# IPv6 Support Check Watch

> IPv6 Support Check Watch is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Monitors a domain's IPv6 readiness over time and returns a change report comparing current results to the previous check, including which fields changed and when.

## Facts

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 ipv6-support-check-watch-281a5651
```

Example prompt: Keep an eye on whether example.com has IPv6 support — run the check now and tell me if anything changed since the last time you looked, including exactly which fields are different and what they were before.

## When to prefer this

Choose this endpoint when you need to detect changes in IPv6 readiness for a domain over time rather than just a one-time status check. It is ideal for scheduled monitoring workflows, compliance tracking, or alerting pipelines where you need to know not just the current state but precisely what changed and when. Prefer it over a plain IPv6 check when field-level diffs and historical comparison (up to 90 days) are required.

## Known failure modes

- Domain not found or unresolvable — returns error or empty IPv6 result
- No prior check stored (first call) — 'changed' may default to false or null with no diff
- Payment not received — request rejected with 402 Payment Required
- Malformed domain input — returns validation error
- Upstream DNS/network timeout — check may fail or return partial data

## How this service works

Change watch for ipv6 support check: runs the check and compares it with the result from your previous call for the same domain (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when ipv6 readiness check for a domain changes. $0.01 per check.

## Output

Returns the current IPv6 support check result for the domain, a boolean 'changed' flag indicating whether the result differs from the previous call, a field-level diff showing exactly which fields changed along with before and after values, and a timestamp of when the result was last seen. Previous results are retained for 90 days.
