But first,
What is sentiment analysis?
Sentiment analysis is the use of natural language processing, text analysis, computational linguistics, and biometrics to systematically identify, extract, quantify, and analyze emotional states and subjective information.
More simply put, it is the process of identifying and categorizing the emotional tone of a piece of text. It can be used to determine whether a writer's attitude is positive, negative, or neutral.
Why do developers need a sentiment analysis API?
Developers need to know about the best sentiment analysis APIs because they help developers understand the mood of their users. Developers can use these APIs to build analysis tools and reports for better insights and better decisions.
This article will cover the top sentiment analysis APIs. Developers should care about these APIs because they help developers understand the mood of their users. According to a study by Zendesk, 49% of users who are unhappy with a brand are likely to tell others about their bad experiences through social media (and then you’ll have to learn how to respond to Facebook ad comments that are not, frankly speaking, too nice for your brand). This is just one of many reasons why it's important for developers to understand the mood of their users.

Twinword Sentiment Analysis API
Twinword's Sentiment Analysis is an important tool for developers to use in order to determine a text's sentiment. This API can be useful if you have a large number of user responses or reviews and want to quickly find the negative comments to see what your customers don't like and vice versa. The score indicates how positive, negative, or neutral the overall text analyzed is. Anything below a score of -0.05 we tag as negative and anything above 0.05 is tagged as positive.
Any text analyzed with this API can be interpreted in different ways, so developers can create their own negative and positive minimum scores. Using the Twinword API can help developers make better products by understanding how customers feel about them.
Other features of their APIs include:
- text classification
- emotion analysis
- topic tagging
- text similarity
- word associations
- and much more
Pricing
This API has a pay-as-you-go pricing model, with different monthly request limits for each plan. The Basic Plan allows for 500 requests per month, while the Pro Plan allows for 125,000 requests per month. The Ultra Plan allows for 750,000 requests per month, and the Mega Plan allows for 2,000,000 requests per month.
Google Cloud Natural Language API
Google's Natural Language API is a powerful tool for developers that allows them to analyze and understand the data behind text with ease. The API can identify the sentiment of text, as well as the various entities within it. This information can be used by developers to create more intelligent applications that can better understand human language. Additionally, the API is part of Google's larger Cloud Machine Learning API family, which provides a wide range of machine learning tools and services. This makes the Natural Language API a valuable addition to any developer's toolkit.
The Cloud Natural Language API can also analyze sentiment directly on a file located in Cloud Storage. This eliminates the need to send the contents of the file in the body of your request. This makes it easier and faster for developers to get started using the API.
Google Cloud's natural language processing API can also be used for other tasks such as entity analysis and content classification. Entity analysis identifies specific entities within a text, such as people, organizations, or locations. This information can be useful for understanding the text as a whole. For example, if you were analyzing customer feedback, entity analysis could help you determine which aspects of the product people are most satisfied and dissatisfied with. Content classification assigns a category to a piece of text, such as news, sports, or entertainment. This information can be used to help organize and understand data behind text.
Pricing
Google Cloud's Natural Language API is priced based on the number of units analyzed. For every 1,000 Unicode characters in a document (including whitespace characters and any markup characters such as HTML or XML tags), one unit is charged. Prices for the usage of the API are computed monthly and vary depending on which feature of the API is used.
For sentiment analysis, the first 5000 units are free, then it goes up from there based on the pay-as-you-go pricing.
