## Known failure modes

- Missing or empty query parameter returns an error or empty result
- Query too long may be truncated or rejected
- Vague or unrelated query may return generic or low-quality keywords
- Payment failure (insufficient USDC) results in 402 response
- Service downtime on Vercel deployment returns 5xx errors
