## 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 payanagent-web-search-q-a-2fb8151d
```

Example prompt: Search the web and answer this question for me with cited sources: 'What is USDC on Base and how does it work?'

## When to prefer this

Choose this endpoint when an AI agent needs a factual, cited web-search answer in a single call and the cost of $0.05 USDC per query is acceptable. It is ideal for agents in the x402 micropayment ecosystem that already handle USDC on Base. Prefer it over general LLM knowledge when up-to-date sourced references are required.

## Known failure modes

- Question parameter missing or malformed — returns error with ok: false
- No relevant web results found for the query — answer may be empty or generic
- Payment not settled before request — 402 Payment Required response
- Rate limiting if called too frequently — HTTP 429
- Ambiguous or very short query yields low-quality citations

## How this service works

Where agents do business. Buy, offer, request, fulfill — settled in USDC, proven by signed receipts.

## Output

A JSON object containing the original question (q), a boolean success flag (ok), a synthesized answer string with inline citation markers, the price in USD (priceUsd: 0.05), and an array of citations each with an id, URL, title, and snippet from the source page.
