expert.ai Natural Language API Pricing

Free of charge use

All the features of expert.ai Natural Language API can be used at no cost by any registered user without a paid subscription as long as the monthly usage is below 10M characters.
Once this limit is reached, no text can be submitted to the API until the beginning of the first day of the following month, when the monthly usage counter is reset.
To use the service without the limit, subscribe to a payment plan as described below.

There are two ways to subscribe to a service payment plan:

  • By choosing one or more plans from the Subscriptions page of the developer portal (https://developer.expert.ai/ui/subscriptions)
  • For AWS users, by choosing the expert.ai Natural Language API product from the AWS Marketplace catalog

In both cases, existing subscriptions are visible in the Subscriptions page of the developer portal, however AWS Marketplace subscriptions must be managed from the AWS console.

For AWS Marketplace pricing and subscription options, see the product page: https://aws.amazon.com/marketplace/pp/prodview-mzck3lrjdu3i2

Pricing for usage of our standard offering can be seen below.

Subscription plans from the developer portal

Pricing for the use of the expert.ai Natural Language API is computed monthly based on the amount of Content the Customer sends to the API for analysis in the preceding calendar month. On the first day of the next month, the credit card used for the subscription will be charged for the usage incurred in the preceding month. The entire amount of consumption will be charged at the corresponding tier. If the usage is below 10M characters, there will be no charge to subscribed users unless they are subscribed to the Media Bundle, in which case they will still pay the flat fee. Usage of the two Bundles is charged separately, so a user with a subscription to both will be charged for each one. Users can track their usage at https://developer.expert.ai/ui/dashboard/nlapi
