## 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 forest-infra-http-health-probe-14fc17b9 -d '<json body>'
```

Example prompt: Can you do a quick HTTP health probe on https://api.example.com/status using a GET request and tell me the status code, whether it redirects, the content type, and response size?

## When to prefer this

Choose this endpoint when you need a lightweight, bounded HTTP health check that returns just the essentials — status, redirects, content type, and size — without full page scraping or deep content extraction. Prefer it over general web scraping tools when SSRF safety is required and you only need response metadata, not body content.

## Known failure modes

- URL fails SSRF protection check — private/internal IP ranges are blocked
- URL is malformed or does not match ^https?:// pattern — validation error returned
- Target server is unreachable or times out — connection error reported
- URL exceeds 2048 character limit — rejected with validation error
- Non-public or disallowed host results in probe refusal

## How this service works

Perform one bounded public HTTP health probe with status, redirects, content type and size basics. It uses central SSRF protection and does not duplicate full page scraping. Base mainnet USDC

## Output

Returns HTTP status code, redirect chain (intermediate and final URLs), content type header, and response size in bytes for the probed URL. Includes SSRF-protected bounded response metadata without full page content scraping.
