Use icann_transfer_lock_expires_at to tell a customer when the 60-day lock expires. can_transfer_out is true only when both are off; transferring out is done in the Atom dashboard, not via this API. ## OpenAPI ````yaml GET /registrar/v1/domains/{domain_name}/lock openapi: 3.0.3 info: title: Atom Registrar API version: 1.0.0 description: >- Domain registration, DNS, nameservers, contacts, transfers, TLD pricing, registrar lock, and renewal. Authenticate with a Registrar API Bearer token from https://www.atom.com/dashboard/seller/api-access Pricing: GET /domains/check/{domain_name} returns domain_price (what Atom charges to register that label, including premium) when the domain is available. GET /tld-pricing returns standard register / renew / transfer prices per TLD. Renewal: POST /domains/{domain_name}/renew renews a domain you already hold at Atom. Transfer in: POST /domains/transfer with domain_name + authcode. Optional nameservers, WHOIS privacy, auto-renew, contacts, and dns_records can be sent in the same request. Transfer out is not available via API. Unlocking a domain and retrieving an EPP / auth code must be done in the Atom dashboard. GET /domains/{domain_name}/lock still reports registrar lock and the ICANN 60-day lock expiry so you can tell a customer when a transfer-out will be possible in the dashboard. Transfer lock: GET/PUT /domains/{domain_name}/lock is the customer-controlled registrar lock. GET also returns icann_transfer_lock and icann_transfer_lock_expires_at for the automatic 60-day ICANN lock after registration or inbound transfer. Contacts: GET /contacts lists handles (filter with search, name, or email). GET /contacts/{handle} returns one contact.
