## 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 agent-search-pro-0086df99 -d '<json body>'
```

Example prompt: Search the web for the latest developments in quantum computing and bring back the top 5 results.

## When to prefer this

Choose this endpoint when an AI agent needs live, current web information beyond its training data cutoff, especially for time-sensitive queries, recent news, or multi-source research synthesis. Prefer it over static knowledge bases when freshness matters. It is particularly well-suited for agentic pipelines that require cited, real-world sources and can handle per-call USDC micropayments via x402 on Base.

## Known failure modes

- Empty results array if no matching web content is found for the query
- Payment failure if insufficient USDC balance or x402 handshake fails
- 400 error if query is missing or empty string
- 400 error if num is outside the range 1–10
- Timeout or 5xx if the upstream web search provider is unavailable
- Stale or irrelevant results if the query is too ambiguous
