Each endpoint returns specific SEO-related data: the "Get Domain Authority" endpoint provides metrics like Domain Authority and Spam Score; "Get Backlink Profile" offers total backlinks and unique referring domains; "Get Referring Domains" lists external domains linking to the target; and "Compare Domains" delivers a side-by-side comparison of multiple domains' authority metrics.
Key fields include "domain," "domainAuthority," "spamScore," "totalBacklinks," and "referringDomainsCount" for the respective endpoints. For example, "Get Backlink Profile" includes "topBacklinks" with URLs and metadata, while "Compare Domains" features "leaderboard" with ranks and scores for each domain.
Response data is structured in JSON format, with each endpoint returning a specific object. For instance, "Get Backlink Profile" returns an object containing total backlinks and an array of "topBacklinks," while "Compare Domains" returns a leaderboard array detailing the rank and metrics of each domain.
Each endpoint provides distinct information: "Get Domain Authority" offers authority scores; "Get Backlink Profile" details backlinks and referring domains; "Get Referring Domains" lists unique domains linking to the target; and "Compare Domains" presents comparative metrics for multiple domains.
Data is sourced from reputable platforms: Domain Authority and Spam Score are from Moz, PageRank and Global Rank come from Open PageRank, and backlinks and referring domains are managed by Common Crawl, ensuring a comprehensive and reliable data set.
Users can customize requests by specifying the target domain in the endpoint parameters. For example, when using "Get Domain Authority," simply input the desired domain to retrieve its specific metrics. Each endpoint accepts a single domain or multiple domains for comparison.
Typical use cases include SEO audits, competitor analysis, and client reporting. Developers can integrate the API into tools for real-time backlink analysis, while agencies can automate research and generate insights for client presentations using the comparative data.
Users can leverage the returned data for strategic decision-making. For instance, the "Get Backlink Profile" can identify strong linking domains for outreach, while "Compare Domains" helps visualize competitive positioning, aiding in SEO strategy formulation and client pitches.
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.
