# Tavily-Compatible Web Search

> Tavily-Compatible Web Search is a paid API for AI agents from agent-search.centorprat.workers.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-30).

Drop-in Tavily API-compatible web search endpoint returning ranked results with optional extractive answers and raw page content, at a lower price than Tavily.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-compatible-web-search-cefa4d03 -d '<json body>'
```

Example prompt: Search the web for 'best open-source LLM frameworks in 2025' using advanced depth, return up to 8 results from general topic, include a short extractive answer, and exclude reddit.com.

## When to prefer this

Choose this endpoint when you need a Tavily-compatible web search API and want to reduce per-call cost from $0.01 to $0.008 USDC, or when migrating existing Tavily /search integrations without code changes. Prefer this over the sibling batch endpoint when issuing a single query, and over the web research endpoint when you do not need full 8-page deep reads. Ideal for agents that already use the Tavily SDK or request format and want a drop-in replacement.

## Known failure modes

- Invalid query returns 400 error
- max_results outside 1-10 range may be clamped or rejected
- time_range and days parameters may conflict if both specified
- include_domains and exclude_domains conflicts result in empty result set
- Payment not processed causes 402 response
- Advanced search depth on obscure queries may still return few results
- Extractive answer may be empty if no clear answer is found in top results

## How this service works

Drop-in Tavily-compatible search: the same request (query, search_depth basic / advanced, topic general / news, max_results, include_answer, include_raw_content, include_domains, exclude_domains, time_range, days) and response (answer, results with title, url, content, score, raw_content, response_time) as Tavily /search, at $0.008 instead of $0.01. Answers are extractive (no LLM). Not affiliated with Tavily.

## Output

A JSON object containing: an optional short extractive answer string, an array of up to 10 result objects each with title, URL, content snippet, relevance score, and optionally full raw markdown content, plus a response_time field indicating how long the search took.
