# List Subgraphs

`GET /v1/graphs/{graph_id}/subgraphs`

## Request

- Base URL: `https://api.robosystems.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.robosystems.ai/v1/graphs/{graph_id}/subgraphs`
- Auth: one of:
  - API key in header `X-API-Key`
  - HTTP bearer

## Path parameters

- `graph_id` string, required

## Response `200`

Successful Response

- ListSubgraphsResponse: Response model for listing subgraphs.
  - `parent_graph_id` string, required: Parent graph identifier
  - `parent_graph_name` string, required: Parent graph name
  - `parent_graph_tier` string, required: Parent graph tier
  - `subgraphs_enabled` boolean, required: Whether subgraphs are enabled for this tier
  - `subgraph_count` integer, required: Total number of subgraphs
  - `max_subgraphs` integer, nullable: Maximum allowed subgraphs for this tier (None = unlimited)
  - `total_size_bytes` integer, nullable: Combined on-disk footprint of all subgraphs in bytes
  - `total_size_mb` number, nullable: Combined size of all subgraphs in megabytes
  - `subgraphs` SubgraphSummary[], required: List of subgraphs
    - `graph_id` string, required: Full subgraph identifier
    - `subgraph_name` string, required: Alphanumeric name
    - `display_name` string, required: Human-readable name
    - `subgraph_type` 'static' | 'knowledge' | 'empty', required: Types of subgraphs.
    - `status` string, required: Current status
    - `size_bytes` integer, nullable: On-disk footprint in bytes — the database, its write-ahead log, and its vector index. Prefer this over size_mb at subgraph scale.
    - `size_mb` number, nullable: Same footprint in megabytes. Derived from size_bytes; kept for callers that render MB directly.
    - `created_at` string, date-time, required: Creation timestamp
    - `last_accessed` string, date-time, nullable: Last access timestamp
