## 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 mesh-heurist-xyz-3afbf990 -d '<json body>'
```

Example prompt: Search the web for 'coinbase new token listings' from the past week and give me up to 5 summarized results with sources.

## When to prefer this

Use this endpoint when you need summarized, up-to-date web information with time filtering — especially for time-sensitive queries like recent news, past-week events, or site-specific lookups. Prefer over raw scraping endpoints when you want AI-digested summaries rather than raw HTML, and over static knowledge bases when freshness matters.

## Known failure modes

- Missing required search_term returns validation error
- Invalid time_filter value produces no time-filtered results
- Overly broad queries may return low-relevance summaries
- Rate limits or payment failures return 402 errors
- Site-specific operators on restricted domains may return no results
