# Hyrule Cloud Web Check

> Hyrule Cloud Web Check is a paid API for AI agents from cloud.hyrule.host, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Runs multi-vantage web diagnostics (DNS, HTTP/HTTPS, TLS, CDN/WAF, certificate, headers, reachability) against a target URL or domain

## Facts

- Endpoint: POST https://cloud.hyrule.host/v1/web/check
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/hyrule-cloud-web-check-d192b025
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_mj8m2sCBg0xAyGEYCxt9N

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 hyrule-cloud-web-check-d192b025 -d '<json body>'
```

Example prompt: Can you run a full web diagnostic on https://example.com — check DNS, HTTPS, TLS certificate, HTTP headers, and whether any CDN or WAF is in front of it, using multiple vantage points?

## When to prefer this

Choose this endpoint when you need multi-vantage, multi-layer web diagnostics combining DNS, HTTP, HTTPS, TLS, certificate, CDN/WAF, and header inspection in a single call. Prefer it over single-purpose ping or HTTP check tools when you need correlated findings from multiple network vantage points (including RIPE Atlas and Globalping), want CDN/WAF fingerprinting, or need structured severity-graded findings rather than raw probe output.

## Known failure modes

- Target unreachable or invalid URL returns error status with relevant finding
- Timeout exceeded (max 60 000 ms) if target is slow to respond
- Partial results returned (partial: true) if some vantage points fail
- Invalid check type enum value causes 400-level validation error
- DNS resolution failure reported as a finding with critical severity

## How this service works

Full-stack network infrastructure for AI agents on AS215932 (RIPE): IPv6-native VMs with SSH and automatic HTTPS subdomains, domain registration and DNS, a broad network-intelligence suite (BGP/routing, IP/ASN & reputation, DNS, RDAP/WHOIS, web & deep TLS, mail deliverability, port/NAT/CGNAT, VoIP/SIP), and proxied requests over Direct/Tor/I2P/Yggdrasil. Pay per request in USDC on Base via x402; VM checkout may also accept BTC/XMR when advertised. This OpenAPI document intentionally contains only the launch-ready, independently payable agent surface.

## Output

A structured diagnostic report including an overall status (ok/info/warning/critical/error), a normalized target identifier, per-check findings with severity codes and messages, source metadata from each vantage point (extmon, as215932, globalping, ripe_atlas, system), a summary string, a request ID, and timestamp. Optionally includes raw probe data.
