Example prompt: Can you pull up the redirect history for shopify.com using BuiltWith — I want to see all the past redirects and URL chains associated with that domain?

## When to prefer this

Use this endpoint when you need to understand the redirect history of a specific domain — useful for SEO audits, competitive intelligence, tracking domain migrations, investigating brand changes, or verifying whether a domain has historically redirected traffic elsewhere. Choose this over the general Domain Lookup when redirect chain data is specifically needed.

## Known failure modes

- Domain not found in BuiltWith database — returns empty or minimal result
- Invalid domain format in LOOKUP field — may return error
- API authentication failure — unauthorized response
- Truncated response for domains with very large redirect histories
- Network timeout for complex redirect chain lookups

## How this service works

Redirect history for a domain — inbound and outbound redirects with first/last detected dates.

## Output

Returns historical redirect data for the queried domain, including the chain of redirects associated with it as tracked by BuiltWith across 100M+ websites. The response is a potentially large object containing redirect history records.
