The Retail vertical at apis.io/industries/retail/ tracks 90 providers and 116 APIs across eight sub-sectors — mass merchants and supercenters, convenience stores, wholesale and warehouse clubs, department stores, specialty retail, and more.
Like financial services, it has no exemplar-band provider. Unlike financial services, its ceiling is even lower.
The bands
| Band | Providers | APIs |
|---|---|---|
| Developing | Advance Auto Parts 58.7, Wayfair 58.3, Albertsons 57.7, Urban Outfitters 57.1, BJ’s 54.4, Walgreens 53.1, Target 52.7, Walmart 52.4 | 2–25 |
| Thin | IKEA 39.0, Lowe’s 38.4, Skechers 38.3, Home Depot 33.7 | 1–6 |
The highest-scoring retailer on the network is Advance Auto Parts, an auto-parts chain, at 58.7. Walmart — the largest retailer on earth — publishes 25 APIs and scores 52.4. Home Depot publishes one and scores 33.7.
What’s shifted
Three patterns in the current data:
-
Specialty beats scale. Advance Auto Parts (58.7) and Urban Outfitters (57.1) outscore Target (52.7) and Walmart (52.4). Auto parts is a fitment problem — year, make, model, part number — that genuinely requires a queryable API, and the specialty retailers built one because the catalog was unusable without it.
-
Grocery is quietly ahead. Albertsons at 57.7 with 4 APIs. Grocery e-commerce forced integration with delivery platforms, and that pressure produced a described surface faster than general merchandise did.
-
The home-improvement floor is remarkable. Lowe’s at 38.4 with 3 APIs and Home Depot at 33.7 with 1. Two companies with enormous SKU counts, complex regional inventory, and a contractor customer base that would obviously consume an API — publishing almost nothing.
Retail versus commerce platforms
The instructive comparison is not within this vertical. It is against the platforms that sell to it.
Shopify, profiled today, publishes 213 APIs and scores 68.7. VTEX publishes 44. Commerce Layer and BigCommerce both carry substantially higher composites than any retailer in this list.
That is the same inversion visible in financial services, where Fiserv scores below the banks it serves — except here it runs the other way. The commerce platforms score above their retail customers, because for them the API is the product. For a retailer, the API is a cost center attached to a store.

Takeaway
90 of the world’s largest retailers publish 116 APIs between them, the ceiling is an auto-parts chain at 58.7, and Home Depot ships one API. Retail buys its API surface from platforms rather than building it — which works until the thing you need to expose is your own inventory.
