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 agent-preflight-batch-multi-url-preflight-analysis-ebf3ba1b -d '<json body>'
```

Example prompt: Before my agent swarm starts crawling, run batch preflight on these URLs — https://shop.example.com/products, https://api.example.com/v2, https://portal.example.com/login — and tell me which ones have CAPTCHAs or login walls, what APIs are discoverable, and whether any content has changed since last check.

## When to prefer this

Use this endpoint when you need to pre-screen multiple URLs in a single call before dispatching an agent or agent swarm — especially when you need to know upfront which URLs have login walls, CAPTCHAs, discoverable APIs, or recent content changes. Prefer it over single-URL tools when operating at scale or coordinating multi-agent workflows that require access intelligence before committing to crawl or scrape operations.

## Known failure modes

- Invalid or malformed URLs in the batch return per-URL failure entries
- Network timeout reaching a target URL results in that URL marked as failed
- Payment not fulfilled causes 402 rejection before processing begins
- Empty or missing 'urls' field causes a 400 bad request
- Rate limiting on target sites may result in incomplete preflight data for some URLs

## How this service works

## Output

A JSON object containing a batch summary (total URLs processed, succeeded, failed) plus per-URL preflight results covering CAPTCHA/login detection status, discovered API endpoints, product intelligence signals, and change monitoring flags.
