Costco product data API: search and category listings with per-warehouse shelf price and stock, full item detail for up to 20 items, online vs in-warehouse prices at up to 10 warehouses with promotion dates, warehouse stock status, gas prices, the member coupon book, deal feeds, a clearance finder and reviews. 13 endpoints, mostly 1 credit each.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Costco Product Data API - Warehouse Prices, Stock, Gas, Coupons Search Costco, read items in full, compare the online price with the shelf price at specific warehouses, check warehouse stock, and pull gas prices, the member coupon book, deal feeds and clearance markdowns.

How to install
mdr add scavio-ai/skills/costco-product-data@sha256:50cb0cd3a784ff3aThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
