Admin Endpoints

Philosophy

GoModel ships with admin endpoints enabled by default. The goal is simple: you should be able to deploy GoModel and immediately have visibility into what’s happening — no extra services, no separate monitoring stack, no configuration. The admin layer is split into two independently controllable pieces:

Admin REST API (/admin/*) — machine-readable JSON endpoints for usage data, budgets, and model inventory. Protected by GOMODEL_MASTER_KEY like all other API routes.
Admin Dashboard UI (/admin/dashboard) — a lightweight, embedded HTML dashboard that visualizes the same data. No external dependencies, no JavaScript frameworks to install — it’s compiled into the binary.

Both are on by default because observability shouldn’t be opt-in. If you don’t need them, turn them off with a single environment variable.

Configuration

Variable	Description	Default
`ADMIN_ENDPOINTS_ENABLED`	Enable the admin REST API	`true`
`ADMIN_UI_ENABLED`	Enable the admin dashboard UI	`true`

Or in YAML:

admin:
  endpoints_enabled: true
  ui_enabled: true

The dashboard UI requires the REST API to be enabled. If you set ADMIN_ENDPOINTS_ENABLED=false but leave ADMIN_UI_ENABLED=true, the UI will be automatically disabled with a warning in the logs.

Authentication

The admin REST API endpoints (/admin/*) are protected by the same GOMODEL_MASTER_KEY authentication as the main API routes. Include the key as a Bearer token:

curl -H "Authorization: Bearer $GOMODEL_MASTER_KEY" \
  http://localhost:8080/admin/usage/summary

The dashboard UI pages (/admin/dashboard) and static assets (/admin/static/*) skip authentication so the dashboard is accessible without configuring API keys in the browser.

If your GoModel instance is publicly accessible, be aware that the dashboard UI is unauthenticated. Disable it with ADMIN_UI_ENABLED=false or restrict access at the network level.

REST API Endpoints

All admin API endpoints are mounted under /admin.

Legacy path alias — until 2026-08-09, the same endpoints are also reachable under /admin/api/v1/*. Responses on the legacy path carry Deprecation: true, Sunset: Sun, 09 Aug 2026 00:00:00 GMT, and a Link header pointing to the new path. To migrate, replace /admin/api/v1/ with /admin/ in your scripts. One endpoint also moved within /admin: /admin/api/v1/dashboard/config → /admin/runtime/config.

GET /admin/usage/summary

Returns aggregate token usage statistics over a configurable time window. Query parameters:

Parameter	Type	Description	Default
`start_date`	string	Range start in `YYYY-MM-DD` format	29 days before end
`end_date`	string	Range end in `YYYY-MM-DD` format	Today
`days`	int	Shorthand for look-back window (ignored if dates are set)	`30`

Use start_date/end_date for explicit ranges or days as a shorthand. When both are provided, start_date/end_date take priority. Response:

{
  "total_requests": 1542,
  "total_input_tokens": 2450000,
  "total_output_tokens": 890000,
  "total_tokens": 3340000
}

If usage tracking is disabled, returns zeroed values.

GET /admin/usage/daily

Returns per-period token usage breakdown over a configurable time window, grouped by the specified interval. Query parameters:

Parameter	Type	Description	Default
`start_date`	string	Range start in `YYYY-MM-DD` format	29 days before end
`end_date`	string	Range end in `YYYY-MM-DD` format	Today
`days`	int	Shorthand for look-back window (ignored if dates are set)	`30`
`interval`	string	Grouping: `daily`, `weekly`, `monthly`, `yearly`	`daily`

The date field in the response changes format based on the interval: YYYY-MM-DD (daily), YYYY-Www (weekly), YYYY-MM (monthly), or YYYY (yearly). Response:

[
  {
    "date": "2026-02-17",
    "requests": 84,
    "input_tokens": 120000,
    "output_tokens": 45000,
    "total_tokens": 165000
  },
  {
    "date": "2026-02-16",
    "requests": 102,
    "input_tokens": 155000,
    "output_tokens": 58000,
    "total_tokens": 213000
  }
]

Returns an empty array if usage tracking is disabled or no data exists for the period.

Budget endpoints

Budgets are managed under /admin/budgets. These endpoints are available when budget management is enabled.

Method	Path	Description
`GET`	`/admin/budgets`	List budgets with current status
`PUT`	`/admin/budgets/{user_path}/{period}`	Create or update one budget
`DELETE`	`/admin/budgets/{user_path}/{period}`	Delete one budget
`GET`	`/admin/budgets/settings`	Read budget reset settings
`PUT`	`/admin/budgets/settings`	Update budget reset settings
`POST`	`/admin/budgets/reset-one`	Reset one budget period
`POST`	`/admin/budgets/reset`	Reset all budget periods

PUT, DELETE, and reset-one identify one budget by the composite (user_path, period) key, or (user_path, period_seconds) for custom periods. These operations are not global per period. For the path-scoped PUT and DELETE routes, URL-encode user_path; see Budgets for the request shape. See Budgets for request examples and enforcement behavior.

GET /admin/models

Returns all registered models with both provider type and configured provider name. Response:

[
  {
    "model": {
      "id": "gpt-4o",
      "object": "model",
      "created": 1715367049,
      "owned_by": "system"
    },
    "provider_type": "openai",
    "provider_name": "openai_primary",
    "selector": "openai_primary/gpt-4o"
  },
  {
    "model": {
      "id": "claude-sonnet-4-5-20250929",
      "object": "model",
      "created": 1727568000,
      "owned_by": "system"
    },
    "provider_type": "anthropic",
    "provider_name": "anthropic_main",
    "selector": "anthropic_main/claude-sonnet-4-5-20250929"
  }
]

This differs from the standard /v1/models endpoint: the admin version includes both provider_type and provider_name for each model, making it useful for understanding both the provider family and the concrete configured provider instance that serves the model.

Admin Dashboard

The dashboard is a server-rendered HTML page embedded in the GoModel binary. Access it at:

http://localhost:8080/admin/dashboard

It provides a visual overview of usage statistics and registered models using the same data as the REST API endpoints above.

Disabling Admin Features

To disable all admin features:

export ADMIN_ENDPOINTS_ENABLED=false

This disables both the REST API and the dashboard UI. To keep the API but hide the dashboard:

export ADMIN_ENDPOINTS_ENABLED=true
export ADMIN_UI_ENABLED=false

The admin layer is designed to degrade gracefully. If usage tracking is off, the usage endpoints return empty results instead of errors. If the model registry isn’t ready, the models endpoint returns an empty array. The gateway keeps running regardless.
