What problem does it solve?

Walmart flyer deal extraction turns hard-to-scrape flyer content into structured grocery deals you can plug into meal planning and shopping list generation.

Core Features & Use Cases

  • Flipp API extraction (no browser): Fetches the Walmart Canada flyer data directly from backflipp.wishabi.com, avoiding CAPTCHA/iframe scraping.
  • Deal normalization: Produces JSON deal records with category/product_type heuristics and computed regular_price when discounts exist.
  • Guardrails via drift detection: Runs pre-scrape and post-scrape checks to catch API breakage or partial/invalid responses before continuing.

Quick Start

Use this skill to parse the Walmart Canada weekly flyer deals for your area by providing the flyer URL context, then let it output a JSON array of extracted grocery deals.
