The Oracle runs a dedicated probe service that periodically contacts public API endpoints operated by independent attestation authorities. For each authority, it records whether the endpoint responded, how quickly it responded, and whether the response matched the expected format.
These authorities include organizations like the Global Legal Entity Identifier Foundation (GLEIF), the Financial Industry Regulatory Authority (FINRA), the European Central Bank (ECB), and the Federal Risk and Authorization Management Program (FedRAMP), among others. All probed endpoints are publicly accessible APIs operated by these independent organizations — the Oracle does not require special access.
The probe runs every 5 minutes as a separate service from the Oracle's network monitoring. Commerce observation results never influence the Oracle's core network assessments (status, trend, risk, agreement, confidence, or data quality as reported on the homepage and through /organism).
