How this service works
Discover actively-promoted discounted products in a category above a minimum discount threshold. Returns deals ranked by discount depth with price, list price, and retailer.
Output
Returns a list of deal objects ranked by discount depth, each containing product details, current price, original list price, discount percentage, and retailer name, along with the resolved canonical category name.
Example use cases
Example prompt
“Find me the top 10 actively-promoted deals in electronics from Amazon in the US, with at least 20% off — ranked by biggest discount.”
Technical details
Endpoint
GEThttps://api.syntalic.com/v1/shopper/deal-finderWhen to prefer
Use this endpoint when you need a curated list of currently active promotional deals within a broad product category, especially when you want to filter by retailer, minimum discount depth, or country. Prefer this over Best Price when you want category-wide deal discovery rather than price comparison for a specific known product. Prefer this over Promo Intelligence when you need actual product listings rather than aggregate promo statistics.
Side effects
- Category not resolvable — if the provided category string is too vague or misspelled and cannot be mapped to a canonical category_id, the endpoint may return an empty deals array or an error
- No deals found — if no products in the category meet the minimum discount threshold, an empty deals array is returned
- Invalid retailer enum — if an unsupported retailer string is passed, a validation error is returned
- Limit exceeded — if limit exceeds 50, a validation error is returned
- Unsupported country — only 'us' and 'ca' are accepted; other values return a validation error
- Payment failure — if the x402 micropayment of $0.01 USDC is not processed, the request is rejected

|---|---|---|
| limit | integer | Max results to return (default 20, max 50) |
