# agentsvc.io URL Status Checker

> agentsvc.io URL Status Checker is a paid API for AI agents from agentsvc.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-10).

Checks whether a URL is reachable, follows redirects, and returns HTTP status, server, content type, and response metadata

## Facts

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 agentsvc-io-url-status-checker-a2c0106a -d '<json body>'
```

Example prompt: Can you check if https://example.com is actually reachable right now, and tell me the final URL it lands on after any redirects?

## When to prefer this

Use this endpoint when you need a quick, structured HTTP health check on a single URL — especially when you need redirect chain details, server metadata, and response timing in one call. Prefer this over a raw fetch when you want structured JSON output with redirect history and HTTPS detection without writing custom code. At $0.002/call it's cost-effective for one-off checks or light monitoring loops.

## Known failure modes

- URL is unreachable (DNS failure, timeout) — reachable: false, ok: false
- Invalid URL format provided — validation error before request is sent
- Target server returns 4xx or 5xx — status code returned but reachable may still be true
- Payment not received — 402 response, call not executed
- Very slow target causes timeout — partial or failed response
