## 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 starchild-relay-brave-web-search-81b0cfab -d '<json body>'
```

Example prompt: Search the web for 'latest developments in quantum computing 2025' and give me the top results with titles and links.

## When to prefer this

Choose this endpoint when you need programmatic web search via the Brave Search engine, especially within an x402 micropayment context where per-call pricing ($0.00001 USDC) is acceptable and you want to avoid managing separate Brave API credentials. Useful when the Starchild Relay proxy is already in use for other data types and unified billing is preferred.

## Known failure modes

- 402 Payment Required – no or invalid X-PAYMENT header provided; agent must complete x402 payment challenge before retrying
- Empty results – query too vague or no matching pages found
- Rate limiting or upstream Brave API errors returning 5xx
- Malformed request – missing required 'q' field returns 400 error

## How this service works

All-in-one reputable data source for AI agents and developers. Crypto spot/OHLC, derivatives funding rates, open interest, liquidations, forex, commodities, indices, social sentiment, DeFi protocols, and more — 17+ upstream data sources behind a single x402 paywall.

Usage: Send requests to any proxied path (e.g. GET /coingecko/api/v3/...). Unauthenticated requests receive a 402 challenge with payment instructions. Include X-PAYMENT header with a valid signature to access data.

## Output

A list of web search results from Brave Search, including page titles, URLs, and text snippets matching the query — delivered after micropayment via the x402 protocol.
