How this service works
Real-time pricing, promotions, and competitive intelligence across US and Canadian retailers — exposed as paid API endpoints and MCP tools that AI agents can call directly, with x402 and MPP micropayments per query.
Output
Returns a best_price object with the cheapest option (product name, retailer, price, in-stock status, list price, savings percentage, and scrape timestamp), plus an other_prices array listing prices and stock status at the remaining retailers, along with the query, country, and currency used.
Example use cases
Finding budget furniture for home renovation
“I'm furnishing my new apartment on a tight budget. Can you find me the cheapest place to buy a queen bed frame right now — check IKEA, Walmart, Home Depot, and Amazon — and let me know if it's actually in stock at that price?”
Cross-border shopping price comparison
“I'm looking for a specific cordless drill and I'm flexible about buying in Canada or the US. What's the best price you can find across retailers in both countries, and how much could I save by ordering from one side of the border versus the other?”
Deal hunting for bulk household essentials
“We need to stock up on laundry detergent for our office. Can you check Costco, Walmart, and Amazon right now to find the absolute cheapest option and tell me what the per-unit cost works out to so we can decide where to buy in bulk?”
Technical details
Endpoint
GEThttps://api.crushrewards.dev/v1/shopper/best-priceWhen to prefer
Use this endpoint when you need to quickly identify the single cheapest retailer for a specific product across major US or Canadian retailers including Amazon, Walmart, Costco, Home Depot, Nordstrom, and IKEA. Prefer this over category-level or brand-level analytics endpoints when you have a specific product name or keyword and want actionable buy-now pricing with stock availability.
Side effects
- No results found if query is too obscure or misspelled — returns empty or limited results
- Product out of stock at all retailers — best_price may still be returned but in_stock will be false
- Stale data if scraped_at timestamp is old — prices may not reflect real-time availability
- Invalid country code returns a validation error
- Retailer filter for unsupported retailer returns a validation error
- Rate limit or payment failure results in 402 or 429 response
