## 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 superhighway-web-search-cc269dbe
```

Example prompt: Search the live web for the latest news about OpenAI's new model releases from the past week and give me up to 10 results.

## When to prefer this

Choose this endpoint when an AI agent needs live, up-to-date web search results, especially for current events or recent news, and wants a pay-per-call model without a subscription. Ideal for agents that need real-time information retrieval with flexible recency filtering.

## Known failure modes

- Missing required 'q' parameter returns a validation error
- No results found for obscure or highly specific queries
- Recency filter may yield zero results if no content exists in that time window
- Rate limiting or payment failure if USDC balance is insufficient
- Network timeouts for queries that hit slow external search backends

## How this service works

Web search built for AI agents. Search the live web, pull recent news, and read any page as clean markdown — pay per call, free tier to start.

## Output

Returns a ranked list of web search results (up to 20) including page titles, URLs, and text snippets matching the query, optionally filtered by recency (day/week/month/year).
