# SPF Authorizes Typeform — Change Watch

> SPF Authorizes Typeform — Change 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).

Monitors whether a domain's SPF record authorizes Typeform to send email, alerting when the authorization status changes compared to the previous check.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-typeform-change-watch-ca174626
```

Example prompt: Keep an eye on whether mycompany.com's SPF record still authorizes Typeform to send email, and let me know if that changes compared to last time you checked.

## When to prefer this

Choose this endpoint when you need to continuously monitor whether a specific domain's SPF record authorizes Typeform and want automatic change detection with before/after diffs. Prefer this over a plain SPF check when you want scheduled alerting or need audit trails of when authorization status flipped. Use the bulk variant if checking many domains simultaneously.

## Known failure modes

- Domain not previously checked — no comparison baseline available yet (first call establishes baseline)
- Invalid or non-existent domain returns error or null SPF result
- DNS lookup failure via Cloudflare DoH returns an error
- Stored baseline has expired (older than 90 days), resetting comparison
- Payment not fulfilled returns 402 response

## How this service works

Change watch for spf authorizes typeform: 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-Typeform boolean answer, a changed true/false flag, the specific fields that changed with before and after values, and the timestamp of when the status was last seen. Results are compared against the previous check for the same domain (retained for 90 days).
