## 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 quantaflow-serp-brave-ai-mode-search-fc3a378e -d '<json body>'
```

Example prompt: Search Brave AI Mode for 'best open-source LLMs in 2025' and give me the AI-summarized results.

## When to prefer this

Choose this endpoint when you need AI-enhanced web search results (Brave AI Mode summaries) without managing a Brave Search API subscription, and your agent supports x402 micropayment protocol. Ideal for pay-per-use search in agentic workflows where you want current web information with AI summarization at $0.01 per query.

## Known failure modes

- Payment failure: insufficient USDC balance or wallet not configured for x402 protocol
- Invalid path or query parameters result in upstream 400/404 from Brave Search
- Brave Search API unavailability causes 502/503 passthrough
- Malformed JSON body causes request forwarding failure
- Rate limiting from upstream Brave Search API

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

The upstream Brave Search AI Mode response is passed through directly — typically includes AI-generated answer summaries, web result snippets, titles, URLs, and related search data in JSON format, after successful x402 micropayment of $0.01 USDC.
