# Referring domains, paged



## OpenAPI

````yaml https://api.surnex.io/docs/openapi.json get /v1/projects/{projectId}/backlinks/referring-domains
openapi: 3.1.0

  title: Surnex API
  version: 1.0.0
  description: >-
    The SEO platform's API.


    **The API is the product.** The dashboard is one client and the MCP server
    at `/mcp` is another. If a number needs deriving, a service derives it —
    never a React component, or the two clients drift.


    **Two kinds of auth.** The dashboard sends a Supabase access token as a
    Bearer JWT. MCP agents send `X-API-Key`, and the organization is resolved
    from the key.


    **Two data modes.** SERP results and Google Trends are fetched live on
    request. Everything else is written by the worker and read from Postgres, so
    a freshly-created project returns empty until its jobs complete.
