Is this serial flagged?
A public list of Mac serials that have been flagged as compromised. Serial lookup tells you what model a serial is; this list answers a different question: has this one been flagged as a reason to walk away? Macfax checks every report it issues against it and won’t certify a flagged serial.

Every Macfax report checks this list.
When a seller runs Macfax, we read the Mac's serial in the first second of the diagnostic and compare it against the registry. If the serial appears here, we refuse to issue a report. No charge, no exception. Buyers checking a report URL also see the registry status next to the report ID.
Free API.
eBay, Reddit, Swappa, FB Marketplace and others get free programmatic access. Daily CSV and BloomFilter available for offline checks at scan-time.

}A clean registry check is the floor. A report is proof.
The registry tells you a serial isn't flagged. A verified Macfax report tells you the Mac in front of you is real, healthy, and exactly what the listing claims.
