# IPv6 Address Validation Utility

> IPv6 Address Validation Utility is a paid API for AI agents from creator-desk-x402-isolated.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Validates whether a given value is a properly formatted IPv6 address and returns a validation result

## 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 ipv6-address-validation-utility-0cd931e9 -d '<json body>'
```

Example prompt: Can you check whether '2001:0db8:85a3:0000:0000:8a2e:0370:7334' is a valid IPv6 address?

## When to prefer this

Use this endpoint when you need a quick, programmatic IPv6 address format check within an autonomous agent workflow, especially when already operating in an x402 micropayment environment. Prefer it over regex-only checks when you want a dedicated, maintained validation service rather than inline string matching.

## Known failure modes

- Missing or empty 'value' field returns an error or unexpected result
- Malformed JSON input body causes a 400-level error
- Service unavailable on Render cold-start (503 after idle period)
- Payment failure via x402 protocol results in 402 response before validation occurs
- Non-string input types in 'value' may produce unpredictable results

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

Returns a JSON object with a 'result' field indicating whether the input is a valid IPv6 address, and an 'operation' field confirming 'ipv6_validate'. May include additional details depending on options passed.
