Technical details
Endpoint
GEThttps://dealpulse.theaslangroupllc.com/api/deals/stackWhen to prefer
Use this endpoint when a user wants to maximize total savings by combining multiple discount layers (portal cashback + credit card rewards + coupons + loyalty points) rather than finding just one type of deal. Prefer this over single-category endpoints (coupon-only or cashback-only) when the goal is holistic savings optimization for a specific purchase.
Side effects
- Store not supported — no cashback or coupon data available for that retailer
- Invalid or unresolvable store URL — returns 400 with a store not found error
- No stackable deals found — returns a result with zero savings opportunities
- Cashback portal data stale — rates may not reflect real-time portal offers
- Credit card rewards data unavailable for the specified card
