## When to prefer this

Use this endpoint when you need to identify which keywords a domain has recently started gaining organic clicks on — ideal for tracking SEO improvements, monitoring competitor momentum, or discovering emerging keyword opportunities. Prefer this over general keyword tools when you specifically want to see positive click trajectory rather than overall rankings or keyword volume.

## Known failure modes

- Missing or invalid domain query parameter returns an error or empty result
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting if too many requests are made in quick succession
- Empty result set if no gained clicks keywords exist for the given domain
- Network timeout if the upstream SpyFu API is slow or unavailable
