Commerce intelligence for consumer electronics
Electronics is the category where price moves fastest and shoppers compare hardest. The same SKU sits at five sellers under five identifiers, discounting is seasonal and steep, and a model refresh silently strands last year's listing.

One SKU, five identifiers
An ASIN, a Best Buy SKU, a Walmart item id, a Target TCIN and a manufacturer part number all describe one pair of headphones. Resolution collapses them to a single canonical product with a checksum-verified GTIN, so a price comparison is a join rather than a guess.

Discount depth that survives scrutiny
Electronics list prices are frequently fiction. A percentile against the product's own history at that seller tells you whether $198 is genuinely the floor or merely the number printed next to a struck-through $398.

Model transitions
When a generation turns over, the old listing does not disappear — it drifts. match.degraded fires when a mapping's confidence falls, which is the difference between noticing a transition and quietly comparing an XM4 against an XM5 for a quarter.
Endpoints that do this
Where it lands in the API.
Price context
Is this actually a good price? Percentile against the product's own history at that seller, time-weighted, with low, median and high.
Compare
One product across every seller that carries it, ranked by landed cost, with the spread. Server-side work is worth more than four raw reads the caller has to join.
Events
Six event types, signed on delivery and replayable by cursor. Every consumer eventually needs to backfill a gap.
Questions
Common questions.
How current is electronics pricing?
Cadence is earned per listing: a product that moves on most reads is polled at its floor, one that has not moved since March drifts toward its ceiling. Median age is exposed per seller in the seller directory rather than promised in a marketing claim.
Can it tell a refurbished offer from a new one?
Yes. Condition and offer type ride on every offer, alongside seller identity, so a marketplace refurb never silently undercuts your new-unit comparison.
