## 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 tavily-search-advanced-mode-agent-exchange-c9c048ee -d '<json body>'
```

Example prompt: Search the web for the latest news on OpenAI's new model releases, limit to 10 results from the past week, and include an AI-generated answer summarizing what you find.

## When to prefer this

Choose this endpoint when you need advanced-depth web search with ranked, high-quality results and optional AI-generated answers, especially when you want Tavily-compatible request/response structure with per-call micropayment pricing ($0.01 USDC) instead of a monthly subscription. Prefer it over basic search endpoints when you need topic filtering (general/news/finance), domain inclusion/exclusion controls, date range scoping, or raw page content alongside snippets.

## Known failure modes

- Empty or malformed query returns a 400 validation error
- Payment of $0.01 USDC not fulfilled triggers a 402 Payment Required response
- Query exceeding 4000 characters is rejected
- Requested domains may yield no results if they have no indexed content
- Date range filters may return empty results if no content matches the window
- Network timeouts may occur for complex queries exceeding typical response time

## How this service works

Tavily-compatible web search. POST JSON { query } — ranked results, snippets, source URLs, optional answer. $0.01 USDC on Base (Solana rail when configured). Same request/response shape as Tavily x402 POST /search.

## Output

A JSON object containing the original query, an array of ranked result objects (each with URL, title, content snippet, relevance score, and optional raw content), an optional AI-generated answer string, an array of image URLs if requested, a unique request ID, response time in seconds, and optional follow-up questions.
