Endpoint
POSThttps://searchtav.vercel.app/rag/researchWhen to prefer
Choose this endpoint when you need a synthesized, narrative research report from live web content rather than raw search results. It is ideal when the user has multiple related questions that benefit from cross-source synthesis. Prefer this over raw search APIs when you want citations and a coherent written report in one call, and when your agent can handle x402 micropayments on Base for $0.12 USDC per call.
Side effects
- Payment not included or invalid x402 payment on Base — returns 402 Payment Required
- Queries array is missing or empty — returns 400 Bad Request with validation error
- Tavily upstream search failure — may return partial results or 502
- NVIDIA NIM synthesis timeout — returns 504 or truncated report
- Rate limiting if too many concurrent requests — returns 429
