About the API:
In corpus linguistics, part-of-speech tagging (POS tagging or PoS tagging or POST), also called grammatical tagging is the process of marking up a word in a text (corpus) as corresponding to a particular part of speech,[1] based on both its definition and its context. A simplified form of this is commonly taught to school-age children, in the identification of words as nouns, verbs, adjectives, adverbs, etc.
Pass any text to this API as a JSON, and receive all the possible tags for the different parts of the speech.
Use this API to retrieve semantic information from given texts.
Great API for Machine Learning training. Use the data to train your models so they can easily recognize different parts of the speech as well.
Besides API call limitations per month, there are no other limitations.
Tags the provided text with parts of speech (such as nouns, verbs, adjectives, adverbs, etc.).

The POS Tagging API returns a JSON object containing tagged parts of speech for each token in the provided text. The response includes fields such as "badRequest," "creditsUsed," "errors," and "sentences," where each sentence contains an array of tokens with their respective labels and confidence scores.
Key fields in the response include "badRequest" (indicates request validity), "creditsUsed" (number of credits consumed), "errors" (any processing errors), and "sentences" (array of sentences with tokens and their associated tags).
The response data is structured as a JSON object. It contains a top-level object with fields for request status and an array of "sentences," each containing "tokens." Each token includes "text" and "labels," where "labels" provide the part of speech and confidence score.
The API provides information on parts of speech for each word in the input text, including labels for nouns, verbs, adjectives, adverbs, and more. Each label is accompanied by a confidence score indicating the accuracy of the tagging.
Users can customize their requests by providing different text inputs in the JSON format. The API processes any valid text, allowing for flexibility in the type and length of text analyzed for part-of-speech tagging.
Typical use cases include natural language processing tasks, such as semantic analysis, text classification, and training machine learning models to recognize parts of speech. It can also be used in educational tools for teaching grammar.
Data accuracy is maintained through advanced algorithms that analyze context and definitions of words. The API uses machine learning techniques to improve tagging precision based on extensive linguistic datasets.
Users can expect a consistent structure in the response, with each token labeled according to its part of speech. Common patterns include multiple tokens per sentence, each with a label and score, facilitating easy parsing and analysis.

To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used 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.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
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.
Yes, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
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.
