## 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 swerver-web-search-batch-api-7a14d9a3 -d '<json body>'
```

Example prompt: Can you fetch these three URLs for me — https://example.com, https://news.ycombinator.com, and https://techcrunch.com — and give me back the content of each one as clean Markdown?

## When to prefer this

Choose this endpoint when you need to scrape or fetch multiple URLs in a single round-trip to minimize latency and payment overhead. Ideal for agents that need to gather content from several pages simultaneously, want clean Markdown or plain text output without post-processing, or need JavaScript rendering and CSS selector targeting. Prefer over single-URL endpoints when you have 2+ URLs to process. No API key setup required — pay-per-use via USDC on Base makes it suitable for ad-hoc or low-volume automation.

## Known failure modes

- URL unreachable or returns non-200 status — individual result may contain error or empty content
- JavaScript evaluation failure on dynamic pages — JS errors may cause incomplete rendering
- Payment failure via x402 protocol — request blocked if USDC payment not completed
- CSS selector matches nothing — empty content returned for that field
- Stealth mode bypass failure on bot-protected sites — content may be blocked or captcha'd
- Batch too large — may hit size or rate limits causing partial failures
