Fetch Secure Email Information API allows you to validate and analyze any email address with high accuracy and reliability. It evaluates multiple technical and security aspects, ensuring that emails are legitimate and functional. Among its capabilities, it checks whether the email format is valid according to standards, ensuring that the local-part@domain structure is correct. In addition, it verifies the existence of the domain and its MX records, determining whether the associated mail server can receive messages.

The API also analyzes SPF and DMARC records to identify email authentication policies and prevent spoofing or phishing. It detects whether the email address is on known blacklists, preventing contact with potentially malicious emails.

The API also detects suspicious parts of the email address and provides an overall trust rating. Each result includes information from associated TXT records, such as third-party verifications, SMIME certificates, or validation keys, adding an extra layer of technical verification.

Fetch Secure Email Information API FAQs

The Email Checker endpoint returns detailed validation results for an email address, including its format validity, domain existence, MX records, blacklist status, SPF and DMARC analysis, and an overall trust rating.

Key fields in the response include "validity" (indicating format correctness), "domain" (the email's domain), "mx_records" (mail server details), "blacklist_status" (if the email is flagged), and "trust_rating" (overall reliability score).

The Email Checker endpoint accepts parameters such as "email" (the email address to verify) and optional flags for detailed checks, like "include_spf" or "include_dmarc" to enhance the analysis.

The response data is structured in a JSON format, with nested objects for detailed checks. Each section corresponds to specific validation aspects, making it easy to parse and understand the results.

The API sources data from DNS records, public blacklists, and email authentication protocols (SPF, DMARC). This multi-source approach enhances the accuracy and reliability of the verification process.

Data accuracy is maintained through regular updates from authoritative sources, continuous monitoring of email validation standards, and automated checks against known blacklists and email authentication records.

Typical use cases include validating user sign-ups, preventing spam in marketing campaigns, ensuring reliable communication in business transactions, and enhancing security by filtering out suspicious emails.

Users can utilize the returned data by integrating it into their applications to filter out invalid or risky emails, improve user experience during registration, and enhance security measures against phishing attacks.

General FAQs

To obtain your API key, first sign in to your account and navigate to the API you want to use. From the API's Pricing section, choose a plan and complete the subscription process. Once subscribed, return to the API page and you will see your API Access Key displayed at the top of the documentation page. You can use this key to authenticate your requests.

You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.

The free trial lasts for 7 days and allows you to make up to 50 API requests.

No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.

Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.

Prices are listed in USD (United States Dollar), EUR (Euro), CAD (Canadian Dollar), AUD (Australian Dollar), and GBP (British Pound). We accept all major debit and credit cards. Our payment system uses the latest security technology and is powered by Stripe, one of the world's most reliable payment companies. If you have any trouble paying by card, just contact us at [email protected]

Additionally, if you already have an active subscription in any of these currencies (USD, EUR, CAD, AUD, GBP), that currency will remain for subsequent subscriptions. You can change the currency at any time as long as you don't have any active subscriptions.
The local currency shown on the pricing page is based on the country of your IP address and is provided for reference only. The actual prices are in USD (United States Dollar). When you make a payment, the charge will appear on your card statement in USD, even if you see the equivalent amount in your local currency on our website. This means you cannot pay directly with your local currency.
Occasionally, a bank may decline the charge due to its fraud protection settings. We suggest reaching out to your bank initially to check if they are blocking our charges. Also, you can access the Billing Portal and change the card associated to make the payment. If these does not work and you need further assistance, please contact our team at [email protected]
Prices are determined by a recurring monthly or yearly subscription, depending on the chosen plan.
API calls are deducted from your plan based on successful requests. Each plan comes with a specific number of calls that you can make per month. Only successful calls, indicated by a Status 200 response, will be counted against your total. This ensures that failed or incomplete requests do not impact your monthly quota.
Zyla API Hub works on a recurring monthly subscription system. Your billing cycle will start the day you purchase one of the paid plans, and it will renew the same day of the next month. So be aware to cancel your subscription beforehand if you want to avoid future charges.
To upgrade your current subscription plan, simply go to the pricing page of the API and select the plan you want to upgrade to. The upgrade will be instant, allowing you to immediately enjoy the features of the new plan. Please note that any remaining calls from your previous plan will not be carried over to the new plan, so be aware of this when upgrading. You will be charged the full amount of the new plan.
To check how many API calls you have left for the current month, refer to the 'X-Zyla-API-Calls-Monthly-Remaining' field in the response header. For example, if your plan allows 1,000 requests per month and you've used 100, this field in the response header will indicate 900 remaining calls.

You can monitor your API usage through the response headers included with every request:

x-zyla-api-calls-monthly-used: Shows the total number of API requests you have used during the current billing period.
x-zyla-api-calls-monthly-remaining: Shows the number of API requests you have remaining for the current billing period.

The 'X-Zyla-RateLimit-Reset' header shows the number of seconds until your rate limit resets. This tells you when your request count will start fresh. For example, if it displays 3,600, it means 3,600 seconds are left until the limit resets.

Yes, you can cancel your subscription at any time. Simply go to the Pricing section of the API you're subscribed to and click the "Unsubscribe" button.

Please note that upgrades, downgrades, and cancellations take effect immediately. Once your subscription is canceled, access to the service will end immediately, regardless of any remaining API calls in your quota.

After 7 days, you will be charged the full amount for the plan you were subscribed to during the trial. Therefore, it's important to cancel before the trial period ends. Refund requests for forgetting to cancel on time are not accepted.
When you subscribe to an API free trial, you can make up to 50 API calls. If you wish to make additional API calls beyond this limit, the API will prompt you to perform an "Start Your Paid Plan." You can find the "Start Your Paid Plan" button in your profile under Subscription -> Choose the API you are subscribed to -> Pricing tab.
You can contact us through our chat channel to receive immediate assistance. We are always online from 8 am to 5 pm (EST). If you reach us after that time, we will get back to you as soon as possible. Additionally, you can contact us via email at [email protected]
