**APIs profiled:** 10

Spaceship is a domain registrar and domain marketplace offering domain registration, DNS management, WHOIS privacy protection, and a SellerHub resale marketplace with SafePay escrow. Its public REST API (https://spaceship.dev/api, v1) exposes 40 operations across domain management, availability, settings, transfers, personal nameservers, contacts, DNS records, SellerHub, and asynchronous operations. Authentication uses a paired API key and secret (X-API-Key / X-API-Secret) with per-key scopes; long-running actions use an async-operation polling model (202 + a spaceship-async-operationid header polled at /v1/async-operations/{operationId}).
