- Send X-API-Key in request headers
- Rate limit
- 600 req/min
- Timeout
- 5000 ms
Send your API Key in the X-API-Key header from your backend.
Check both HTTP status and business fields before treating a call as successful.
Use retries and backoff together with rate limits in high-frequency scenarios.
Request Fields
Send requests from your server with the key in the X-API-Key header.

API Capabilities
The Product Barcode Query API allows developers to retrieve basic product information by inputting a standard product barcode (e.g., the common 13-digit EAN-13 code). The returned data typically includes product name, brand, reference price, and manufacturer. This API helps developers quickly build a product information database, reducing manual entry costs.
Request and Response
- Request Parameters: Only
barcode(product barcode) needs to be provided. Ensure the input barcode is a pure numeric string. - Return Results: The API will return a JSON object containing product information. Core fields include
name(product name),brand(brand),price(reference price, usually the suggested retail price), andmanufacturer(manufacturer). - Troubleshooting Failures: If no product is found, please check if the barcode was entered correctly, or if the product uses a non-standard barcode or an internal circulation code.
Use Cases
- Retail POS and Scanning: Quickly identify and display product information by scanning barcodes in POS systems or mobile applications.
