LaserYield

LaserYield maintains an independent, append-only archive of prices and product information published on company storefronts, reading and recording data on a daily basis. The service tracks list prices, reference prices, availability, and catalogue changes for specific retailers such as Apple UK, with the archive itself not editable once written.

The archive begins in August 2026 and has recorded zero days on Apple UK so far. It is designed to preserve historical pricing and listing data that retailers do not retain themselves, including information that gets removed or overwritten on the original storefront pages.

The collector reads the same shelves in the same order at six every morning to capture data. This routine ensures consistent observation of storefronts like Apple UK without relying on external APIs or automated scrapers that might fail.

Every observation is appended and never edited, with corrections arriving as new records rather than replacements. This method ensures the archive remains an immutable historical record of what was published.

The auditor publishes the proof by hashing each day's records and posting the hash so any later change to the archive is detectable. This transparency allows users to verify the integrity of the stored data.

The archive records the 'was' price and how long it was ever real, along with out-of-stock status model by model. It also captures pricing page structure and tiers that vanish unannounced.

The strongest signal is a removal, and the service records what was published in public and when. Nothing else archives those changes as effectively as this longitudinal approach.

The website states it is not investment advice and not an accusation about anyone. It simply observes that prices change overnight and the old number goes with them.

The archive is append-only and written once, never edited. This design choice ensures that every historical price point remains accessible and unaltered.

The service tracks catalogue changes weekly, including new listings and quiet removals. It also monitors the day a model first appears on the storefront.

The archive includes reference prices and the duration they were active, providing context for price fluctuations. It also tracks availability changes model by model.

The service monitors pricing page structure and tiers that vanish unannounced, capturing the full lifecycle of product offerings. It also records the specific timing of these changes.
