# Network Ports API
> The official IANA Service Name and Transport Protocol Port Number registry as an API — 12,500+ TCP, UDP, SCTP and DCCP port assignments. Look up what service runs on a port (e.g. 443 → https), find which port(s) a named service uses (e.g. ssh → 22), and search the registry by service or description. A handy reference for networking, DevOps, security and firewall tooling.

## Authentication
All requests require your oanor API key in the `x-oanor-key` header. Get one at https://www.oanor.com/developer/keys.

```bash
curl -H "x-oanor-key: oanor_live_…" "https://api.oanor.com/netports-api/..."
```
