How this service works
200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
Returns a JSON object containing the original input IP, its normalized form, IP version (4 or 6), address range classification (e.g. 'private', 'public', 'loopback'), and the ipv4_mapped field (null for native IPv4, populated for IPv4-mapped IPv6 addresses).
Example use cases
Classify incoming request IP
“I'm seeing traffic from 198.51.100.7 in my logs — can you tell me if that's a public or private IP and what version it is?”
Normalize and validate user-submitted IP
“A user submitted '::ffff:192.168.0.1' as their IP — can you normalize it and tell me what range it belongs to?”
Security audit of suspicious address
“We got a connection attempt from 10.0.0.254 — look it up and tell me if it's a private range address or something external I should worry about.”
Technical details
Endpoint
GEThttps://fastx402.tools/ip-info?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need lightweight, no-account IP address metadata — specifically range classification (private/public/reserved), version detection, and normalization — without requiring API key setup. Ideal for agents performing quick IP checks in security, logging, or network validation workflows at minimal cost ($0.001/call).
Side effects
- Missing or invalid 'ip' query parameter returns an error
- Malformed IP strings that aren't valid IPv4 or IPv6 may return an error or unexpected range
- Payment failure via x402 protocol results in 402 response and no data returned
