How this service works
Web extraction, domain lookups and document tools for AI agents. Pay per call in USDC via x402 on Base or Algorand.
Output
Returns the network owner (organization/ISP name), the IP address range or CIDR block the IP belongs to, the country associated with the IP, and the reverse DNS (PTR) record for the given IP address.
Example use cases
Identify suspicious login origin
“Someone logged into our app from 185.220.101.5 — can you look up who owns that IP, what country it's from, and what the reverse DNS resolves to?”
Investigate email sender's IP
“I got an email that claims to be from a bank but the sending server IP is 91.108.4.1 — find out who owns that IP and which country it's registered in.”
Enrich server access logs
“We're seeing traffic from 203.0.113.77 in our logs — look up the network owner, IP range, and reverse DNS so I can figure out if it's a bot or legit user.”
Technical details
Endpoint
GEThttps://agentpay.agentpay-apis.workers.dev/lookup/v1/ip?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single call to get all basic IP intelligence — owner, range, country, and rDNS — without having to separately query WHOIS, RDAP, and DNS PTR records. It is ideal for log enrichment, security investigations, and bot/fraud detection pipelines where speed and simplicity matter more than exhaustive ASN-level data.
Side effects
- Invalid or malformed IP address returns an error or empty response
- Private/reserved IP addresses (e.g. 192.168.x.x, 10.x.x.x) may return no meaningful owner data
- IP not found in WHOIS/routing databases returns null or minimal fields
- IPv6 addresses may have incomplete reverse DNS entries
- Payment failure or x402 auth issue blocks the request entirely
