## When to prefer this

Use this endpoint when you need a live, multi-retailer price comparison for a specific named product and want to find the absolute cheapest current price with a direct purchase link. Prefer this over a price history endpoint when the user wants to buy now rather than track trends, and over a coupon code endpoint when the user wants the baseline cheapest retailer rather than a discount on a specific store.

## Known failure modes

- Retailer data temporarily unavailable leads to incomplete comparison
- Ambiguous product query returns results for wrong item
- Price data may be slightly stale between crawl intervals
