## 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 search-reversesandbox-com-165360f7
```

Example prompt: Search the web for 'latest breakthroughs in fusion energy 2025' and give me the top 5 results — no tracking, no account needed, just clean JSON results.

## When to prefer this

Choose this endpoint when your agent needs real-time web search results without managing API keys, OAuth flows, or user accounts — especially in automated or privacy-sensitive pipelines where zero-logging and pay-per-query USDC billing are desirable. Ideal for agentic workflows that need structured JSON search results on demand without pre-registration.

## Known failure modes

- Payment not provided or insufficient USDC: returns 402 Payment Required
- Missing required 'q' parameter: returns 400 Bad Request
- count out of range (not 1-20): may return error or clamp to defaults
- Upstream search engine unavailable: may return partial results or 503
- Invalid offset value: may return empty results array

## How this service works

Private web search for AI agents — zero logging, no tracking, no human signup required. Pay-per-query with USDC, no API keys or accounts. Multi-engine JSON results. Pass q=query, optional count (1-20), offset.

## Output

A JSON object containing the original query, the engine used, the result count, and an array of web results each with a title, URL, and content snippet.
