What do "units" mean?

You can think of units like a sort of internal monetary systems. We offer different APIs, each one with a different cost in units. 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 ;-)

Product Units
Entity Extraction API 1 per request
Text Similarity API 3 per request
Language Detection API 0.1 per request
Sentiment Analysis API 1 per request

What are the extras?

Some APIs have optional functionalities that you may use in your request.

This means that the request is more complex and requires additional resources to be processed, so additional units per request may be billed. The table on the right lists all available extras that require additional units. These units will be added to the cost of the "standard" API request.

E.g., if you issue a request to the Entity Extraction API, with a text of 9000 chars and including 'top_entities' parameter, it will cost 4 units: 1 for Entity Extraction API, +1 for 'top_entities' parameter and +2 for long text.

Extra Units Applies to
top_entities parameter +1 per request Entity Extraction API
long texts,
(more than 4000 chars)
+1 every 4000 chars Entity Extraction,
Text Similarity,
Sentiment Analysis API
