## 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-lever-change-watch-b8cc8550
```

Example prompt: Keep an eye on whether lever.co is still authorized in the SPF record for acme.com — let me know as soon as that changes, including what fields switched and what the before and after values were.

## When to prefer this

Use this endpoint when you need to be alerted to changes in whether a domain's SPF record authorizes Lever specifically, rather than just checking the current state. Ideal for scheduling periodic monitoring, audit trails, or compliance workflows where detecting the transition (authorized → unauthorized or vice versa) matters more than the current snapshot value alone.

## Known failure modes

- Domain not previously checked — no baseline for comparison, changed field may be null or false by default
- Invalid or non-existent domain — DNS lookup fails, returns error
- SPF record temporarily unavailable via Cloudflare DoH — transient DNS error
- Baseline expired after 90 days — previous result no longer available for comparison
- Rate limits or payment failure — call rejected with payment-required error

## How this service works

Change watch for spf authorizes lever: 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 authorization result for Lever (true/false), a 'changed' boolean comparing to the previous call (stored up to 90 days), a list of fields that changed with before and after values, and the timestamp of when the record was last seen.
