# TLD Info Change Watch

> TLD Info Change 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 TLD (top-level domain) information for a given domain and returns whether it has changed since the last check, with before/after field diffs

## 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 tld-info-change-watch-abdf0e19
```

Example prompt: Keep an eye on the TLD info for example.com and let me know if anything changes — things like registry, status, or expiry — compared to the last time you checked.

## When to prefer this

Choose this endpoint when you need to detect changes in TLD-level domain registry information over time, rather than performing a one-off lookup. It is ideal for scheduled agent workflows where you want to be notified only when something actually changes, with structured before/after diffs rather than having to compare raw responses yourself. Prefer it over a plain TLD info lookup when you need change detection, audit trails, or alerting logic built in.

## Known failure modes

- Missing or invalid domain query parameter — returns error indicating required input
- Domain not found or unresolvable TLD — may return empty or error result
- No prior result stored (first call) — changed flag may be false or undefined with no diff
- Results older than 90 days purged — comparison baseline lost, treated as first call
- Network timeout fetching live TLD data — may return partial or error response

## How this service works

Change watch for tld info: 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 tld information changes. $0.01 per check.

## Output

Returns the current TLD information for the domain, a boolean 'changed' flag indicating whether anything differs from the previous call, a list of exactly which fields changed with their before and after values, and the timestamp of when the data was last seen. Previous results are stored for 90 days for comparison.
