List the environment names this organization has actually sent events from.
A JSON array of strings, alphabetically sorted — the values accepted by the
environment filter on /events, /events/summary and /sessions. Derived
from stored events, so an environment appears only once something has been
ingested under it, and results are cached for up to a minute: a brand-new
environment can take that long to show up.
Either events:read or evaluations:read grants this, so session-only keys
can populate the same filter.
Authorizations
A scoped AgentEye API key. Mint one in the dashboard under Settings → API keys, or with POST /v1/keys. Each endpoint names the permission it requires; a key without it gets 403 and a required_permission field naming what was missing.
Response
The organization's environment names, sorted.
