# URL Normalizer API

> The URL Normalizer API cleans a URL into a canonical form, dropping paths, parameters, and scheme noise so the same site always resolves to the same value. Free to call, so you can run it across entire datasets.

<div id="cuf-use-cases" className="cuf-use-cases">
  ## Common Use Cases

  The same website written five different ways is five records your systems treat as different companies.

  * **Data Hygiene:** Canonicalizing website fields before storage.
  * **Deduplication:** Matching records that store the same site with different URLs.
  * **Enrichment Prep:** Producing clean domains to feed into enrichment endpoints.
  * **Analytics:** Grouping traffic and records by canonical site.
