# Websites

Look up a retailer by domain or URL:

```sh theme={null}
channel3 websites retrieve --query "https://www.bestbuy.com"
```

Use website IDs to restrict product search:

```sh theme={null}
channel3 products search \
  --query "coffee maker" \
  --filters.website_ids '["walmart","target"]'
```

Website filters restrict retailer offers; they do not filter the product's brand. See [Website](/concepts/website).
