+## Vertex+
+
+[Vertex+](https://vertex-plus.asf.alaska.edu/ "https://vertex-plus.asf.alaska.edu" ){target=_blank} 
+is a separate deployment of ASF's Data Search Vertex interface, designed specifically for working with HyP3+. It 
+provides the same functionality as the standard deployment of Vertex, but is set to use the 
+[HyP3+ API Endpoint](#hyp3-api-endpoint "HyP3 API Endpoint Documentation"). 
+
+You can use the Vertex+ interface to search for available datasets, submit HyP3+ On Demand jobs for processing, 
+and access finished products. 
+
 ## HyP3+ API Endpoint
 
-HyP3+ has a different API Endpoint than the standard HyP3 Basic deployment:  
+The lowest-level interface for using HyP3 is the Application Programming Interface (API). All other access methods, 
+including Vertex and the HyP3 Python SDK, are built upon the 
+[HyP3 API](../using/api.md "Using HyP3 API Documentation"). 
+
+HyP3+ has a different API Endpoint than the standard HyP3 Basic deployment, so HyP3+ users will interact with the 
+following API URL:  
 <https://hyp3-plus.asf.alaska.edu>
 
 Users can interact with HyP3+ using the same methods as HyP3 Basic, but will need to change the API URL. 
-See the [Using HyP3](../using.md) section for more information on how to request On Demand products with HyP3+ using 
-[Vertex](../using/vertex.md#1-select-your-hyp3-api-optional "Jump to Using Vertex Documentation"), the 
-[HyP3 Python SDK](https://hyp3-docs.asf.alaska.edu/using/sdk/#connect-to-the-hyp3-api "Jump to Using SDK Documentation"), 
-or by using the [HyP3 API](../using/api.md "Jump to Using API Documentation") directly.

+or by using the [HyP3 API](../using/api.md "Using API Documentation") directly.
+
+You can also submit jobs to HyP3+ using the standard version of Vertex by 
+[updating the HyP3 API in Vertex](../using/vertex.md#hyp3-api-endpoints "Update API Documentation"). 
+It is more straightforward to use Vertex+ to interact with HyP3+ jobs, however, as it eliminates the

 # What's New
 
+## Apr 24, 2026
+
+**Effective April 24, monthly credit allotments for ASF’s HyP3 On Demand processing service will be reduced to 4,000
+credits per user per month.**
+
+Due to increased demand and recent changes to our operating costs, ASF no longer has sufficient processing capacity 
+to cover the current level of On Demand job requests. In recent weeks, processing requests have far outpaced our 
+system capacity, resulting in long wait times and unprocessed jobs for many users.
+
+To facilitate timely processing of all submitted jobs, we are reducing the monthly credit allotment 
+to 4,000 credits per user to better align request volume with processing capacity. Refer to the 
+[credit cost table](using/credits.md#credit-cost-table "Credit Cost Table") to determine the 
+number of products you can order per month. 
+
+ASF remains committed to providing On Demand processing within the constraints of our limited resources. We are making 
+this change to make sure all available processing time is used effectively and is equitably distributed. Refer to the 
+credit reduction post from [Nov. 26, 2025](#nov-26-2025 "What's New: Nov. 26, 2025") 
+for suggestions on processing options that use fewer credits. 
+
