How this service works
Change watch for spf authorizes yahoo: 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 Yahoo is authorized by the domain's SPF record, a 'changed' true/false flag, a list of fields that changed with before/after values, and the timestamp of when the result was last observed. Previous result is retained for 90 days.
Example use cases
Email deliverability drift alert
“Watch acmecorp.com and tell me if its SPF record starts or stops authorizing Yahoo — compare against what you saw last time and flag any changes.”
Post-migration SPF verification
“We just migrated our email setup for brandnew.io — can you check whether Yahoo is now authorized in the SPF record and compare it to our previous configuration?”
Ongoing compliance monitoring
“Set up a recurring check on techfirm.com so I get alerted whenever the SPF authorization for Yahoo flips from what was last recorded.”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/watch/email/spf-authorizes/yahoo?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need ongoing, scheduled monitoring of whether Yahoo is authorized in a domain's SPF record and want to be alerted only when the answer changes. Prefer this over a one-shot SPF check when you want change detection with before/after diffing and a 90-day history window. Ideal for automated deliverability pipelines, compliance checks, and post-migration verification workflows.
Side effects
- Domain not found or unresolvable — returns error or null result
- No previous check stored (first call) — 'changed' field may be null or false with no before/after diff
- SPF record temporarily unavailable due to DNS propagation — may return stale or inconclusive result
- Rate limiting or payment failure — request rejected at x402 payment layer
