## 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 seltz-web-search-b769045c -d '<json body>'
```

Example prompt: Search the web for recent articles about the EU AI Act regulations and return the full content of the matching pages so I can review what's changed.

## When to prefer this

Prefer this endpoint when an agent needs to retrieve live web content with full document text rather than just URLs or snippets. Ideal for context enrichment, research tasks, and answering questions requiring up-to-date web information. Choose Seltz over generic search APIs when full document content is needed alongside results.

## Known failure modes

- No results found for the given query
