A translation API is a software interface that allows developers to incorporate machine translation into their products. It enables applications to easily and quickly translate text from one language to another without storing or managing any translation data. It receives text in one language and returns the same text translated into another language. A translation API may also contain information about the source and target languages, such as the language used to create the original text.

A translation platform is a set of tools and services that enables a company or individual to translate their content into multiple languages. These platforms include a translation API and additional tools such as terminology management, human translation, and localization.
A translation API can be a valuable tool for software developers who want to include multilingual functionality in their applications. Translation API can translate between different character sets, such as ASCII and Unicode.
With the current increase in globalization, there is a need for the development of translation services that can remove language barriers that normally hinder effective communication between people.
Fortunately, there are several translation APIs that have been developed to make the process of translating web pages, phrases, and words painless.
What is Translation API?
A translation API can dynamically translate text between language pairs. State-of-the-art text translation APIs support thousands of language pairs. Translation APIs may also programmatically detect input language. These APIs are based on statistical machine translation and machine learning.
What’s more, some of the software have exposed their Application Programming Interfaces (APIs) to enable developers to integrate their features and incorporate translation capabilities into their own applications—without building them from scratch.
To assist you in making the best decision on the most suitable API to use, we reviewed several translation APIs based on the following four main criteria:
- API features: We evaluated the outstanding features of each of the translation APIs
- Supported languages: We assessed the languages that each of the APIs support.
- Pricing: We analyzed the cost of integrating each of the APIs into applications.
- Ease of use: We looked at the ease of using each of the APIs.
Eventually, we developed the following list of the top 10 best translator APIs:
- Google Translate API
- Microsoft Translation API
- Translate API
- Text Translation API
- SYSTRAN.io Translation API
- MyMemory Translation API
- My Translator Pro API
- Linguatools Translate API
- Yandex Translate API
- IBM Watson Language Translator API
