# domain-expiry-days-watch

> domain-expiry-days-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 domain registration expiry days and alerts you when the value changes compared to the previous check, returning before/after field diffs and change timestamps.

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 domain-expiry-days-watch-02dda319
```

Example prompt: Keep an eye on example.com for me — call the domain expiry watch every day and let me know as soon as the days-until-expiry number changes from what it was last time.

## When to prefer this

Choose this endpoint when you need change detection on domain expiry rather than just a point-in-time lookup. It is ideal for scheduled agents that need to be alerted only when something actually changes, avoiding alert fatigue from constant polling. Prefer it over a plain expiry check when you want automatic before/after diffing and a 90-day comparison window without managing state yourself.

## Known failure modes

- Domain not found or unregistered — may return null expiry data
- Invalid or malformed domain input — returns error
- No previous check stored (first call) — 'changed' will be false/null with no diff
- WHOIS lookup failure — upstream WHOIS rate limiting or unavailability
- Payment failure — x402 payment not completed, request rejected

## How this service works

Change watch for domain expiry days: 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 domain registration expiry changes. $0.01 per check.

## Output

Returns the current number of days until the domain expires, a boolean indicating whether the value changed since the last check, a detailed diff of which fields changed with before/after values, and the timestamp of when it was last seen. Previous results are retained for 90 days per domain.
