How this service works
ShieldAPI - x402 security preflight before agents connect to IP infrastructure
Output
Returns the queried IP with an array of blocklist results (including Spamhaus ZEN, SpamCop, SORBS, Barracuda with listed status and DNS response), an overall risk_level (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 203.0.113.42 is blacklisted or flagged as malicious — I want to know its risk score and whether it's a TOR exit node before I allow it through.”
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, has been flagged for spam or abuse, or is operating as a TOR exit node. Ideal for pre-authorization checks on incoming connections, validating user signup IPs, or enriching security logs with reputation data.
Side effects
- Invalid or non-IPv4 address format returns an error
- Private or reserved IP ranges may return incomplete results
- Blocklist services may be temporarily unavailable causing partial results
- Payment failure (402) if USDC balance is insufficient
- Rate limiting if too many requests are made in a short window
