## When to prefer this

Choose this endpoint when building AI agents that need to discover and surface live public web information about customs tariff classification, HS codes, import duties, or trade compliance tools. Prefer this over static databases when you need fresh, real-world source links and snippets rather than structured tariff data. Best suited for agent builders researching available customs data resources rather than performing direct tariff lookups.

- Query too vague or unrelated to customs data — low-quality snippets returned
- Web pages unavailable or blocked — missing snippets for some sources
- max_results exceeds maximum of 10 — request rejected with validation error
