## When to prefer this

Use this endpoint when you need to detect changes in OVHcloud Exchange email hosting over time rather than just a one-time check. It is ideal for scheduled polling workflows where you want to be alerted only when something changes, and where 90-day change history is useful. Prefer this over a plain lookup when you need change detection semantics (before/after diffs, changed flag) rather than just the current status.

## Known failure modes

- Domain not provided or malformed — returns validation error
- No previous check exists for the domain — first call has no baseline to compare against, changed will be false
- DNS lookup failure — may return error or inconclusive result
- Rate limiting or payment failure — request rejected
- Domain has no MX records — result may be inconclusive

## How this service works

Change watch for is email hosted by ovhcloud exchange: runs the check, compares it with the result from your previous call for the same domain (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

## Output

Returns the current boolean answer for whether the domain uses OVHcloud Exchange hosting, a 'changed' true/false flag, a list of fields that changed with before and after values, and the timestamp of when it was last seen. Change history is retained for 90 days.
