## 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 has-sendgrid-domain-verification-watch-c4e31e06
```

Example prompt: Keep an eye on whether acme.com has SendGrid domain verification set up — let me know if anything changes from the last time you checked.

## When to prefer this

Choose this endpoint when you need to continuously monitor whether a specific domain has SendGrid domain verification DNS records in place and want to be alerted to any configuration changes over time. It is ideal for automated workflows, compliance monitoring, or competitive intelligence where you need change detection rather than a simple one-time lookup. Prefer it over a plain DNS lookup when historical comparison and change tracking across 90-day windows is required.

## Known failure modes

- Domain not found or unresolvable — returns error or empty verification result
- No previous check stored (first call) — changed flag defaults to false or null with no comparison data
- DNS lookup timeout or upstream resolver failure — may return error or stale result
- Invalid or malformed domain input — returns validation error
- Rate limit or payment failure — returns 402 or quota error

## How this service works

Change watch for has sendgrid domain verification: 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 SendGrid domain verification status, a boolean indicating whether it changed since the last check, a list of fields that changed with before and after values, and a timestamp of when the result was last seen. Historical comparison data is retained for 90 days.
