x402
Hyrule Cloud Port Check is a paid API for AI agents from cloud.hyrule.host, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).
Checks whether a specific TCP or UDP port is open/reachable on a given host or IP, optionally grabbing a banner, from a selectable network vantage point

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
Returns a structured diagnostic response with a status (ok/info/warning/critical/error), a human-readable summary, a findings array with severity-coded messages and codes, the normalized target, partial flag, request ID, and timestamp. Optionally includes raw response data and a service banner if requested.
Example use cases
Verify SSH access on new VM
“I just spun up a new server at 203.0.113.42 — can you check if TCP port 22 is open and reachable, using the external monitor vantage so I know it's visible from the internet?”
Diagnose blocked SMTP port
“Can you check whether TCP port 25 is open on mail.mycompany.com from an external vantage? I'm worried our outbound mail is getting blocked somewhere.”
Test SIP port for VoIP setup
“Can you probe UDP port 5060 on voip.mydomain.net using the sip profile to see if the port is reachable? I need to know before I configure the phone system.”
Technical details
Endpoint
POSThttps://cloud.hyrule.host/v1/ports/checkWhen to prefer
Use this endpoint when you need an external, network-level port reachability check against a specific host and port number, especially when you want a structured severity-coded result and the option to choose your vantage point (external monitor, Hyrule AS215932, RIPE Atlas, Globalping, or system). Prefer it over generic ping tools when you need protocol-specific profiling (SSH, SMTP, SIP, HTTPS, etc.) or banner grabbing. It pays per-request in USDC via x402, making it suitable for agent-driven on-demand diagnostics without subscriptions.
Side effects
- Target is unreachable or filtered — status returns 'critical' or 'warning' with relevant finding codes
- Invalid port number (outside 1-65535) — validation error
- Target string too long or malformed — schema validation failure
- Timeout exceeded — returns error status if host does not respond within timeout_ms
- Unsupported protocol/profile combination — may return error or warning finding
- Payment not received — x402 payment required error before diagnostic runs
