## 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-news-search-paid-rag-synthesized-news-api-ddc185d0
```

Example prompt: Search TavilyX for news about the latest Federal Reserve interest rate decisions from the past 7 days and give me up to 10 results.

## When to prefer this

Choose this endpoint when you need up-to-date, web-scraped news results with RAG-synthesized context rather than static knowledge. It is ideal for agents needing recent headlines, breaking news, or current events on a specific topic, especially when freshness (lookback in days) and result count matter. Prefer this over general web search APIs when you want Tavily-quality news retrieval combined with NVIDIA NIM synthesis in a single paid call via x402 on Base.

## Known failure modes

- Missing required 'q' parameter returns a 400 or validation error
- Payment not provided or insufficient USDC triggers a 402 Payment Required response
- Query returns zero results if no recent news matches within the specified day window
- Invalid 'days' or 'limit' values (e.g. negative integers) may cause a 400 error
- Upstream Tavily or NVIDIA NIM service unavailability causes a 502 or 503 error
- Rate limiting or payment processing failure on Base blockchain delays response

## How this service works
