IP address facts

$0.003 per call · failed calls are never charged · no account or API key needed

Classify an IPv4 or IPv6 address without any lookup: version, whether it is private, loopback, link-local, carrier-grade NAT or public, and its integer and reverse-DNS forms (IPv4). Use to triage IPs in logs or allowlists.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/ip/info?ip=10.1.2.3"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/ip/info?ip=10.1.2.3&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum, Monad, World Chain or Tempo) and retries.

Example result

{
  "ip": "10.1.2.3",
  "version": 4,
  "private": true,
  "loopback": false,
  "linkLocal": false,
