Technical details
Endpoint
POSThttps://searchtav.vercel.app/rag/queryWhen to prefer
Choose this endpoint when you need a single-step operation that both searches the live web and synthesizes a grounded answer with citations — ideal for research questions where freshness and sourcing matter. Prefer over static knowledge bases when current events or recent data are required, and over plain search APIs when you need a synthesized prose answer rather than raw search results.
Side effects
- Empty or missing query field returns a validation error
- Payment not completed via x402 results in 402 Payment Required
- Tavily search quota exceeded or upstream outage returns 5xx error
- NVIDIA NIM synthesis failure may return partial or empty answer
- No relevant web results found may yield a low-confidence or generic answer
