## 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 spf-authorizes-hubspot-change-watch-73546829
```

Example prompt: Keep an eye on whether acmecorp.com's SPF record authorizes HubSpot — let me know as soon as that changes from the last time you checked.

## When to prefer this

Use this endpoint when you need to be alerted specifically to changes in whether a domain's SPF record authorizes HubSpot, rather than just performing a one-time lookup. Ideal for scheduled monitoring workflows where you want to detect when a company adds or removes HubSpot from their email-sending infrastructure over time.

## Known failure modes

- Domain not found or invalid — returns an error or empty result
- No previous check stored (first call) — 'changed' will be false or undefined as there's no baseline
- DNS lookup timeout — may return an error indicating the check could not be completed
- Domain has no SPF record — result reflects absence rather than explicit denial

## How this service works

Change watch for spf authorizes hubspot: 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 SPF-authorizes-HubSpot result (true/false), a 'changed' boolean, a list of fields that changed with before and after values, and the timestamp when the record was last seen. Results are compared against the previous check for the same domain, which is retained for 90 days.
