How this service works
Search
Output
Returns a structured object containing product listings matching the query along with filter facets (category, rating, program eligibility, availability, price range) and location-specific data such as stock status, fulfillment node, and order quantity limits when a delivery_location is provided.
Example use cases
Find local Costco grocery availability
“Search Costco for 'almond milk' and filter results to my ZIP code 10001 in New York so I can see which ones are in stock and available for delivery to me.”
Compare Costco Canada product options
“Can you search Costco Canada for 'air purifier' in French (fr-CA) and show me what's available? I'm in Montreal with postal code H3A 1A1.”
Browse Costco electronics with pagination
“Search Costco for 'laptop' in the US and skip the first 20 results so I can see the next page of products — I'm near Seattle, ZIP 98101.”
Technical details
Endpoint
GEThttps://agents.openwebninja.com/realtime-costco-data/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, location-aware Costco product search results — especially when stock availability, fulfillment node, or order quantity limits matter for a specific US ZIP or Canadian postal code. Prefer this over static product databases when you need live Costco catalog data including current filter facets and availability status.
Side effects
- Missing required 'query' parameter returns a validation error
- Invalid country code (not US or CA) causes a bad request response
- Invalid language for the selected country (e.g. fr-CA with country=US) causes an error
- Invalid ZIP or postal code format for delivery_location may return unscoped or empty results
- Query returns zero results for niche or misspelled search terms
- Service may be rate-limited or return errors during high traffic periods
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| queryrequired | string | Search query. |
| start | number | Number of results to skip (offset). |
| country | string | The Costco country / domain to use. US or CA. |
| language | string | The language to use for the results. Defaults to the first / major language in the specified country - en-US for country=US and en-CA for country=CA. Allowed values: en-US for US / en-CA or fr-CA for CA. |
| delivery_location | string | Delivery location to scope results to, as a ZIP code for country=US (e.g. 98101) or a postal code for country=CA (e.g. M4V 2H7). Costco's catalog is fulfilled from location-specific distribution, grocery and pickup centers, so this affects which products are available, which node fulfills them (item_location_locationNumber), their stock status (item_location_availability) and the order quantity limits (item_location_fulfillment_restrictions_minQty / maxQty). Note that Costco list prices are national, so this does not change prices. When omitted, results are not scoped to any location. |
