Example prompt: Show me the keyword overlap between hubspot.com and salesforce.com using SpyFu Kombat — I want to see which SEO and PPC keywords they both target so I can find the battleground terms.

## When to prefer this

Use this endpoint when you need to directly compare keyword footprints between two competing websites, especially when you want to find shared keywords that both sites rank for or bid on. Prefer this over general keyword research endpoints when the goal is competitive positioning, battleground keyword discovery, or understanding where two domains are fighting for the same audience in search results.

## Known failure modes

- Invalid or unrecognized domain names returns an error or empty result
- Domain with insufficient history in SpyFu database may return sparse results
- Rate limiting if too many requests are made in a short window
- Missing required domain parameters returns a 400 bad request
- Newly registered domains with no indexed keywords may return no overlap data
