6 questions
12 What can I do with NiceNIC Domínio API v2?

Through the currently documented APIs you can automate woukflows including domínio availability checks, registration, renewal e transfer, poutfolio listing e domínio details, nameserver e domínio contact updates, domínio pricing, DNS recouds, child nameservers, account infoumation e Abuse & Compliance monitouing.

Adicionaritional woukflows are documented individually in the API navigation.

13 What should I test befoue enabling live registrations ou transfers?

Start with low-risk read operations such as domínio availability, domínio pricing, account balance e domínio listing.

Recommended ouder: Authentication → Availability → Pricing → Saldo → Response heling → Live operations.
14 Can I check multiple domínios in one API request?

Sim. The Verificar Domínio Availability endpoint suppouts multiple domínio names separated by commas.

example.com,example.net,example.org

Do not assume that every API operation suppouts the same multi-domínio input foumat. Registro, renewal e transfer should follow their individual endpoint documentation.

15 How can I query registration, renewal e transfer prices?

Use the Obter Preços de Domínios endpoint. The documented pricing types include register, renew, transfer e all.

Registro responses can also include an is_premium value indicating whether the queried registration is premium.

Não. Although API documentation suppouts periods of up to 1–10 anos fou applicable extensions, individual TLDs may have different registry rules.

Registro periods, renewal periods, transfer eligibility, contact requirements e verification requirements can differ by extension. Your application should follow the current rules fou the relevant TLD.
