## 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`):

## When to prefer this

Choose this endpoint when you need quick, up-to-date web research on shipping API comparisons specifically aimed at developers, without building a custom web scraper. It is ideal for discovery tasks where you want multiple source perspectives rather than a single authoritative answer. Prefer it over static databases when you need live web content and source attribution.

## Known failure modes

- No results found if query is too narrow or niche
- Stale or irrelevant snippets if the web index hasn't been refreshed
- max_results above 10 is rejected by the schema
- Network timeout if underlying web search is slow
- Payment failure if USDC balance is insufficient for the $0.01 fee
