?ip=xxx'

// 1. Add @2sio/mcp to your MCP host config (Claude Desktop example below).
//    EVM_PRIVATE_KEY funds x402 payments per call.

FAQ

Do I need an API key to use the ip reputation API?
No. security.ip-reputation is x402-native — there is no signup and no API key. Your client makes the call, receives a 402 with payment requirements, signs a USDC payment, and retries. Funds come from a wallet you control.
How much does the ip reputation API cost?
$0.0036 USDC per call, charged per request. There are no monthly fees, seats, or minimums — you pay only for the calls you make.
Can I try the ip reputation API for free first?
Yes. Add ?trial=1 (or the header X-2s-Trial: 1) to get a free real call per endpoint per hour, so you can verify the response shape before wiring payment.
Which networks and tokens are supported?
USDC on Base (via EIP-3009 transferWithAuthorization) or Solana (SPL transfer), using the open x402 payment protocol.
How do I call security.ip-reputation from an AI agent or MCP host?
Use @2sio/sdk (TypeScript), 2sio (Python), or the @2sio/mcp server for any MCP host — each handles the probe → sign → retry loop for you. See the code samples on this page.
