Technical details
Endpoint
GEThttps://searchtav.vercel.app/search/deepWhen to prefer
Choose this endpoint when you need both live web search results and a synthesized, coherent answer in one call — ideal for research tasks, current events, or fact-finding where you want more than a list of links. Prefer over generic search APIs when you need a RAG-style answer grounded in fresh web data, and over static knowledge bases when recency matters.
Side effects
- Missing required 'q' parameter returns 400 error
- Payment not provided or insufficient USDC triggers 402 Payment Required
- limit out of range (not 1-20) may return validation error
- Upstream Tavily or NVIDIA NIM outage causes 502 or timeout
- Vercel cold start may add latency on first call
