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-url-analysis-1a6df580
```

Example prompt: Before my agent tries to scrape https://example.com/pricing, can you do a preflight check on it with a 'research' intent to see if it has CAPTCHA, login walls, or bot protection that would block a direct fetch?

## When to prefer this

Use this endpoint when your AI agent needs to decide how to approach a URL before fetching it — especially when you need to avoid wasted browser-automation overhead, detect paywalls or login gates early, or route scraping tasks to the right fetching strategy. It is the right choice before any web-access step in an agent pipeline where the target URL's accessibility characteristics are unknown.

## Known failure modes

- Invalid or malformed URL returns a validation error
- Unreachable URLs return reachable: false with relevant HTTP status
- Network timeouts may return incomplete analysis with lower confidence
- Highly dynamic pages may produce lower confidence scores
- Rate limiting from target servers may affect analysis accuracy

## How this service works

Paid URL analysis, CAPTCHA and login detection, API discovery, product intelligence, change monitoring, and batch preflight for AI agents and agent swarms.

## Output

Returns a JSON object with: final resolved URL, page type classification, reachability boolean, HTTP status, content type, flags for CAPTCHA presence, login requirement, bot protection, and browser requirement, plus a recommended action string and a confidence score between 0 and 1.
