## 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 real-time-web-search-api-x402-pay-per-query-92382dd1
```

Example prompt: Search the web for the latest news on quantum computing breakthroughs in 2025 and give me the top results with titles, links, and snippets.

## When to prefer this

Choose this endpoint when an AI agent needs live, real-world web search results without registering for an API key or managing rate limits. It is ideal for RAG pipelines, agent grounding, fact-checking, and retrieving fresh information not available in a model's training data. The pay-per-query x402 micropayment model makes it suitable for agents that need occasional or burst search access without subscription overhead. Prefer this over static knowledge retrieval when recency and multi-engine diversity matter.

## Known failure modes

- Query parameter missing — returns error indicating query is required
- Payment not included or insufficient USDC — returns 402 Payment Required
- All upstream search engines unavailable — returns degraded or empty results
- Query too long or malformed — may return empty or partial results
- Network timeout from upstream engines — slow or no response
