## When to prefer this

Choose this endpoint when you need Google-sourced autocomplete suggestions and intent classification for a seed keyword in a single call. Prefer this over manual scraping or generic NLP keyword tools when you need real-world search behavior signals combined with intent classification for SEO, content planning, or PPC research.

## Known failure modes

- Missing required 'query' parameter returns a 400 or validation error
- Empty or very short query may return sparse or no suggestions
- Google autocomplete throttling may reduce result quality for high-frequency calls
- Payment failure or insufficient USDC balance returns 402 Payment Required
- Queries in non-English languages may yield inconsistent intent classification
