## 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-braze-change-watch-166963ca
```

Example prompt: Keep an eye on whether acmecorp.com's SPF record still authorizes Braze to send email, and let me know if anything changes from last time you checked.

## When to prefer this

Use this endpoint when you need to detect changes in Braze SPF authorization over time rather than just a one-time lookup. It is ideal for scheduled polling workflows where you want to be alerted only when something changes, rather than re-processing the same static result. Prefer over a raw SPF check when change detection and before/after diffing are needed.

## Known failure modes

- Domain not previously checked — no prior result to compare against (first call acts as baseline)
- DNS lookup failure or timeout via Cloudflare DoH
- Invalid or malformed domain input
- 90-day history window exceeded — prior result no longer available for comparison
- Payment failure for $0.02 USDC charge via x402

## How this service works

Change watch for spf authorizes braze: 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-Braze boolean answer, a changed flag (true/false), the specific fields that changed with before and after values, and the timestamp of when the previous result was last seen. History is retained for 90 days.
