# 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.

The returned confidence distribution is a histogram with 5 entries, each one
representing a confidence value in the range [1,5], with 5 being the most
confident. A confidence distribution like [0,0,0,3,9] states that there are
3 links with confidence 4 and 9 links with confidence 5.

## Path parameters

- `project_id` string, required

## Response `201`
