Two corrections, both settled from Segment's published OpenAPI document
and their own client code rather than guessed.
The registration claimed the Public API exposes no workspace-name
endpoint on the token's scope. That is wrong: Get Workspace is the API
root, GET /, returning data.workspace.name for the workspace the token
is bound to — the base URL already encodes the US/EU region, so the URL
is the whole request. Without a resolver an organization running a prod
and a staging workspace saw two rows both named "Segment".
The per-user GET /users/{id} is what makes a large workspace exceed the
per-source budget, and it exists only to read permissions[].roleName.
Both endpoints return the same UserV1 schema, on which permissions is
declared but optional, so whether the list populates it is a server
behaviour no specification settles. Rather than assume, the list
response is now decoded for permissions and the per-user request is
issued only when the field is absent. Today Segment omits it — their own
Terraform provider's mock returns /users without permissions and
/users/{id} with them — so behaviour is unchanged; if that ever changes
the extra round trip disappears on its own. An empty-but-present array
is authoritative, meaning a user with no roles, not a missing field.
Page size stays at 200: the 1-1000 range is prose in the pagination
guide, the schema sets no maximum, and the migration guide says 200.
