API Documentation

Welcome to the Barcode Spider API

The quickest and easiest way to get started with Barcode Spider API is with the documentation below. The Barcode Spider API documentation describes how to use our RESTful API service. All API responses are returned in JSON format. If you have additional questions, please email support.


Every user account is assigned one unique API token upon account creation. Your API token is used to authenticate you with our API, and can be provided either as an request header or alternatively as a token URL parameter. Authenticate your account by including your API token in all requests.

# With request header $ curl -X GET -H "token: YOUR_TOKEN" https://api.barcodespider.com/v1/lookup $ curl -X GET -H "token: YOUR_TOKEN" https://api.barcodespider.com/v1/search # With token query parameter $ curl -X GET https://api.barcodespider.com/v1/lookup?token=YOUR_TOKEN $ curl -X GET https://api.barcodespider.com/v1/search?token=YOUR_TOKEN

Code Examples

Below are a few basic sample for the Lookup request to help you get started. The code examples demonstrate how to make an API call and print output in several popular programming languages.

$ curl -X GET -H 'token: YOUR_TOKEN' 'https://api.barcodespider.com/v1/lookup?upc=UPC_NUMBER'
$user_token = "ENTER YOUR API TOKEN HERE"; $endpoint = "https://api.barcodespider.com/v1/lookup"; $upc = "UPC_NUMBER"; $curl = curl_init(); curl_setopt_array($curl, array( CURLOPT_URL => $endpoint ."?upc=".$upc, CURLOPT_RETURNTRANSFER => true, CURLOPT_ENCODING => "", CURLOPT_MAXREDIRS => 10, CURLOPT_TIMEOUT => 30, CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1, CURLOPT_CUSTOMREQUEST => "GET", CURLOPT_POSTFIELDS => "", CURLOPT_HTTPHEADER => "token: YOUR_TOKEN", )); $response = curl_exec($curl); $err = curl_error($curl); curl_close($curl); if ($err) { echo "cURL Error #:" . $err; } else { echo $response; }
import requests url = "https://api.barcodespider.com/v1/lookup" querystring = {"upc":"UPC_NUMBER"} headers = { 'token': "ENTER YOUR API TOKEN HERE", 'Host': "api.barcodespider.com", 'Accept-Encoding': "gzip, deflate", 'Connection': "keep-alive", 'cache-control': "no-cache" } response = requests.request("GET", url, headers=headers, params=querystring) print(response.text)

HTTP Response Headers

Description of HTTP Response Headers returned from API. This information can be used to gauge your total number of allotted requests, the number of requests remaining for the day, and the time at which the daily limit will be reset. Any request that exceed the daily threshold will be throttled with an HTTP 429 response.

HTTP Header Type Description
X-RateLimit-Limit integer An integer specifying the number of requests available per day. This number is definied by your subscription plan.
X-RateLimit-Remaining integer An integer specifying the number of remaining requests per day.
X-RateLimit-Reset timestamp A timestamp specifying the time in which the daily rate limit is reset.
