# SPF Authorizes Eventbrite – Change Watch

> SPF Authorizes Eventbrite – 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 2026-10-24).

Checks whether a domain's SPF record authorizes Eventbrite as a sender, compares the result to the previous check (retained 90 days), and returns what changed and when.

## 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-eventbrite-change-watch-7602373a
```

Example prompt: Keep an eye on whether the SPF record for mycompany.com still authorizes Eventbrite as a sender — let me know if anything has changed since the last check.

## When to prefer this

Use this endpoint when you need change-detection semantics — not just a point-in-time SPF lookup, but a diff against the previous result. Ideal for scheduled monitoring workflows where you want to be alerted only when the Eventbrite SPF authorization status actually changes. Prefer this over a plain SPF check when you care about drift, compliance continuity, or automated alerting on transitions.

## Known failure modes

- Domain not previously queried — no historical baseline available, so 'changed' cannot be determined on first call
- DNS lookup failure for the domain's SPF record — may return an error or indeterminate result
- Domain does not exist or has no SPF record — returns result indicating no authorization
- Payment failure via x402 protocol — call not executed
- Rate limiting or service unavailability — transient errors

## How this service works

Change watch for spf authorizes eventbrite: 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 boolean answer for whether the domain's SPF record authorizes Eventbrite, a 'changed' true/false flag, the specific fields that changed with before and after values, and the timestamp of when the state was last seen. Historical state is retained for 90 days for comparison.
