# TavilyX — Paid Search + RAG API

> TavilyX — Paid Search + RAG API is a paid API for AI agents from searchtav.vercel.app, paid per call via x402, $0.04/call, status unknown (last checked 2026-09-15).

Accepts a natural language question, searches the live web via Tavily, and synthesizes a grounded answer using NVIDIA NIM RAG pipeline, returning both the query and a composed answer.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tavilyx-paid-search-rag-api-149b4145 -d '<json body>'
```

Example prompt: Search the web and give me a synthesized, grounded answer: what are the latest developments in quantum computing as of this year?

## When to prefer this

Choose this endpoint when you need a single, synthesized natural language answer grounded in live web content rather than a raw list of search results. It is ideal for factual Q&A tasks requiring current information not present in a model's training data, especially when paying per-query via x402 on Base is acceptable. Prefer alternatives if you need raw search result URLs, structured data extraction, or bulk queries.

## Known failure modes

- Empty or missing query field returns validation error
- Payment not completed via x402 results in 402 Payment Required response
- Tavily search API unavailable causes upstream failure with no answer returned
- NVIDIA NIM inference timeout results in incomplete or missing answer
- Query too vague or unsearchable may return a low-quality or empty answer
