When it comes to managing domains and ensuring the integrity of email communications, developers often find themselves choosing between various APIs. Two popular options are the Email Domain Checker API and the DNS Checker API. Each of these APIs offers unique features and capabilities that cater to different needs in the realm of domain management and email validation. In this blog post, we will delve into a detailed comparison of these two APIs, exploring their functionalities, use cases, performance, and ultimately, which API is best suited for specific scenarios.
Overview of Both APIs
Email Domain Checker API
The Email Domain Checker API is designed to validate email addresses, detect disposable emails, check DNS records (MX, SPF, DMARC, DKIM), and identify government and educational domains. This API is particularly useful for businesses and developers looking to ensure the quality and authenticity of their email data. By validating email formatting and assessing plausibility through domain and RFC compliance checks, it helps in reducing spam and fraudulent activities.
DNS Checker API
The DNS Checker API provides a comprehensive list of DNS records associated with any domain. It allows developers to retrieve essential information such as A, CNAME, MX, and NS records. This API is invaluable for optimizing network performance, diagnosing issues, and ensuring domain integrity. With its real-time data retrieval capabilities, it empowers developers to make informed decisions regarding domain security and reliability.
Feature Comparison
Email Domain Checker API Features
One of the standout features of the Email Domain Checker API is its Email Domain Analyzer. This feature allows users to send a GET request with an email address as a parameter and receive detailed information about its validity, authenticity, DNS records, and domain type.
For instance, when a developer queries the API with an email address, the response includes various fields such as:
- email: The email address being validated.
- is_valid: A boolean indicating whether the email is valid.
- is_temp_email: A boolean indicating if the email is from a disposable email provider.
- records: Contains DNS records like DKIM, MX, etc.
Here’s an example response from the Email Domain Analyzer:

DNS Checker API Features
The DNS Checker API features a powerful capability known as Get Records. This feature allows users to pass any domain and receive the DNS records associated with it. The API retrieves data directly from DNS servers through standard DNS queries, ensuring that the information is accurate and up-to-date.
When a developer queries the API with a domain, the response includes various DNS records such as:
- record_type: The type of DNS record (e.g., A, AAAA, MX, NS).
- value: The value associated with the DNS record.
- mname: The primary name server for the domain (for SOA records).
- serial: The serial number of the zone file (for SOA records).
Here’s an example response from the Get Records feature:
[{"record_type": "A", "value": "104.21.235.139"}, {"record_type": "A", "value": "104.21.235.140"}, {"record_type": "AAAA", "value": "2606:4700:3038::6815:eb8b"}, {"record_type": "AAAA", "value": "2606:4700:3038::6815:eb8c"}, {"record_type": "NS", "value": "jason.ns.cloudflare.com."}, {"record_type": "NS", "value": "lisa.ns.cloudflare.com."}, {"record_type": "SOA", "mname": "jason.ns.cloudflare.com.", "rname": "dns.cloudflare.com.", "serial": 2332122581, "refresh": 10000, "retry": 2400, "expire": 604800, "ttl": 1800}]This response structure provides developers with a comprehensive view of the DNS records, enabling them to diagnose issues and optimize network performance effectively.
