# IP Address Info Lookup

> IP Address Info Lookup is a paid API for AI agents from agent-data-tools.revmesh2074.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Returns metadata about an IP address including version, public/private classification, integer representation, loopback/link-local flags, and reverse DNS.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ip-address-info-lookup-f3631e39
```

Example prompt: Can you look up the details for the IP address 203.0.113.42 — I want to know if it's public or private, what IP version it is, and what its reverse DNS resolves to?

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call IP address metadata without API keys — especially useful for agents enriching log data, validating network addresses, or checking public/private status of IPs across agentic workflows.

## Known failure modes

- Missing or invalid 'ip' query parameter returns an error
- Malformed IP string (e.g. letters) may return an error or unexpected classification
- Private/reserved IPs may have no reverse DNS, returning an empty or default reverseDns value
- Payment failure via x402 means the call is not charged and no result is returned

## How this service works

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.

## Output

A JSON object containing the queried IP address string, its IP version (4 or 6), boolean flags for public, private, loopback, and link-local classification, its integer representation, and its reverse DNS record.
