Prompt
How do I find a REST API for product catalog data?
Latest observation
To find a REST API for product catalog data, you usually want to search in a few specific places depending on whether you need a public API, a vendor API, or a dataset/API for testing.
1) Clarify what kind of catalog data you need
Product catalog APIs can mean:
- Retail/e-commerce products: title, price, description, images, SKU, availability
- Marketplace catalogs: Amazon-like product listings
- Industry catalogs: electronics, books, groceries, etc.
- Demo/sample catalog data for development
2) Search targeted API directories
Good places to look:
- RapidAPI — lots of product/retail APIs
- Public APIs directories — search for “products”, “ecommerce”, “catalog”
- GitHub — search for “product catalog API”, “REST API products”
- Postman Public API Network — sometimes vendor collections are published there
Useful search terms:

3) Check major commerce platforms
If you want catalog data from a store or platform, many have REST APIs:
- Shopify Admin API / Storefront API
- WooCommerce REST API
- BigCommerce API
- Magento/Adobe Commerce API
- Salesforce Commerce Cloud APIs
These are best if you need access to a specific store’s catalog.
4) Look for product data providers
Some services offer product databases or enrichment APIs:
- Barcode/product lookup APIs
- Retail data APIs
- Manufacturer catalogs
- Price comparison APIs
Search with the domain you need, like:
barcode product lookup APIUPC product APIretail catalog data API
5) If you just need test data
You can use sample/demo APIs such as:
- DummyJSON
- Fake Store API
- Platzi Fake Store
- JSONPlaceholder (not product-specific, but useful for testing)
These provide simple REST endpoints with product-like data.
6) Evaluate the API before using it
Check:
- Does it have the fields you need?
- Is pricing data current?
- Rate limits
- Authentication requirements
- Terms of use
- Coverage by region/category
- Response format and filtering options
7) Example of what to ask for
If contacting a provider, ask:
“Do you provide a REST API for product catalog data with fields like name, SKU, price, description, images, inventory, and category? Is there documentation and a sandbox?”
If you want, I can also:
- help you find specific APIs for your use case,
- give you a shortlist of public product catalog APIs, or
- show you how to call one with cURL / Python / JavaScript.
