Synonyms and Antonyms Extractor API

Extract essential synonyms and antonyms instantly to elevate your vocabulary.

The Synonyms and Antonyms Extractor API is a linguistic tool designed for users who work with natural language processing (NLP). Its main function is to receive a word as a parameter and return a JSON structure with three essential fields: the word queried (word), a list of synonyms (synonyms), and a list of antonyms (antonyms).

The service allows you to enrich text and improve the quality of generated content, whether in tasks such as paraphrasing, semantic correction, searching for related terms, or vocabulary expansion. Thanks to its structured format, it can be easily integrated into web applications, mobile applications, or artificial intelligence systems that need to analyze or transform human language.

For example, when querying the word “elegant,” the API returns an extensive list of synonyms such as graceful, stylish, refined, or sophisticated, along with antonyms such as inelegant, tasteless, or unrefined. This level of detail is useful for writing tools, writing assistants, semantic recommendation engines, chatbots, or automatic proofreaders.

The API is designed to deliver accurate, fast, and consistent results while maintaining a clear and readable structure. Its main advantages include:

Overall, this API is an essential tool for semantic language enrichment, providing lexical intelligence to modern applications that rely on text comprehension and manipulation. Whether for more accurate writing, sentiment analysis, or developing artificial intelligence systems, the synonym and antonym API offers a powerful, versatile, and easy-to-implement solution.

Synonyms and Antonyms Extractor API FAQs

The API returns a JSON object containing three key fields: the queried word, a list of synonyms, and a list of antonyms. This structured data allows for easy integration into various applications.

The response includes three fields: "word" (the input word), "synonyms" (an array of words with similar meanings), and "antonyms" (an array of words with opposite meanings). This format facilitates quick access to relevant vocabulary.

The response is structured as a JSON object. It contains the queried word as a string and two arrays: one for synonyms and another for antonyms. This organization makes it easy to parse and utilize in applications.

The API provides synonyms and antonyms for any English word. This information is useful for enhancing vocabulary, improving writing quality, and supporting natural language processing tasks.

Common use cases include enhancing writing tools, developing chatbots, creating semantic recommendation engines, and improving automatic proofreaders. The API helps users find alternative words and enrich their text.

Users can customize requests by specifying any English word as a parameter in the API call. The API will return synonyms and antonyms specific to that word, allowing for tailored vocabulary enhancement.

The API sources its data from reputable linguistic databases and continuously updates its content to ensure accuracy. Quality checks are performed to validate the synonyms and antonyms provided.

If the API returns an empty list for synonyms or antonyms, it indicates that no relevant words were found. Users can handle this by implementing fallback strategies, such as suggesting related words or synonyms from a broader context.

General FAQs

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.

To see the maximum number of API requests your plan allows, check the 'X-Zyla-RateLimit-Limit' response header. For instance, if your plan includes 1,000 requests per month, this header will display 1,000.

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 plan anytime by going to your account and selecting the cancellation option on the Billing page. Please note that upgrades, downgrades, and cancellations take effect immediately. Additionally, upon cancellation, you will no longer have access to the service, even if you have remaining calls left in your quota.

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]

To give you the opportunity to experience our APIs without any commitment, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost. This trial can be used only once, so we recommend applying it to the API that interests you the most. While most of our APIs offer a free trial, some may not. The trial concludes after 7 days or once you've made 50 requests, whichever occurs first. If you reach the 50 request limit during the trial, you will need to "Start Your Paid Plan" to continue making requests. You can find the "Start Your Paid Plan" button in your profile under Subscription -> Choose the API you are subscribed to -> Pricing tab. Alternatively, if you don't cancel your subscription before the 7th day, your free trial will end, and your plan will automatically be billed, granting you access to all the API calls specified in your plan. Please keep this in mind to avoid unwanted charges.

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.

Payout Orders are processed between the 20th and the 30th of each month. If you submit your request before the 20th, your payment will be processed within this timeframe.
