  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.

        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.
