Domain Registration

1. Check one domain

curl "https://domain.kmerhosting.com/api/domain-search?domain=example.com"

2. Check several domains at once

curl "https://domain.kmerhosting.com/api/domain-search?domains=example.com,example.net,example.org"

3. Call it from JavaScript

const res = await fetch(
  "https://domain.kmerhosting.com/api/domain-search?domain=example.com"
)

if (res.status === 429) {
  const wait = Number(res.headers.get("Retry-After"))
  throw new Error(`Rate limited, retry in ${wait}s`)
}

const { results } = await res.json()
for (const { domainName, registrar, price } of results) {
  console.log(
    domainName,
    registrar.status, // "available" | "unavailable" | "unknown" | "unsupported"
    price?.registration_price_usd
  )
}

Good to know

• Up to 20 unique domains per request.
• Each IP address can make 20 requests per 60 seconds. A 429 response includes a Retry-After header.
• Results include availability (registrar.status), the live price and renewal/transfer prices.
• The API only checks availability. Register and manage domains in the KmerHosting dashboard.
