Hi Ankur (and Tom),
We're glad you've been trying out the API. As we were spinning up the sandbox, we had invited a small number of "alpha partners" to try out the sandbox and documentation before we released them as openly as they are now. When we opened the sandbox to all Shared Savings Program ACOs, the alpha phase became open invitation as well--since you've already been working with the API in the sandbox, you're already working with us in alpha!
As the lead researcher on the project, I'd be interested to hear your reactions to what you've seen so far in the sandbox; please let me know if you'd be open to chatting and sharing your thoughts.
Warm regards,
Elissa Frankle Olinsky
BCDA Community Manager and UX lead
