Availability and pricing
Check availability and price for one domain, or check availability for up to 200 domains at once. Read the MCP tools reference.
AiVikings.ai Developer Docs
AiVikings.ai is a domain registrar built for software and AI agents. It gives an agent a controlled way to discover domain availability, inspect pricing, register and renew names, manage nameservers and DNS, review contacts, and inspect the account behind each operation.
It is for agent builders who need domain actions inside an application, ChatGPT and Claude users who prefer plain-language workflows, domainers who need programmable portfolio operations, and hosting companies that need to connect customer onboarding to domain registration. The account holder remains responsible for purchase approval, registrant details, balance, and the final outcome of every paid operation.
There are three primary ways to connect. Use the MCP server when a compatible AI client can discover tools and complete OAuth. Use the REST API when your application needs ordinary HTTPS requests with a bearer token. Use the ChatGPT connector when you want to authorize an account and ask for a domain workflow in a conversation. The public Pricing API is also available for catalog browsing and domain-specific quotes before an account connection.
An end-to-end agent workflow starts by checking a proposed name, then reading the price and premium status before it spends account balance. After your application or the user approves the exact name, term, currency, contact, and spend, the agent can register one domain. It can read the resulting status and expiry, replace the full nameserver set, inspect DNS records, create or update records through the supported tools, renew a holding, and retrieve an EPP auth code for a transfer out. Each step has a separate tool or endpoint so read-only discovery does not automatically grant purchase authority.
For safe automation, begin with account identity, balance, availability, pricing, and status reads. Give paid registration, renewal, transfer, DNS write, and nameserver changes an explicit approval path in your application or client. A successful request is not by itself evidence that registry provisioning, DNS propagation, or a registrant verification task has completed. Read the domain back and keep the returned operation data with the workflow that initiated it.
The Quickstart shows the smallest REST flow. The MCP connection guide shows how an AI client discovers and authorizes the server. The operations reference records the supported REST paths, while the MCP tools reference lists tool parameters, returns, and risk levels.
