Backlinks API features plenty of parameters that support custom filtration. By applying filters to your POST requests, you will be able to effortlessly extract data that matches your requirements. Note that we do not charge any fees for using data filtering or sorting rules.
Here you will find all the necessary information about filters that can be used with DataForSEO Backlinks API endpoints.
Note that filters are associated with a certain object in the result array, and thus should be specified accordingly. You can learn more about how to use filters in this help center article.
You will receive the full list of filters by calling this API. You can also download the full list of possible filters by this link.
As a response of the API server, you will receive JSON-encoded data containing a tasks array with the information specific to the set tasks.

Below you will find a detailed description of filters available in DataForSEO Backlinks API endpoints. You can specify up to 8 filters by using the and, or logical operators between the conditions.
Note: in Domain Intersection and Page Intersection endpoints the $key parameter refers to the variable denoting the sequence number of the page indicated in the targets array of the POST request;
for example, if you specify the pages in the POST request as follows: "targets":[
"https://football.com/news",
"https://fifa.com/updates",
"https://uefa.com/updates"]
the specified pages will be assigned with sequence numbers; e.g. the filter by the “https://fifa.com/updates” page will be assigned a “2” and will look as follows: "filters": ["2.domain_from","=","news24.com"]
Note #2: in Backlinks Anchors, Domain Pages and Domain Intersection endpoints you may come across empty-titled fields in the referring_links_semantic_locations array, which, however, are also available in filters. These empty fields are denoted as $empty and have the num type.
example: referring_links_semantic_locations.$empty
Note #3: in the following endpoints, you can filter the results by any top-level domain (TLD) from the referring_links_tld object of the response, but the structure of the filtered field is different:
In all cases, replace the $tld variable with the necessary TLD returned in the referring_links_tld object of the endpoint’s response. Example filter: "filters": ["1.referring_links_tld.com",">",0]

Description
filters
array
array of results filtering parameters
filters have the following structure: [filered_fieldfilter_operatorfilter_value] you can add several filters at once (8 filters maximum)
if you add more than one filter, you must set a logical operator and, or between the conditions
example: [["domain_from","=", "dataforseo.com"],"and",[["acnhor","like","%seo%"],"or",["texr_pre","like","%seo%"]]]
filtered_field
str

you can find all available filtered_field values here
Note: fields with an $empty mark are empty, but their values can still be filtered;
in the fields containing $key, this variable denotes the sequence number of the target indicated in the targets array of the POST request
filter_operator
str

available filter operators:
• if bool: =, <>
• if num: <, <=, >, >=, =, <>, in, not_in
• if str: like, not_like, ilike, not_ilike, in, not_in, =, <>

if you specify in or not_in operator, the $filter_value should be specified as an array
example: ["rank","in",[1,5]]
note that like and not_like operators require adding % symbol to get accurate results
example: ["anchor", "like", "%seo%"] return backlinks items that contain “seo” in the anchor field ["texr_pre", "not_like", "%seo%"] do not return backlinks items that contain “seo” in the text_pre field
