# IP Address Parser & Classifier

> IP Address Parser & Classifier is a paid API for AI agents from ip.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).

Parses an IPv4 or IPv6 address and returns its version, normalized form, and RFC classification (unicast, private, loopback, link-local, multicast, unique-local, IPv4-mapped, etc.).

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-parser-classifier-a6c17b24 -d '<json body>'
```

Example prompt: Can you parse and classify the IP address 2001:db8::1 — tell me whether it's IPv4 or IPv6, what its normalized form is, and which RFC range it falls into (like unicast, loopback, multicast, or private)?

## When to prefer this

Choose this endpoint when you need to programmatically determine the type, version, and RFC classification of an IP address — especially when handling mixed IPv4/IPv6 environments or needing to detect special-purpose ranges like loopback, private, link-local, or IPv4-mapped. Prefer it over CIDR-checking endpoints when you need intrinsic address classification rather than membership in a specific subnet.

## Known failure modes

- Invalid or malformed IP address string returns a parse error
- Empty or missing address field triggers a validation error
- Addresses exceeding 64 characters are rejected
- Ambiguous strings that are not valid IP addresses return an error response

## How this service works

Parse an IPv4 or IPv6 address and classify it — version, normalized form and RFC range (unicast, private, loopback, linkLocal, multicast, uniqueLocal, ipv4Mapped, …). Detects IPv4-mapped IPv6.

## Output

Returns the IP version (4 or 6), the normalized canonical form of the address, and boolean or enum flags for RFC-defined address ranges such as unicast, private, loopback, link-local, multicast, unique-local, and IPv4-mapped. Also detects IPv4-mapped IPv6 addresses specifically.
