Example prompt: Who are the top PPC competitors for shopify.com right now? I want to see which domains are running paid search ads on overlapping keywords.

## When to prefer this

Use this endpoint when you need to identify which domains are most actively competing against a target site in paid search (Google Ads/PPC), specifically when you want SpyFu's competitive intelligence data. Prefer this over the SEO competitor endpoint when the focus is on paid advertising overlap rather than organic search rankings.

## Known failure modes

- Missing or invalid domain parameter returns an error
- Domain not found in SpyFu database returns empty results
- Payment failure via x402 prevents API access
- Rate limiting may occur with rapid repeated calls
- Malformed query parameters return 400-level errors
