Each endpoint returns specific SEO metrics. The "Get Domain Authority" endpoint provides Domain Authority, PageRank, Global Rank, and Spam Score. The "Get Backlink Profile" endpoint returns total backlinks, unique referring domains, and top linking URLs. The "Get Referring Domains" endpoint lists external domains linking to the target, while the "Compare Domains" endpoint offers a side-by-side comparison of multiple domains' authority metrics.
Key fields vary by endpoint. For "Get Domain Authority," fields include domain, pageRank, rank, domainAuthority, and spamScore. The "Get Backlink Profile" includes totalBacklinks, referringDomainsCount, and topBacklinks. The "Get Referring Domains" features totalFound and referringDomains, while "Compare Domains" provides domains and a leaderboard with rank, domain, pageRank, domainAuthority, and spamScore.
Response data is structured in JSON format. Each endpoint returns an object containing relevant fields. For example, "Get Domain Authority" returns a single object with metrics, while "Get Backlink Profile" returns an object with total backlinks and an array of top linking URLs. This structure allows for easy parsing and integration into applications.
The "Get Domain Authority" endpoint provides authority scores and spam metrics. The "Get Backlink Profile" offers insights into backlinks and referring domains. The "Get Referring Domains" endpoint lists unique domains linking to the target, and the "Compare Domains" endpoint allows users to analyze multiple domains' authority metrics side by side, facilitating competitive analysis.
Data is sourced from reputable platforms: Domain Authority and Spam Score are derived from Moz, PageRank and Global Rank from Open PageRank, and backlinks and referring domains from Common Crawl. This combination ensures comprehensive and reliable SEO insights.
Users can customize requests by specifying the target domain in the endpoint parameters. For example, when using "Get Domain Authority," simply provide the desired domain as a parameter. For "Compare Domains," users can input 2 to 5 domains for comparison, tailoring the output to their specific analysis needs.
Typical use cases include SEO audits, competitor analysis, and client reporting. Developers can integrate the API into SEO tools, while agencies can automate research and generate insights for clients. Freelancers may use it for quick assessments of domain authority and backlink profiles.
Users can leverage the returned data to assess domain credibility, identify backlink opportunities, and compare competitors. For instance, the Domain Authority score helps gauge a site's SEO strength, while the backlink profile reveals potential link-building strategies. This data can inform SEO strategies and enhance digital marketing efforts.
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.
