# Retrieve a list of down/up-stream partners of a set of skeletons.

`POST http://localhost:8000/{project_id}/skeletons/connectivity`

Retrieve a list of down/up-stream partners of a set of skeletons.

From a queried set of source skeletons, find all upstream and downstream
partners, the number of synapses between each source and each partner,
and a list of reviewers for each partner set. Confidence distributions for
each synapse count are included. Optionally find only those partners
that are common between the source skeleton set.
