How this service works
Check a package before install: malware, known vulnerabilities (OSV), exploited CVEs (CISA KEV) and end-of-life, plus LLM prices; signed answers, pay per call in USDC, no account or API key.
Output
Returns a JSON object containing the port number, a list of associated services (each with service name, transport protocol, description, and RFC reference), plus metadata including the dataset version date, staleness flag, IANA source URL, and retrieval timestamp.
Example use cases
Identify unknown open port
“I scanned a server and found port 8080 open — what is the official IANA service name and transport protocol assigned to it?”
Validate firewall rule service name
“We're writing a firewall rule for SSH — can you confirm the official IANA service name and which transport protocols are associated with port 22?”
Audit unexpected port in logs
“I'm seeing traffic on port 5353 in our network logs and want to know the official IANA assignment — what service and transport protocol is that?”
Technical details
Endpoint
GEThttps://g5joilnmeep4ntz3nwezxt5dmu.srv.us/v1/port/%7Bnumber%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, IANA-sourced service name and protocol information for a specific port number, especially in security auditing, network configuration, or firewall rule validation workflows. It is signed and pay-per-call with no account setup required, making it ideal for agent-driven automation that needs trusted, on-demand port lookups without committing to a subscription.
Side effects
- Port number not found in IANA registry — returns empty services list
- Invalid port number format — may return error or empty response
- Port above 65535 or non-integer input may be rejected
- Stale data flag set to true if dataset is outdated
- Payment failure via x402 protocol if USDC balance insufficient
