How to use Domain Authority

A 0 to 100 authority score for a domain, with every input shown: its Common Crawl web graph harmonic centrality and PageRank positions and its Majestic Million rank and referring subnets. Only domains inside the top of the open rank lists are scored; an unranked domain is not proof of low authority. It is a link-graph score, not Moz or Semrush authority.

Send these fields in the JSON body of the request.

The data object of a successful response carries these fields. Every response also lists its sources, the credits_charged and whether it was a cache_hit.

Each field is described in the API reference.

10 credits per domain found in the rank data (an unranked domain is free).

You can try it without an account in the free tool. The free tools share a limit per visitor.

From code, send a POST request to https://YOUR_API_HOST/v1/domain-authority with your API key.

1curl -X POST https://YOUR_API_HOST/v1/domain-authority \
2  -H "Authorization: Bearer $LOOKVALID_API_KEY" \
3  -H "Content-Type: application/json" \
4  -d '{"domain":"wikipedia.org"}'

Full parameters and response fields are in the API reference. To run a list of values, use a bulk CSV job.

• Invalid input and errors are never charged.
• The API allows 200 requests per 10 seconds per key.
