## 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 exa-web-search-via-apiosk-gateway-f4286b8e -d '<json body>'
```

Example prompt: Search the web for the latest research on large language model alignment and return the top results with their page contents using Exa's semantic search.

## When to prefer this

Prefer this endpoint when you need semantic (meaning-based) web search rather than exact keyword matching, or when you want page contents returned alongside search results in a single call. It is particularly useful for agents that need to understand conceptually related pages, not just keyword-matching ones. Choose this over generic scraping endpoints when you need ranked, relevance-scored web results.

## Known failure modes

- Invalid or missing query input returns a 400 error
- Payment not fulfilled via x402 protocol results in a 402 response and no search results
- Exa backend unavailability causes a 502 or 503 error
- Overly broad queries may return low-relevance results
- Pages with restricted content may return empty content fields even when contents are requested
