# The magnitude-metric names under `scores.metrics`, each with its unit.

> Returns a JSON array of `{name, unit, count}` objects. Kept separate from
`score_keys` because the two are on different scales: score keys are 0-1
rates that share one axis, metrics carry units (ms, USD, tokens) and must not
be plotted against each other. `unit` is an empty string for metrics recorded
before units existed. Cached per organization for 60 seconds.

Note the underscore: the path is `/evaluations/metric_keys`.



## OpenAPI

````yaml /reference/openapi.json get /evaluations/metric_keys
openapi: 3.1.0
info:
  title: AgentEye API
  description: >-
    The AgentEye observability API.


    Every path below is relative to `/v1` on your deployment's dashboard origin
    — e.g. `https://app.example.com/v1/sessions`. Authenticate with a scoped API
    key as a bearer token.


    Organization scoping: a key belongs to one organization and acts on it
    automatically. An instance-scoped key selects one per request with the
    `X-AgentEye-Org` header; without it, such a key resolves to the default
    organization, so set it explicitly on a multi-org deployment.
