Implementation Reference

• src/core/modules/backlinks/tools/backlinks-anchor.tool.ts:72-85 (handler)

  The handler function that implements the core logic of the 'backlinks_anchors' tool by sending a POST request to the DataForSEO Backlinks Anchors API endpoint and processing the response.

  async handle(params: any): Promise<any> {
    try {
      const response = await this.client.makeRequest('/v3/backlinks/anchors/live', 'POST', [{
        target: params.target,
        limit: params.limit,
        offset: params.offset,
        filters: this.formatFilters(params.filters),
        order_by: this.formatOrderBy(params.order_by)
      }]);
      return this.validateAndFormatResponse(response);
    } catch (error) {
      return this.formatErrorResponse(error);
    }
  }

• src/core/modules/backlinks/tools/backlinks-anchor.tool.ts:18-70 (schema)

  Zod schema defining the input parameters for the tool: target (required string), limit, offset, filters (array), order_by (array). Includes detailed descriptions.

    getParams(): z.ZodRawShape {
      return {
        target: z.string().describe(`domain, subdomain or webpage to get backlinks for
          required field
  a domain or a subdomain should be specified without https:// and www.
  a page should be specified with absolute URL (including http:// or https://)`),
        limit: z.number().min(1).max(1000).default(10).optional().describe("the maximum number of returned anchors"),
        offset: z.number().min(0).optional().describe(
          `offset in the results array of returned anchors
  optional field
  default value: 0
  if you specify the 10 value, the first ten anchors in the results array will be omitted and the data will be provided for the successive anchors`
        ),
        filters: z.array(
          z.union([
            z.array(z.union([z.string(), z.number(), z.boolean()])).length(3),
            z.enum(["and", "or"])
          ])
        ).max(8).optional().describe(
          `array of results filtering parameters
  optional field
  you can add several filters at once (8 filters maximum)
  you should set a logical operator and, or between the conditions
  the following operators are supported:
  =, <>, in, not_in, like, not_like, ilike, not_ilike, regex, not_regex, match, not_match
  you can use the % operator with like and not_like to match any string of zero or more characters
  example:
  ["rank",">","80"]
  [["page_from_rank",">","55"],
  "and",
  ["dofollow","=",true]]
  
  [["first_seen",">","2017-10-23 11:31:45 +00:00"],
  "and",
  [["anchor","like","%seo%"],"or",["text_pre","like","%seo%"]]]`
        ),
        order_by: z.array(z.string()).optional().describe(
          `results sorting rules
  optional field
  you can use the same values as in the filters array to sort the results
  possible sorting types:
  asc – results will be sorted in the ascending order
  desc – results will be sorted in the descending order
  you should use a comma to set up a sorting type
  example:
  ["rank,desc"]
  note that you can set no more than three sorting rules in a single request
  you should use a comma to separate several sorting rules
  example:
  ["domain_from_rank,desc","page_from_rank,asc"]`
        ),
      };
    }

• src/core/modules/backlinks/backlinks-api.module.ts:29-62 (registration)

  Registers the 'backlinks_anchors' tool (instantiated at line 32) by including it in the tools array and reducing to a record mapped by tool name, exposing description, params, and handler for MCP integration.
