## 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 gedx402-open-web-answer-search-d1de07b4
```

Example prompt: Search the open web and give me a cited answer to this question: 'What are the latest clinical trial results for GLP-1 weight loss drugs?' — check up to 5 sources.

## When to prefer this

Use this endpoint when an agent needs a grounded, cited answer from live open-web sources rather than a static knowledge base. Prefer it over general LLM completions when factual recency and source attribution matter. Ideal for research tasks, current-events questions, or any query where the agent must demonstrate its answer comes from real web pages. Requires x402-compatible USDC payment rather than a traditional API key.

## Known failure modes

- No relevant sources found for the query — returns empty or low-confidence answer
- max_sources exceeds allowed range (1-10) — likely a 400 validation error
- x402 payment not authorized or insufficient USDC balance — 402 Payment Required response
- Query too vague or ambiguous — low-quality synthesized answer with poor citations
- Web scraping blocked by target sites — fewer sources than requested returned

## How this service works

Exa Answer parity — one x402 POST searches the open web, batch-scrapes top sources, and returns a cited answer via chat/fast. $0.630 USDC per request. Agent search: answer, exa answer, research, open-web, cited answer.

## Output

A natural-language answer synthesized from up to 10 scraped web sources, with citations linking back to the original pages, returned via a chat/fast response format. Settlement is up to $0.63 USDC via x402.
