Getting started with our API
Welcome to Caravel's API documentation! Using Caravel's API you can
- Predict topics and intents
- Predict sentiment
- Predict emotions
That's not all. With Caravel's API you can get granular. Send over any text document to our API, one by one or in bulk, and Caravel's API will pre-processes your text analyzing for sentiment, emotions, and classifications down to the sentence level.
You can use any classifier you build in your Caravel account with our API – giving you the ability to leverage our prebuilt models, zero-shot classification, and trainable classifiers in your own code!
- Head over to your Workspace Settings by clicking on your team name in the left side nav.
- Click on the Account tab
- Click Generate Key and copy the key to your clipboard
This is the key you will use to make calls to Caravel's API. If at anytime you need a new key, click Regenerate Key and it will deactivate your old key and give you a new one.
Our API provides a global endpoint you can use if you only want to classify sentiment.

We also provide a similar global endpoint for predicting just emotions.

You can create your own text classifiers that you can use with Caravel's API to predict topics and intents.
post
/v1/classifiers/{classifier_id}
Classify
There are two type of text classifiers: Ensembles and Tags.
Ensembles classify without training data. With Ensembles you can combine any of the following techniques to classify text: keyword matching, prebuilt machine learning models, sentiment matching, and zero-shot classification (also known as inference).
Use Tag Classifiers to annotate text in your feed to train a classifier.
We offer a myriad of prebuilt classifiers in our library to help you get started right away.
Once you've created a classifier, you'll need the Classifier ID to use it with our API. Copy and paste the Classifier ID from the URL in your browser's address bar.
Be sure to input your Classifier ID and API Key in the follow examples.

If you need to classify more than one piece of text at a time, Caravel's API accepts multiple documents in the
texts parameter. Each document is classified asynchronously for high-speed performance when working with bulk data and the results are returned once all documents have been classified.Bulk classification is limited to 50 text documents at a time. If you need to classify more than this per request, please contact our support team at [email protected].
To classify in bulk, simply input multiple text documents into the
texts array in your request:cURL

Caravel's API makes fine-grain text analysis easy, enabling you to get the sentiment, emotions, and classified topics and intents of every sentence in a text document. Simply pass in
include_segments option to get sentence level insights and Caravel returns all your classifications down to the sentence.cURL
