WHAT HAPPENS IF A NAME CAN BE MALE AS WELL AS FEMALE?
Depending on your API version or the integration you're using, our endpoints will either return an accuracy or a probability value in the response. The accuracy parameter returns how sure we are that this name is either male or female. The value is calculated by the number of records in our database. For example, if we have 100 samples of a name, 96 are female, and 4 are male, the accuracy is 96% (or a .96 probability). A low accuracy indicates that this name is probably used by multiple genders and cannot be conjugated to a specific gender.

CAN THERE BE DIFFERENCES FOR THE SAME NAME PER COUNTRY?
While the name Andrea is male in Italy, Andrea is a female name in Germany and can even be both in the US. In this case, we provide an accuracy value in the query result, ranging between 0 and 100 (or a probability value between 0 and 1). It tells you how certain we are in having detected the correct gender. You can significantly increase the API's result quality by providing some geographical information about your query. This can either be a country code, the browser's locale, or an IP address. You can learn more about localizing a query in our API docs.

HOW DO YOU GATHER THE DATA?
To provide the highest possible accuracy, we combine data from multiple sources. The main sources for new records are publicly available data, governmental data and manual additions/corrections. Based on the source of a new name, the name may have to be verified by a second source before it is added to our list. For example, if we add a name from publicly available data, this name may need a second verification, like a manual confirmation, before it is finally added to our database. You can find a list of supported countries here.

HOW OFTEN DO YOU UPDATE NAME RECORDS?
We regularly update our data depending on the country and the available public data. Most western countries are updated once a year. Also, the distribution of names across genders may change over the years. For example, if a name was used exclusively by women in the 1970s, it may be used predominantly by male people decades later. That's why we also use birth data for several countries, such as the US, to enrich the results. Our models try to take all these factors into account as well as possible. The returned accuracy value is regularly adjusted to reflect the actual usage in the population as accurate as possible. The value is supposed to provide a reasonable evaluation based on the last decades and may expresses a possible fluctuation. We do look at about the last 4 decades of the data. If you run a query and repeat the same query a year later, you may get a different result because our system might have dropped old data, and new data might have been added. Every time new data is added, we perform so-called integration tests afterward. In this process, our API is tested against a previously validated data set to ensure quality. This data set is continuously expanded with names and test cases to achieve the broadest coverage possible.

HOW DU YOU FACILITATE AI?
Artificial intelligence (AI) is being used to enhance the quality of our database and API results on a daily basis. With the help of AI, we can efficiently and accurately add new entries to our database, ensuring that our information is always up-to-date. Moreover, AI also plays a crucial role in improving the overall quality of our API results. By leveraging machine learning algorithms, we can analyze data more effectively, identify patterns, and provide more accurate and relevant results to our users.

DO YOU PROVIDE ANY HELP TO IMPLEMENT THE API?
Yes, we provide email support for all customers. You can email us to contact gender-api.com. We will then get back to you as soon as possible. You can also find coding examples here. Please note that we cannot help you with every programming language and use case. In most cases, you can use a standard rest client in your app to query our API. Many libraries also support the import of an OpenAPI definition file. You can download our openapi.yml definition file here.

WHAT IF WE NEED A HIGH LEVEL OF ACCURACY?
Languages and names are fluid and change over time. From customer to customer, data sets also vary a lot in quality, scope and origin. Therefore, we cannot guarantee that all results you receive from our API are 100% correct and match your data pool. But we can promise that we are always committed to providing you with the best results possible and that we regularly improve and update our algorithms. We also add new data on a very regular basis. You can find out more about our updates here. In the unlikely event of our service not matching up with your expectations, we give you a straightforward 14-day money-back guarantee. Of course, we also offer to test our service completely free of charge. If you sign up here, you will receive 100 requests for free every month. If you query a name, our endpoints will either return an accuracy or a probability value in the response, depending on your API version. The accuracy parameter returns how sure we are that this name is either male or female. The value is calculated by the number of records for this in our database. Since use cases differ significantly, we do not give any recommendations on the level of accuracy. Depending on your use case, it is up to you to decide what results and accuracy levels to accept. Even with an accuracy of at least 99%, there is a possibility that the result is incorrect. However, a value above 95% fits most use cases in general.

HOW MANY NAMES DO YOU HAVE STORED IN YOUR DATABASE?
Our database contains 6,084,389 validated names from 191 different countries. All over the world we store 6,196,452 unique names. On an average we analyze about 10,000,000 datasets per month to improve the quality of our results.

WHICH COUNTRIES ARE SUPPORTED?
The API fully supports 191 countries. Full support means that we collected at least names in this respective country. However, in most countries our dataset is much larger. Take a look at the following table to learn more about how many names we support in which country. Keep in mind that if we do not provide a suitable support for a country ourselves, you can still crawl the requested names against the entire dataset to get an adequate result.

