*Information is presented in order of most test data. Data was sentences of 30-250 characters in length. Testing was only done on the most popular 100 languages. Testing showed near a 99% accuracy for majority of sentences at or above 300 characters in length.

FAQ:

How can I get perfect results?
Although you can’t get perfect results, the best accuracy (99%+ for many languages, even the lesser known ones) is seen at 300 characters or more. Regardless of text length, the longer the better.

What is the isReliable flag?
This means that the probability of the first language compared to the second is 0.9 or better, about the average confidence for the correct answers during testing.

What is the confidence value?
The confidence value is the difference between the first and second probability scores. Thus, it is a range from 0 to 1.

How many languages do we support?
We support 176.

How do I write this in a different computer language?
Please see the rapid api testing interface, the dropdown has multiple languages available.

I’m getting an error?
If it’s a 400 error, you are using the wrong request body values, see the api requirements. A “text” is required, however you don’t need “includePredictions”, it will be false by default.

How long does the request take?
Most requests take about 50 ms regardless of text size.

I’m having trouble setting up my API?
Make sure you have the proper headers, you need to set two different headers for rapid api, the host and the key.

I have many requests to make, what plan is best?
Plans are priced with the expectation that you will use the overage pricing. Please choose your plan pricing based on the overage cost, the bulk pricing is much more affordable for bulk request usage.
