Postman is where many teams design, test and document an API. EndPointBlank answers a different question: which of your client organizations still call v1, and have they been told it is going away. You can use both.
Many API developers already know Postman. Its homepage says it is "trusted by over 50 million developers and 500,000 companies". Teams use it to build and send requests, keep collections of them, run tests and monitors, and publish documentation.
Its API versioning page describes versioning of the API's design: fork and merge collections, keep a revision history, and tag a collection to an API version so its mocks and monitors stay in step. Postman Insights adds an agent that runs beside your service and shows per-endpoint metrics and errors from live traffic.
If what you need is a shared workspace to design, test and document APIs, Postman does that, and EndPointBlank does not try to.
Deprecating v1
is not a design problem. It needs three answers: what state each version is in, which of your
customers still call it, and whether they have been told. Postman's versioning and Insights
pages describe versions of your collections and per-endpoint traffic. Neither describes
tracking which consumer calls which version, setting a retirement date, or telling those
consumers. Teams end up joining logs to a customer list by hand, the week before the
shutdown.
EndPointBlank records the calling client and the endpoint version on every authorization, so "who is still on v1" is a list. Mark a version deprecated in the portal and give it a date: every client still calling it sees Retires in 30 days on its provider page, with reminders 30, 7 and 1 day out.

EndPointBlank runs inside your services through a client library, so nothing about how you use Postman changes. Keep designing and testing in Postman. EndPointBlank checks each call against its client's grants, records the version it asked for, and tells the clients still on an old version when it is going away.