DO YOU SUPPORT ARABIC NAMES?
Yes, our API supports Arabic names. They can also be written in chars from the Arabic alphabet. Arabic is written from right to left in a cursive style and includes 28 letters. As an example, if you query "عبد ال" you will get the following result: "gender": "male" , "accuracy": 100. The arabic name "عبد ال" is urlencoded in this example and the query url would look like: https://gender-api.com/get?name=%D8%B9%D8%A8%D8%AF%20%D8%A7%D9%84&key=YOUR_API_KEY. You can find a full list of supported countries here.

I HEARD ABOUT YOUR EMAIL API. WHAT EXACTLY IS IT?
Our email API can extract names from email addresses and provide the appropriate gender to this respective address. This can help you to personalize your emailings with a proper salutation. For example, from the email address "marie.johnson@gmail.com", API will extract the name "Marie" and determine the correct gender, which is "female". For details please take a look at our API Docs.

I HAVE A HUGE AMOUNT OF DATA. CAN I BULK UPLOAD A CSV FILE?
As a registered user you can upload any CSV file containing a first name column. For a better determination result, you can optionally add a country column to your dataset. While it is not necessary to specifically name the columns, our assistant guides you through the process by letting you choose which column contains which token, first name or country included. The feature is located within your account. Processed records will be charged like requests so that you can upload a CSV file with up to 100 entries for free every month. The CSV bulk upload requires a Gender-API.com account. For reasons of data protection, uploaded files will be automatically deleted after one year.

HOW NEEDS THE CSV FILE TO BE FORMATTED?
We support CSV files created on Windows, MacOS, or Linux. In addition, we support files with delimiters like ";", "," or a tab. The enclosure char must be a ". Furthermore, you can upload multi-line CSV files with a maximum of 10,000,000 rows and 301MB. We recommend using a UTF-8 formatted CSV file with a semicolon as the delimiter to achieve the best results possible. Otherwise, the CSV file can contain further, arbitrary rows, which will also be included in the output file. The file must have at least one column with first names only or a column with full names. Click here to download a sample file. Please create a Gender-API.com account to upload a CSV file.

CAN I UPLOAD AN EXCEL FILE?
You can upload Excel files with up to 300,000 rows. For larger datasets, please use our CSV file upload. We support .xlsx files with a single sheet. If you upload a file with more than one sheet, only the first will be processed. The first row in your sheet must contain the column names. The file must contain at least one column with first names, the country column is optional. For reasons of data protection, uploaded files will be automatically deleted after one year. Download sample file here. Example:
Excel Example

DO YOU PROVIDE ANY LIBRARIES FOR PROGRAMMING LANGUAGES?
Due to the simplicity of our API, we do not provide a lib for any programming language, except the jQuery Plugin. Most languages support a json parser out-of-the-box and for almost every other language, there is already an external lib you can use. Take a look at our coding examples to get started with using the API:
PHP with Composer PHP Legacy TypeScript JavaScript Python Java C#

First install our library with composer:

$ composer require gender-api/client
use GenderApi\Client as GenderApiClient;

try {
    $apiClient = new GenderApiClient('insert your API key');

    // Query a single name
    $lookup = $apiClient->getByFirstName('elisabeth');
    if ($lookup->genderFound()) {
        echo $lookup->getGender();      // female
    }

    // Query a full name and improve the result by providing a country code
    $lookup = $apiClient->getByFirstNameAndLastNameAndCountry('Thomas Johnson', 'US');
    if ($lookup->genderFound()) {
        echo $lookup->getGender();      // male
        echo $lookup->getFirstName();   // Thomas
        echo $lookup->getLastName();    // Johnson
    }

} catch (GenderApi\Exception $e) {
    // Name lookup failed due to a network error or insufficient remaining requests
    // left. See https://gender-api.com/en/api-docs/error-codes
    echo 'Exception: ' . $e->getMessage();
}

HOW DO REQUESTS GET COUNTED?
Every account will be recharged to 100 requests on the first day of every month if there are less than this number of requests left. Only if a result is found, the request will be counted. One name lookup will be counted as one request. If multiple names are requested in one query, each name will be counted as a single request.

WHERE CAN I FIND AND MANAGE MY API KEYS?
We generate an initial API key when you sign up for a Gender-API.com account. You can find this API key at the bottom of your account overview page. If you want to revoke this key, click on the "Revoke and Regenerate" button. Our system will then invalidate the existing API key and will generate a new one. All your applications that use the old token will then be unable to access our API until you replace this code with the new API key. Screenshot API key box You can also create more than one API key. This is useful, for example, if you have multiple applications in which you want to include our API. Please note there is no distinction between the keys and how many requests it has used. All requests are counted collectively. To manage or create multiple API keys, click on the "Settings" button in the account menu and then on "API Keys". Manage multiple API keys By clicking on the button "Create New Key", you can generate a new API key. You can give every token a name to later identify more easily where this key has been used. You can change this name at any time. Also, some of our widgets will auto-generate a key here. For example, if you use our "Quick Lookup Widget" in your account, our system will generate a key in advance, and this widget will then use this token to query our API. Furthermore, third-party apps will create a key here once they are connected. Every token can be revoked at any time by simply clicking on the "x". Once revoked, the connected application will no longer have access to our API.

