## 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 keyless-web-search-via-exa-ai-8c950482
```

Example prompt: Search the web for 'latest x402 protocol news' and give me the top results — titles, URLs, and snippets — I'll pay per query with no account needed.

## When to prefer this

Choose this endpoint when you need ad-hoc web search with no API key registration, no subscription, and want to pay only for what you use via USDC micropayments on Base. It is ideal for AI agents that need occasional or burst web lookups without committing to a search API plan, and for developers building x402-compatible workflows who want a ready-made search primitive powered by Exa.ai's neural search index.

## Known failure modes

- Invalid or empty query string returns no results or an error
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- Rate limiting or upstream Exa.ai outage causes a failed or delayed response
- Queries returning no indexed results yield an empty results array
- Malformed request missing the query parameter returns a 400-level error

## How this service works

Paid APIs with no signup. USDC on Base via x402.

## Output

A JSON object containing the original query string, the source attribution ('exa.ai'), the fetch timestamp, and an array of results — each with a URL, title, text snippet, and publication date — plus the price charged in USD for the call.
