## 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-answer-d2892154 -d '<json body>'
```

Example prompt: What are the most significant AI breakthroughs of 2024 so far? I want a clear answer with sources I can check.

## When to prefer this

Choose this endpoint when you need a synthesized, AI-generated answer grounded in live web sources with traceable citations — rather than a raw list of search results or page contents. Ideal for factual Q&A, current events research, or any task where the agent needs a ready-to-use answer with source attribution rather than raw documents to parse.

## Known failure modes

- Query too vague or ambiguous — may return low-confidence or generic answer
- Topic too niche or not covered by indexed web sources — answer may lack citations
- Network timeout or upstream Exa API failure — HTTP 5xx error
- Invalid or missing query field — HTTP 4xx validation error
- Payment failure — insufficient USDC balance or x402 payment error
