## 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-contents-api-a3602e6f -d '<json body>'
```

Example prompt: Can you fetch the full text and an AI summary of these three articles for me: https://example.com/article1, https://example.com/article2, and https://example.com/article3?

## When to prefer this

Use this endpoint when you already have URLs or Exa document IDs (e.g. from Exa Search results) and need the actual readable content — full text, highlights, or AI summaries — rather than just metadata. Prefer this over generic web scraping when you want clean, pre-processed text without HTML boilerplate, or when you need AI-generated summaries in the same call. Best used downstream of Exa Search to hydrate search results with content.

## Known failure modes

- Invalid or inaccessible URL returns empty or error for that item
- Exa document ID not found returns null content
- Paywalled or bot-blocked pages may return partial or no text
- Malformed URL array causes request validation error
- Large batches of URLs may increase latency or partial failures
