Domain Expiration API Reference

Overview

Domain Expiration Checker works by analyzing the domain provided and checking the expiration date. It uses advanced algorithms to check the expiration date of the domain and returns the expiration date.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

GEThttps://api.apiverve.com/v1/domainexpiration

curl "https://api.apiverve.com/v1/domainexpiration?domain=myspace.com" \
  -H "x-api-key: your_api_key_here"

const res = await fetch('https://api.apiverve.com/v1/domainexpiration?domain=myspace.com', {
  headers: { 'x-api-key': 'your_api_key_here' },
});

if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);

const { data } = await res.json();
console.log(data);

import requests

res = requests.get(
    "https://api.apiverve.com/v1/domainexpiration?domain=myspace.com",
    headers={"x-api-key": "your_api_key_here"},
    timeout=15,
)
res.raise_for_status()

print(res.json()["data"])

package main

import (
	"fmt"
	"io"
	"net/http"
)

func main() {
	req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/domainexpiration?domain=myspace.com", nil)
	req.Header.Set("x-api-key", "your_api_key_here")

	res, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer res.Body.Close()

	out, _ := io.ReadAll(res.Body)
	fmt.Println(string(out))
}

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Parameters

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.

Parameter	Type	Description
`domain`Required	string	The domain to check the expiration date of domain

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

Sample response

{
  "status": "ok",
  "error": null,
  "data": {
    "domain": "myspace.com",
    "expirationDate": "2029-02-23T05:00:00Z",
    "daysToExpiration": 1164,
    "expirationStatus": "healthy",
    "createdDate": "1996-02-22T05:00:00Z",
    "lastUpdatedDate": "2023-01-17T00:16:21Z",
    "daysSinceLastUpdate": 1064,
    "domainAgeDays": 10890,
    "domainAgeYears": 29.8
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Field	Type	Example	Description
`domain`	string	`"myspace.com"`	The domain name checked for expiration
`expirationDate`Premium	string	`"2029-02-23T05:00:00Z"`	ISO 8601 timestamp of domain expiration date
`daysToExpiration`	number	`1164`	Number of days until domain expiration
`expirationStatus`	string	`"healthy"`	Domain health status: expired, critical, warning, healthy
`createdDate`Premium	string	`"1996-02-22T05:00:00Z"`	ISO 8601 timestamp when domain was created
`lastUpdatedDate`Premium	string	`"2023-01-17T00:16:21Z"`	ISO 8601 timestamp of last domain update
`daysSinceLastUpdate`Premium	number	`1064`	Number of days since last domain update
`domainAgeDays`	number	`10890`	Domain age in days (total lifespan)
`domainAgeYears`	number	`29.8`	Domain age in years with decimal precision

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted	A key restriction or IP allow-list; see key scoping.
`429`	Rate limited, or out of credits	Read `error` to tell them apart; see rate limits.
