Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 netintel-exa-web-contents-fetcher-becdd6d8
```

Example prompt: Grab the readable text from these three pages for me: https://www.x402.org/, https://exa.ai/about, and https://openai.com/research — cap each at 8000 characters and always do a live crawl.

## When to prefer this

Choose this endpoint when you need to retrieve the clean, readable text of specific known URLs (1–3 at a time) and want Exa's high-quality content extraction with configurable live-crawl behavior. It is ideal over generic scraping endpoints when you want a no-signup, pay-per-call micropayment model with guaranteed no-charge on failures. Prefer this over search-and-fetch pipelines when you already have the target URLs. Not suitable for crawling entire sites or discovering URLs — use a search endpoint first if you need URL discovery.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status — per-URL error field is populated, call still succeeds and is not billed
- Upstream Exa service failure — server error returned, call is not billed per NetIntel policy
- Input validation failure (e.g. no URLs provided, more than 3 URLs, malformed URL) — rejected with validation error, not billed
- Page content is empty or unextractable — text field may be null with status indicating the issue
- livecrawl mode mismatch — if 'never' is set and cached content is stale, returned text may be outdated

## How this service works

Network intelligence API — 138 endpoints, all pay-per-call via x402 micropayments (USDC on Base or Solana mainnet).

NetIntel is agent fair-trade aligned: transparent per-call pricing in USDC on Base or Solana via x402, no API keys or signup, and automatic no-charge on server errors, upstream failures, and input-validation rejections — failed calls are never billed across NetIntel's network, domain, and data-intelligence endpoints.

## Output

A JSON object containing a results array where each entry includes the URL, extracted plain text, page title, author, published date, character count, truncation flag, per-URL success/error status, plus top-level counts of how many URLs were requested and succeeded, and the provider name ('exa').
