# SPF Authorizes Mailchimp Watch

> SPF Authorizes Mailchimp Watch is a paid API for AI agents from email.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-20).

Runs an SPF-authorizes-Mailchimp check for a domain, compares the result against the previous check (retained 90 days), and returns whether the authorization status changed along with before/after field values.

## 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-mailchimp-watch-94c5fc13
```

Example prompt: Keep an eye on whether mailchimp.com's SPF record still authorizes Mailchimp to send email — let me know if anything changes compared to the last time you checked.

## When to prefer this

Use this endpoint when you need to detect changes in a domain's SPF-based Mailchimp authorization over time rather than just checking the current status. It is ideal for scheduled polling workflows, deliverability compliance monitoring, or alerting pipelines where you want to know when something changes, not just what it currently is. Prefer this over a one-shot SPF check when you need historical comparison and delta reporting.

## Known failure modes

- Domain not found or invalid DNS response — returns an error or empty SPF result
- No previous check stored (first call for domain) — 'changed' cannot be determined, baseline is established
- DNS lookup timeout via Cloudflare DoH — check fails to return a result
- SPF record absent from domain — check returns no SPF authorization found
- Stale baseline (>90 days since last check) — previous result has expired and comparison is unavailable

## How this service works

Change watch for spf authorizes mailchimp: 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-Mailchimp result for the domain, a boolean 'changed' flag 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.
