Get raw link graph counts for a domain, including inbound edges and unique linking domains.

GET/v1/domain-rank2 creditsAPI key

Returns the raw link graph statistics behind a domain's authority: how many inbound edges it has, how many distinct domains link to it, and the average size of those linking domains. Use it when you want the underlying counts rather than the 0 to 100 score from Domain Authority. Data comes from the domain link graph (see Response format).

Behavior and limits

Credits: 2 per call, charged before the lookup. Server errors are refunded.
Caching: results are cached for 30 days per crawl release. A cache hit is billed the same as a fresh lookup.
Empty results: a domain with no data returns 200 with all three values set to 0, never 404.
Rate limit: 60 requests per minute per key. See Rate limiting.

Errors

HTTP	Code	When
400	`invalid_domain`	`domain` is missing or not a valid domain.
401	`invalid_api_key`	Missing, invalid or revoked API key.
402	`insufficient_credits`	Balance is lower than the call cost.
402	`spend_cap_reached`	Your monthly spend cap is reached.
429	`rate_limited`	More than 60 requests in a minute.
503	`query_timeout`, `upstream_error`	Transient data store problem. Retry after the `Retry-After` header. Credits are refunded.
