## 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 contact-email-finder-change-watch-e6c59e71
```

Example prompt: Keep an eye on acmecorp.com for me — let me know whenever their public contact emails (like info@ or support@) change compared to what you last found, and show me exactly what was added or removed.

## When to prefer this

Choose this endpoint when you need to detect changes in a company's publicly listed contact emails over time rather than just retrieving them once. It is the right choice for scheduled monitoring workflows, sales intelligence pipelines that need to track when companies update their contact info, or compliance use cases where you must detect email address removals. Prefer the sibling contact-email-finder endpoint for a one-shot lookup without change detection.

## Known failure modes

- Domain is unreachable or returns no homepage content — returns empty email list with no diff
- First-ever call for a domain has no previous result to compare against — changed flag may be null or false with no diff
- Domain blocks automated scraping — may return empty or partial results
- 90-day retention window exceeded — previous result unavailable, diff cannot be computed
- Invalid or malformed domain input — request rejected with validation error

## How this service works

Change watch for contact email finder: 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 find public contact email addresses on a company's homepage changes. $0.01 per check.

## Output

Returns the current list of public contact email addresses found on the domain's homepage, a boolean 'changed' flag indicating whether results differ from the previous call, a field-level diff showing exactly which emails were added or removed (with before/after values), and a timestamp of when the data was last seen. Previous results are retained for 90 days for comparison.
