Request Body

application/json

TypeScript Definitions

Use the request body type in TypeScript.

targets*array<>

Domains, subdomains, or pages to find common referring domains for (1-20). Order is preserved as the 1-based index in the response.

Items1 <= items <= 20

exclude_targets?array<>

Domains, subdomains, or pages to exclude (up to 10). Domains linking to these are dropped.

Itemsitems <= 10

intersection_mode?string

all (default) returns domains linking to any target; partial returns only domains linking to every target.

Value in"all" | "partial"

backlinks_status_type?SeoBacklinksStatusType

Which backlinks to count: live (found on the last check, default), all, or lost.

Value in"live" | "all" | "lost"

include_subdomains?boolean

Include backlinks pointing to the target's subdomains. Defaults to true.

include_indirect_links?boolean

Include indirect links (via redirects or canonicals) to the target. Defaults to true.

exclude_internal_backlinks?boolean

Exclude internal backlinks from the target's own subdomains. Defaults to true.

internal_list_limit?integer

Maximum number of entries kept in each referring_links_* breakdown map. Defaults to 10.

Range1 <= value <= 1000

rank_scale?SeoBacklinksRankScale

Scale for rank values: one_thousand (0-1000, default) or one_hundred (0-100).

Value in"one_hundred" | "one_thousand"

filters?||

Filter the intersecting domains. Prefix each metric field with the 1-based target index, e.g. 1.rank, 2.referring_domains. Provide a single condition {"field","op","value"} or an {"and":[…]} / {"or":[…]} group of conditions (nest groups for mixed logic), up to 8 conditions. Operators: =, <>, <, <=, >, >=, in, not_in, like, not_like, ilike, not_ilike, match, not_match (use an array value with in / not_in). Filterable fields: rank (backlink rank, 0-1000); backlinks (number of backlinks); backlinks_spam_score (average spam score, 0-100); referring_domains (referring domains count); referring_main_domains (referring root domains count); referring_pages (referring pages count); referring_ips (referring IPs count); referring_subnets (referring subnets count); broken_backlinks (backlinks to broken pages); broken_pages (broken pages still receiving backlinks); first_seen (ISO date the first backlink was found); lost_date (ISO date the last backlink was lost). Example: {"and":[{"field":"1.rank","op":">","value":300},{"field":"2.rank","op":">","value":300}]}

backlinks_filters?||

Filter the underlying individual backlinks before the aggregate metrics are computed. Provide a single condition {"field","op","value"} or an {"and":[…]} / {"or":[…]} group of conditions (nest groups for mixed logic), up to 8 conditions. Operators: =, <>, <, <=, >, >=, in, not_in, like, not_like, ilike, not_ilike, match, not_match (use an array value with in / not_in). Filterable fields: dofollow (boolean, link is dofollow); is_new (boolean, appeared since the last check); is_lost (boolean, lost since the last check); is_broken (boolean, points to a broken page); rank (referring page rank, 0-1000); page_from_rank (referring page rank, 0-1000); domain_from_rank (referring domain rank, 0-1000); backlink_spam_score (spam score of the referring page, 0-100); item_type (anchor, image, link, redirect, or canonical); anchor (anchor text); tld_from (top-level domain of the referring page); semantic_location (link location, e.g. article, footer); first_seen (ISO date the backlink was first seen); last_seen (ISO date the backlink was last seen). Example: {"and":[{"field":"dofollow","op":"=","value":true},{"field":"backlink_spam_score","op":"<","value":10}]}

order_by?array<>

Sort the intersecting domains. Prefix each field with the 1-based target index, e.g. 1.rank. Each rule is {"field","dir"} with dir asc or desc; up to 3 rules, applied in order. Sortable fields: rank, backlinks, backlinks_spam_score, referring_domains, referring_main_domains, referring_pages, referring_ips, referring_subnets, broken_backlinks, broken_pages, first_seen, lost_date.

Items1 <= items <= 3

limit?integer

Maximum number of records to return. Defaults to 100.

Range1 <= value <= 1000

offset?integer

Number of records to skip from the start of the results.

Range0 <= value

view?string

Value in"summary" | "full"
