## 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-sendinblue-change-watch-b2d9c6cc
```

Example prompt: Keep watching whether example.com's SPF record authorizes Sendinblue and tell me if anything changes since the last time you checked.

## When to prefer this

Use this endpoint when you need to detect changes in SPF authorization for Sendinblue over time, rather than just querying the current state. Ideal for scheduled polling workflows where you want to be alerted only when something changes, avoiding noise from repeated identical results. Prefer over a one-shot SPF check when you need historical comparison and diff output.

## Known failure modes

- Domain not previously checked — no baseline to compare against (changed will be false or absent on first call)
- DNS lookup failure for the domain's SPF record
- Invalid or missing domain query parameter
- Baseline result expired after 90 days — treated as first check

## How this service works

Change watch for spf authorizes sendinblue: 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-Sendinblue answer (true/false), a 'changed' boolean indicating whether the result differs from the previous check (stored up to 90 days), the specific fields that changed with their before and after values, and the timestamp of when the status was last seen.
