## 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 ysaere-agent-web-search-3b9c1a1a -d '<json body>'
```

Example prompt: Search the web for the latest news on US defense drone contracts in 2026 — give me up to 5 results filtered to the news category, with titles, URLs, and snippets.

## When to prefer this

Choose this endpoint when you need fast, cited, live web search results with optional content-type filtering (news, company, research paper, financial report, PDF, GitHub) and no account setup — ideal for agent workflows requiring pay-per-use web intelligence at $0.02 USDC per query. Prefer over general search APIs when you need source provenance via feed digest and category-scoped results.

## Known failure modes

- Query too short (under 2 chars) or too long (over 300 chars) returns validation error
- Invalid category value outside allowed enum returns error
- Payment not confirmed — empty results are not returned without successful USDC wallet payment
- No results found for highly specific or obscure queries
- Rate limits or upstream Exa search availability issues causing timeouts
