Support for numerous formats: Compatible with a wide range of barcode types, including UPC, EAN, Code 128, and more, in addition to all standard QR code formats. Easy integration: Designed to seamlessly integrate with mobile apps and enterprise systems to enhance data capture and analytics.

The API predominantly utilizes the POST method, allowing users to upload images containing QR codes or barcodes. It processes these images to extract and return the encoded information in a structured format.

Yes, the API comes with usage limits that vary according to the subscription plan you select. Detailed information regarding these limits can be found on our pricing page or within your user dashboard.

Here are some common errors you may run into: 400 Bad Request: Typically indicates an issue with the input data, such as an unreadable or unsupported image format. 401 Unauthorized: Occurs if there is an issue with your API key, such as it being invalid or absent.

Each endpoint returns structured data that includes the decoded code, its type, and detailed field information. The response contains fields such as "code," "codeType," "allFields," and "codeArea," providing comprehensive details about the scanned QR code or barcode.

The key fields in the response data include "code" (the scanned value), "codeType" (the format of the code), "allFields" (an array of field details), and "codeArea" (coordinates of the code in the image), which help users understand the scanned content and its context.

The response data is organized in a JSON format, with a top-level structure containing "statusCode," "statusMessage," "hasError," and a "data" array. Each item in the "data" array represents a scanned code with its associated details, making it easy to parse and utilize.

Each endpoint provides information about the scanned QR code or barcode, including the decoded value, type of code, and additional fields such as field names and values. This allows users to extract relevant data for various applications, like inventory tracking or marketing.

The endpoints accept image data in three formats: Base64, image URL, or image file. Additionally, images must not exceed 8 MB in size and should be between 50 and 5000 pixels in dimensions to ensure successful processing.

Users can utilize the returned data by accessing the "code" for the scanned information, using "codeType" to determine the format, and leveraging "allFields" for detailed attributes. This structured data can be integrated into applications for tracking, analytics, or user engagement.

The API guarantees 100% accuracy in decoding QR codes and barcodes. It employs advanced image processing techniques to ensure reliable results, and users can verify the integrity of the data through the structured response format.

Typical use cases include product tracking in retail, managing inventory, analyzing consumer behavior in advertising, and enhancing user experiences in mobile applications. The API's versatility supports various industries and applications.

General FAQs

To obtain your API key, first sign in to your account and navigate to the API you want to use. From the API's Pricing section, choose a plan and complete the subscription process. Once subscribed, return to the API page and you will see your API Access Key displayed at the top of the documentation page. You can use this key to authenticate your requests.

You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.

The free trial lasts for 7 days and allows you to make up to 50 API requests.

No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.

Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.

Prices are listed in USD (United States Dollar), EUR (Euro), CAD (Canadian Dollar), AUD (Australian Dollar), and GBP (British Pound). We accept all major debit and credit cards. Our payment system uses the latest security technology and is powered by Stripe, one of the world's most reliable payment companies. If you have any trouble paying by card, just contact us at [email protected]

Additionally, if you already have an active subscription in any of these currencies (USD, EUR, CAD, AUD, GBP), that currency will remain for subsequent subscriptions. You can change the currency at any time as long as you don't have any active subscriptions.
The local currency shown on the pricing page is based on the country of your IP address and is provided for reference only. The actual prices are in USD (United States Dollar). When you make a payment, the charge will appear on your card statement in USD, even if you see the equivalent amount in your local currency on our website. This means you cannot pay directly with your local currency.
Occasionally, a bank may decline the charge due to its fraud protection settings. We suggest reaching out to your bank initially to check if they are blocking our charges. Also, you can access the Billing Portal and change the card associated to make the payment. If these does not work and you need further assistance, please contact our team at [email protected]
Prices are determined by a recurring monthly or yearly subscription, depending on the chosen plan.
API calls are deducted from your plan based on successful requests. Each plan comes with a specific number of calls that you can make per month. Only successful calls, indicated by a Status 200 response, will be counted against your total. This ensures that failed or incomplete requests do not impact your monthly quota.
Zyla API Hub works on a recurring monthly subscription system. Your billing cycle will start the day you purchase one of the paid plans, and it will renew the same day of the next month. So be aware to cancel your subscription beforehand if you want to avoid future charges.
To upgrade your current subscription plan, simply go to the pricing page of the API and select the plan you want to upgrade to. The upgrade will be instant, allowing you to immediately enjoy the features of the new plan. Please note that any remaining calls from your previous plan will not be carried over to the new plan, so be aware of this when upgrading. You will be charged the full amount of the new plan.
To check how many API calls you have left for the current month, refer to the 'X-Zyla-API-Calls-Monthly-Remaining' field in the response header. For example, if your plan allows 1,000 requests per month and you've used 100, this field in the response header will indicate 900 remaining calls.

You can monitor your API usage through the response headers included with every request:

x-zyla-api-calls-monthly-used: Shows the total number of API requests you have used during the current billing period.
x-zyla-api-calls-monthly-remaining: Shows the number of API requests you have remaining for the current billing period.

The 'X-Zyla-RateLimit-Reset' header shows the number of seconds until your rate limit resets. This tells you when your request count will start fresh. For example, if it displays 3,600, it means 3,600 seconds are left until the limit resets.

Yes, you can cancel your subscription at any time. Simply go to the Pricing section of the API you're subscribed to and click the "Unsubscribe" button.

Please note that upgrades, downgrades, and cancellations take effect immediately. Once your subscription is canceled, access to the service will end immediately, regardless of any remaining API calls in your quota.

After 7 days, you will be charged the full amount for the plan you were subscribed to during the trial. Therefore, it's important to cancel before the trial period ends. Refund requests for forgetting to cancel on time are not accepted.
When you subscribe to an API free trial, you can make up to 50 API calls. If you wish to make additional API calls beyond this limit, the API will prompt you to perform an "Start Your Paid Plan." You can find the "Start Your Paid Plan" button in your profile under Subscription -> Choose the API you are subscribed to -> Pricing tab.
