Verification Methodology
Explore how FreeLearn's automated engine verifies promotional coupons, stamps UTC validation times, and handles sudden quota expirations.
1. Official Source Aggregation
Our automated daemon continuously monitors legitimate instructor promotional distribution channels, official learning communities, and verified newsletters to identify candidate coupon codes.
2. Programmatic Checkout & UTC Timestamping
Before any listing is published, our validation server queries platform pricing endpoints to confirm 100% price reduction ($0.00 checkout). Upon verification, an immutable UTC timestamp is stamped onto the record.
Ensuring 100% off rather than standard promotional sales (e.g. $9.99 or $14.99 tiers).
Verifying whether the instructor's 1,000-seat allocation has been exhausted.
3. Sub-Hourly Re-checks & Community Alerts
Because popular courses can exhaust their 1,000-seat quota within hours, our verification daemon operates continuous sub-hourly audit cycles. The moment a coupon lapses, it is marked as EXPIRED and delisted from the active feed.
Community Reporting Integration:
When a reader clicks 'Report Expired Offer', the coupon is instantly escalated to VERIFY_PENDING for immediate automated confirmation.
