## About

## What it does
Similar Domains finds websites related to a given domain name. Send a `domain` query parameter, and optionally set `limit` to control how many results you want back. The service exposes two GET endpoints: one for general similar-domain lookup, and one that returns similar sites by domain.

Use Similar Domains when you want to expand a competitor list, surface lookalike sites for market research, or recommend alternative destinations to users. A typical workflow is to check a known domain such as `shazam.com` and retrieve a bounded list of related sites for analysis or enrichment.

The response schema is open-ended, so the service returns a structured JSON object without promising specific fields beyond what the API provides. That makes it useful as a lookup layer in pipelines where you need domain similarity data, but do not want to hard-code a narrower shape.

Pair Similar Domains with enrichment, lead-scoring, or SEO workflows when you need a fast way to start from one site and explore nearby properties in the same space.
