Official EU CBAM (Carbon Border Adjustment Mechanism) default embedded-emissions values, CN code coverage, and certificate/cost calculations for importers.
Each endpoint returns specific data related to the EU CBAM. The Health Check endpoint provides operational status and data version. The Get Covered Sectors endpoint lists sectors and CN code counts. The Calculate Embedded Emissions endpoint returns emissions calculations, required certificates, and cost estimates. The Lookup CN Code endpoint provides coverage, sector, and emissions values for specific CN codes.
Key fields vary by endpoint. For example, the Calculate Embedded Emissions endpoint includes `embedded_emissions_tco2e`, `certificates_required`, and `cost_estimate`. The Get Covered Sectors endpoint includes `name`, `label`, and `cn_code_count`. Each endpoint's response structure is tailored to its specific function.
Parameters vary by endpoint. The Calculate Embedded Emissions endpoint requires `cn_code` and `quantity_tonnes`, with an optional `origin_country`. The Lookup CN Code endpoint accepts `cn_code` and an optional `origin_country` parameter to retrieve specific data. Users should refer to the endpoint documentation for detailed parameter requirements.
Response data is organized in JSON format, with structured fields relevant to each endpoint. For instance, the Calculate Embedded Emissions response includes nested objects for `cost_estimate` and `default_embedded_emissions`. This structured format allows for easy parsing and integration into applications.
The data is sourced directly from the European Commission, ensuring it reflects the latest regulations and standards related to the CBAM. This official source enhances the reliability and accuracy of the data provided through the API.
Typical use cases include calculating embedded emissions for imports, determining required CBAM certificates, and assessing costs associated with carbon adjustments. Importers can use this data to comply with EU regulations and optimize their supply chain decisions.
Users can utilize the returned data by integrating it into their compliance systems to automate emissions calculations and reporting. For example, the embedded emissions data can inform sustainability strategies and help businesses meet regulatory requirements efficiently.
Data accuracy is maintained through regular updates from the European Commission and adherence to established regulations. The API reflects the latest regulatory changes, and users are encouraged to verify critical data with customs advisors for compliance purposes.
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.
Yes. If the API offers a free trial, you will see a "Free 7-Day Trial" option in its Pricing section. The trial lasts for 7 days and allows up to 50 API requests, enabling you to evaluate the API before subscribing to a paid plan.
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.
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.
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.
