## When to prefer this

Use this endpoint when you specifically need redirect history and chain data for a domain from BuiltWith's extensive 100M+ website database. Prefer this over manual HTTP header inspection when you need historical redirect data rather than just current live redirect behavior, or when you need this data at scale as part of a competitive intelligence or SEO audit workflow.

## Known failure modes

- Invalid or malformed domain name returns an error or empty data object
- Domain not found in BuiltWith's dataset returns empty results
- Payment failure due to insufficient USDC balance
- Network timeout on redirect history retrieval
- Rate limiting if too many requests are made in a short period