CAN I SHARE MY ACCOUNT WITH MULTIPLE PEOPLE?
You can share your account with up to 50 more colleagues or other people connected to your project in your account. To manage your team, log into your account and, in the account menu, click on "Settings" => "Manage Your Team". On this page, click on the "Invite a new member" button to invite people via email to your team. When inviting members, you can choose between two different account types. A) Users can view, create, update and delete API keys, upload and genderize CSV and Excel files, access all API endpoints, buy requests and connect third-party apps. B) Administrators can do the same things users can, plus update account settings and billing address, create and view data processing agreements, invite, update and delete team members.

CAN I PROTECT MY ACCOUNT BY ENABLING TWO-STEP VERIFICATION?
You can protect your account by enabling two-step verification. To enable this additional security measure, log into your account and, in the accounts menu, click on "Settings" => "Change Password / 2FA". Make sure you have an authenticator app installed on your phone. We recommend using an app like Authy (App Store, Play Store) or Google Authenticator (App Store, Play Store). Then click on the "Enable Now" button and follow the instructions on the screen. You can add multiple devices here to ensure, for example, that you still have access to your account after losing a device. Once enabled, you will be required to enter the generated code by your phone's authenticator app to log in successfully.

CAN I USE THIRD PARTY APPS WHEN TWO-STEP-VERIFICATION IS ENABLED?
Some integrations or third-party apps work flawlessly with two-step verification enabled. Others may require to connect without two-step verification. If you have problems logging into some app with your Gender-API.com credentials, log into your account on Gender-API directly and click on "Settings" => "Change Password / 2FA" in the account menu. Then click on the "Two-Step Verification" tab and set "Third-party app access" to "Not restricted". Please note, you can only change this setting if two-step verification is enabled.

WHAT IS THE DIFFERENCE BETWEEN A PAID AND A FREE ACCOUNT?
Both account types offer the same functionality. All API endpoints are available for both account types and will return the same results. Free accounts are limited to a certain amount of requests per month. When you sign up, 100 requests are immediately available to you for free. On the first day of each month, our system will reset this number, and the free requests will be available again. Please create only one account. If you need more requests, you can upgrade to one of our paid plans at any time here.

HOW CAN I LOGOUT FROM ALL DEVICES?
If you click the logout button in your account, you will only be logged out from your current device. To ensure the security of your account and data, it is important to log out from all devices when necessary. Please follow the instructions below to log out from all devices on our API platform successfully. When logged in, click here to logout from all devices. Also, if you change your password or modify your two-factor authentication settings, the system will automatically log you out from all devices that do not match your current IP address. This adds an extra layer of security to your account. Creating separate accounts for each team member is recommended to enhance safety and facilitate team collaboration. Furthermore, to enhance the security of your account, we strongly recommend enabling Two-Factor Authentication (2FA). This additional layer of protection adds an extra step to the login process, making it more difficult for unauthorized individuals to gain access.

WHAT IS THE DIFFERENCE BETWEEN A SUBSCRIPTION AND A ONE-TIME PAYMENT?
If you want to buy one of our packages, you can choose between a one-time payment, or subscribing to this package. Subscriptions are recommended if you want to use our service regularly. You can be assured that there are always enough remaining requests in your account. Requests purchased with a subscription can be used within one month. With an active subscription, our system will recharge your account after one month to the selected amount of requests. For example, if you are subscribed to our 25,000 requests package and have used 21,500, our system will replenish your account to 25,000 requests after one month. One-time packages can be purchased for a single use case and can be used within one year. For example, if you want to process an Excel or CSV file, we recommend the one-time purchase. One-time purchases do not renew. You have to make sure to not run out of requests. You can switch between both package types on our purchase page. Purchase Types Please don't mix both purchase types until you have talked to our support first or know exactly what you are doing. Buying a one-time package while you're subscribed to one of our packages can prevent the subscription from refilling your requests. For example, when there are more requests left from the one-time purchase, than the subscription would refill.

I NEED A CERTIFICATE OF RESIDENCE. CAN YOU ISSUE SUCH A CERTIFICATE?
If you need a certificate of residence from our company, please contact our support regarding your request. The certificate has to be individually requested for every company. Include in your request the full address of your company, your country of residence, and, if available, your tax number. The certificate of residence needs to be signed through our revenue office. It usually takes 2-3 weeks to receive the signed form, which we can then provide as a digital scan. Screenshot Certificate Of Resicence

HOW CAN I BUY A PACKAGE / MORE REQUESTS?
You can choose between either a subscription plan or a one-time-payment here. One-time-payment is recommended, if you want to process a large CSV file or if you prefer to use your requests on an irregular basis. You can charge your account with the required amount of requests at any time. Requests bought with one-time-payment can be used within one year. If you prefer to sign up for a subscription plan, your account will be refilled to the selected amount of requests every month. Subscriptions can be changed or canceled at any time.

HOW CAN I CANCEL MY SUBSCRIPTION?
You can change or cancel your subscription at any time here. If you want to stop your recurring payments, click on the "Cancel this subscription" button.
