Each backlink entry includes the source URL, destination URL, anchor text, link title, and page score, providing a thorough understanding of the link's origin and context. This detailed information helps users assess which external sites contribute most to their domain's authority and identify potential opportunities for link building or partnerships. The API also distinguishes between new and lost backlinks, enabling continuous tracking of changes in a domain's backlink ecosystem.
With data covering millions of referring domains and billions of individual backlinks, this API offers unmatched scope and reliability. The backlink summary section provides an at-a-glance overview of total backlinks, domain diversity, and authority score, while the backlink list offers useful details for deeper analysis.

To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used 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.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
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, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
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.
