## 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-mailchimp-mandrill-watch-9a91433c
```

Example prompt: Keep an eye on acme.com and let me know if it starts or stops using Mailchimp or Mandrill for email — tell me what changed and when you last saw a different result.

## When to prefer this

Use this endpoint when you need to be alerted to changes in Mailchimp/Mandrill email hosting for a domain over time, rather than just a one-time point-in-time check. Ideal for scheduled polling workflows, competitive intelligence pipelines, or compliance monitoring where the delta (what changed) matters more than just the current state. Choose the non-watch sibling endpoint for a simple one-off check without change tracking.

## Known failure modes

- Domain not previously checked — no prior result to compare against, changed may default to true or null
- DNS resolution failure via Cloudflare DoH — may return error or indeterminate result
- Invalid or non-existent domain — MX lookup fails with error
- Rate limiting or payment failure — $0.02 USDC charge not processed, request rejected
- Prior result expired (older than 90 days) — comparison baseline lost, treated as first check

## How this service works

Change watch for is email hosted by mailchimp mandrill: 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 (is email hosted by Mailchimp/Mandrill), a 'changed' true/false flag compared to the previous call for the same domain (retained 90 days), a list of fields that changed with before/after values, and the timestamp of when it was last seen.
