What does "unit" mean?

You can think of units like a sort of internal monetary systems. We will make available different APIs, each one with a different cost in credits. Units are not related to a single API, but to the wider system. Every API uses units from your daily or monthly vault.

The unit price for each single API depends on its nature. APIs can be billed by number of requests you make, by the complexity of your query, by the amount of data you need to crunch, ... well you got it ;-) 



What is the user data?

Dandelion API offers some functionalities that let the user customize the semantic engine. A user can create and use a custom list of spots to improve the accuracy of Dandelion API in specific contexts. He can also create and use a customized classifier models to categorize texts in his own taxonomy. Each user has a limited number of objects that can be used, as shown in the table on the right.

Product Units
Entity Extraction API 1 per request*
Text Similarity API 3 per request*
Text Classification API 2 per request*
Language Detection API 0.1 per request
Sentiment Analysis API 1 per request*
(+1 when using the url/html parameters)

* If the input text exceeds 4000 chars, it's billed an additional unit every 4000 chars (our APIs are optimized for short texts, and this size should suffice for most uses)
