We are excited to announce that the Sassbook Developer API for both content generation and content summarization is now publicly available. The text summarization API has been available for some time privately and was released a couple of months back. The text content generation API is now available, so the developer API now covers functionality of both web applications, the Sassbook AI Text Summarizer and the Sassbook AI Writer.
There has been tremendous interest in the capabilities that these web applications provide, so customers are able to incorporate them into their own workflows and custom applications. Many clients also needed to process large volumes of documents (especially for the Summarizer), so programmatic access was a requirement for them.
For content generation, it was about incorporating the capability into the customer’s applications and also about customizing how the snippet of text was being generated and presented to their users. Customers were also asking for a few other higher-level features, that we plan to incorporate into the API eventually.
Developer API Subscription Plans
Customers needing the API access varied in their usage patterns. Some of them were happy existing customers of the web applications but needed the API for some use cases. Others exclusively needed the API, but the volume of usage varied quite a bit.
In the end, we settled on two kinds of API plans:
- For the former group requiring both web-app access as well as the API access, there are free, monthly credits attached to each subscription plan. If the credits are exceeded, they are charged for the additional usage.
- For exclusive API access, the developer API plan is added. This plan features a free-trial and a one-time fee after the trial. Thereafter, the pricing is fully metered (usage-based) and charged monthly.
You can find the details of how these are structured in the Developer API page.
Developer API Documentation and Metered Pricing
Metered pricing is based on the amount of text processed, including both input and generated text. The pricing unit is 1000 tokens (1KT), which is about 750 words. The pricing is different for each API. As the volume of processing becomes higher, the per-unit pricing becomes lower for each subsequent higher tier.
For documentation and pricing of the specific API, please refer to their respective pages:

We think these APIs will serve those looking for simple, powerful, and highly-scalable AI content generation and AI text summarization quite well.
