Product API

Overview

Go-UPC's API makes it easy to programmatically access information on products from all over the world. This documentation provides the details you should need to navigate our product database.

Authentication

We use an API key to verify requests. You should have received an API key when you signed up. If you've lost your API key or need a new one, please just send us an email.

Go-UPC provides two methods for including your API key when making a request. For simplicity and testing we allow you to include your key as a URL parameter; however we recommend the alternative method for production implementations, which involves passing the key via an Authorization header.

Examples

Method One

The API key must be included in the URL as the key query parameter.

curl "https://go-upc.com/api/v1/code/781138811156?key=<api_key>"

Method Two

The API key must be part of the of the HTTP header as a Bearer token.

curl --header "Authorization: Bearer <api_key>" https://go-upc.com/api/v1/code/781138811156

Limits

The number of lookups you're able to perform via the API varies depending on your plan, as do offered data formats and support options. See the table here for specifics.

Developer Startup Enterprise
Lookups Per Month 5,000 45,000 450,000
Available Formats JSON JSON, CSV JSON, CSV, XML

In addition to monthly limits, you're permitted a maximum of 2 requests per second. If you need a higher rate-limit, please contact us.
