How this service works
ShieldAPI - x402 security preflight before agents connect to IP infrastructure
Output
Returns a JSON object with the queried IP, an array of blacklist check results (name, listed status, and optional DNSBL response), a risk_level string (e.g. 'medium'), a numeric risk_score, a boolean is_tor_exit flag, and the reverse DNS hostname.
Example use cases
Example prompt
“Can you check if the IP address 203.0.113.45 is blacklisted or has any security risks — I want to know its risk score, whether it's a TOR exit node, and which spam blacklists it appears on?”
Technical details
Endpoint
GEThttps://shield.vainplex.dev/api/cdp/check-ipWhen to prefer
Use this endpoint when you need to quickly assess whether a specific IPv4 address poses a security threat, is listed on major spam/abuse blacklists (Spamhaus ZEN, SpamCop, SORBS, Barracuda), or is operating as a TOR exit node. Prefer this focused IP check over the full security scan endpoint when you only need IP-specific intelligence and want to minimize cost and latency.
Side effects
- Invalid or malformed IPv4 address returns an error response
- Private or reserved IP ranges may not return meaningful blacklist data
- Payment failure or insufficient USDC balance prevents the call from completing
- Rate limiting may occur under high request volume
- Blacklist data may be slightly stale depending on upstream provider refresh cycles
