Welcome to the Q&A Forum

To get Domain Authority (DA) using an API:

Choose a Service: Use platforms like Moz, Ahrefs, or SEMrush, which provide domain metrics.
Sign Up: Create an account and subscribe to a plan that includes API access.
Get API Key: Obtain an API key or token for authentication.
Make Requests: Use the API to query DA for specific domains via tools like Postman or scripts.

Sign Up for Moz Pro: You need a Moz Pro account to access the API, which provides programmatic access to Moz's metrics, including Domain Authority (DA), Page Authority (PA), and other link metrics.

1. Moz API (Official Domain Authority Provider)
   Moz is the creator of the Domain Authority metric, and it provides an API to fetch DA data.

Steps:
Sign Up for Moz API Access:

Visit Moz's API page and create an account.
Choose a plan (free plans may have limited functionality).
Generate API Credentials:

After signing up, generate your API key (Access ID and Secret Key).
Use the API to Fetch Domain Authority:

The URL Metrics API endpoint provides domain metrics.
Send a request including your API credentials and the domain name.

@adrianTNT I understand your frustration with the documentation, as it can be challenging to navigate through multiple versions and unclear URLs. Based on my experience, Domain Authority is typically part of paid API plans, and some platforms might have shifted focus to metrics like Brand Authority. It would help if the documentation included clearer labeling and sample API calls.

@adrianTNT said in How to get Domain Authority using API ?:

I wanted to test the API and while looking on the documentation urls, I cannot find details on how to get Domain Authority.

is that not available to query ?
was it replaced by Brand Authority ?
is it only available for the paid API or for the free one too ?

I looked at many documentation pages but I find it very confusing and frustrating, there are many versions of the documentation and various URLs and not clearly labeled, I understand some are V1, V2, V3, etc, but I didn't find sample API calls for Domain Authority.
Thank you.

I understand your frustration with the documentation. It can be challenging to navigate through various versions. As far as I know, Domain Authority might not be directly accessible in the newer API versions and could be replaced by Brand Authority metrics. It's worth checking if it's exclusive to the paid API. For clarity, reaching out to their support team might help. Best of luck!

There were few sites offering this in the past, but as of now they seem to have some issues. Let me see if i can find a working website. Will update you asap

To get Domain Authority (DA) using an API, you can use services from providers like Moz, Ahrefs, or Semrush, which offer APIs that include domain authority and similar metrics. Here’s a step-by-step guide on how to get Domain Authority using the Moz API, one of the most popular tools for this metric:

1. Register for a Moz API Key
   Go to the Moz API page at Moz API.
   Sign up for an account and generate an Access ID and Secret Key. You’ll need these credentials to authenticate your API requests.
2. Make an API Request to Retrieve Domain Authority
   The Moz API’s Link Explorer endpoint can provide Domain Authority data.

You can get Domain Authority using APIs like Moz, SEMrush, or Ahrefs by integrating their API with your system.

SEMrush: They provide a different metric, “Authority Score,” which is available via API with a SEMrush subscription.
Free Domain Authority Checkers: Some free tools offer DA lookups, but they may not provide API access without premium plans.

Hi there @adrianTNT
Sorry for the confusion, we have new shiny methods to call DA being released shortly, until then you can use the current V2 API - https://moz.com/help/links-api/making-calls/url-metrics

We have more info on using the Moz API and limits here https://moz.com/help/links-api

"How can I find Domain Authority details through the API?"

Or, if you want a more detailed question:

"Is Domain Authority available to query through the API, or has Brand Authority replaced it? I checked multiple documentation versions (V1, V2, V3, etc.) but couldn't find a clear answer. Could you clarify if Domain Authority is only accessible via a paid API, and provide sample API calls for it if available?"

This should encourage a clear response on whether Domain Authority is supported, if Brand Authority is a replacement and details on the access level required.
