@domainkits/sdk

TypeScript client for the DomainKits REST API.

This is the official TypeScript SDK for the DomainKits API, published and maintained by the DomainKits team. DomainKits is built and operated by Lyalpha GmbH, with domain data and infrastructure provided by ABTdomain, our domain intelligence and data aggregation platform. This repository is hosted under the ABTdomain GitHub organisation. Learn more about the relationship at domainkits.com/about.

Every parameter, response field and current limit is documented in the API reference and the OpenAPI spec. This README only lists what the SDK covers.

Requirements

The REST API is for Premium and Platinum accounts; unauthenticated requests are rejected with 401. Keys start with dk_ and come from domainkits.com.

If you want a no-key way to explore the same data from an AI client, use @domainkits/mcp instead, which has a guest tier.

Install

npm install @domainkits/sdk

Usage

import { DomainKits } from '@domainkits/sdk';

const dk = new DomainKits(process.env.DOMAINKITS_API_KEY!);

const { data, total } = await dk.nrds.list({ query: 'shop', tld: 'com' });

Endpoints

Search resources, each with list, paginate and export:

Resource	Endpoint
dk.expired	/search/expired
dk.nrds	/search/nrds
dk.nrdsLive	/search/nrds-live
dk.aged	/search/aged
dk.active	/search/active
dk.deleted	/search/deleted
dk.market	/search/market

Lookups and reports:

Method	Endpoint
dk.whois(domain)	/whois
dk.dns(domain)	/dns
dk.bulkDns(domains)	/bulk/dns
dk.bulkWhois(domains)	/bulk/whois
dk.ipLookup(query)	/ip-lookup
dk.registrar(query)	/registrar
dk.statusGuide(query)	/status-guide
dk.tldCheck(params)	/tld-check
dk.typosquat(params)	/typosquat
dk.nsReverse(params)	/ns-reverse
dk.monitorChanges(params)	/monitor/changes
dk.hostnameSearch(params)	/search/hostname
dk.ctSubdomains(domain)	/ct/subdomains
dk.ctCerts(params)	/ct/certs
dk.tldTrends(type)	/trends/tlds/*
dk.keywordTrends(type)	/trends/keywords/*
dk.nrdsDownload(params)	/nrds/download
dk.usage()	/usage
dk.searchStatus()	/search/status
dk.health()	/health

Parameters and result shapes are typed; the types mirror the API reference, which is the authority on every filter, field and limit.

No PII. Responses contain no registrant personal data.

Errors

import { RateLimitError, AuthError, DomainKitsError } from '@domainkits/sdk';

try {
  await dk.whois('example.com');
} catch (err) {
  if (err instanceof RateLimitError) {
    console.log('retry after', err.retryAfterMs, 'ms');
  } else if (err instanceof AuthError) {
    console.log('key rejected:', err.message);
  } else if (err instanceof DomainKitsError) {
    console.log(err.status, err.message);
  }
}

RateLimitError (429) carries the rate-limit headers and a retryAfterMs; the client retries 429 and 5xx responses on its own up to maxRetries before throwing.

Options

const dk = new DomainKits({
  apiKey: 'dk_...',
  baseUrl: 'https://premium-api.domainkits.com/api/v1',
  timeoutMs: 60000,
  maxRetries: 2,
});
