## 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 is-email-hosted-by-salesforce-email-change-watch-9b120145
```

Example prompt: Keep an eye on salesforce-email hosting for acmecorp.com and let me know if the result changes from last time — specifically whether it's still hosted by Salesforce Email and what fields flipped.

## When to prefer this

Choose this endpoint when you need to detect transitions in Salesforce Email hosting for a domain over time, not just a one-time lookup. It is ideal for scheduled polling workflows, sales-signal pipelines, or IT change-management alerts where knowing that something changed (and exactly what) matters as much as the current state. Prefer the non-watch variant if you only need a single point-in-time answer.

## Known failure modes

- Domain not provided or malformed — request fails with a validation error
- No previous result exists (first call for domain) — 'changed' field may be null or baseline; no diff available
- MX lookup failure via Cloudflare DoH — DNS resolution error returned
- Domain does not exist or has no MX records — check returns false with no hosting provider identified
- Stored result expired (older than 90 days) — treated as first call with no prior comparison baseline

## How this service works

Change watch for is email hosted by salesforce email: 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's email is hosted by Salesforce Email, a 'changed' true/false flag comparing against the last stored result (kept up to 90 days), a list of fields that changed with before/after values, and the timestamp of when it was last seen.
