# List agents
> Every agent in the workspace, filterable by state. Archived ones are hidden until you ask.
The [agents](/docs/api-reference/agentservice/create-a-new-agent) in a workspace, newest first. This is the read behind an agent picker or a dashboard.
```typescript TypeScript theme={null}
const agents = await client.agents.list({ workspaceId });
for await (const agent of agents) {
console.log(agent.metadata.name, agent.state, agent.info?.variationCount);
}
// Support Agent STATE_PUBLISHED 3
// Refund Agent STATE_DRAFT 1
```
```go Go theme={null}
agents := client.Agents.ListAutoPaging(ctx, cadenya.AgentListParams{
WorkspaceID: cadenya.String(workspaceID),
})
for agents.Next() {
agent := agents.Current()
fmt.Println(agent.Metadata.Name, agent.State, agent.Info.VariationCount)
}
```
```ruby Ruby theme={null}
agents = cadenya.agents.list(workspace_id: workspace_id)
agents.auto_paging_each do |agent|
puts "#{agent.metadata.name} #{agent.state} #{agent.info.variation_count}"
end
```
```bash cURL theme={null}
curl "https://api.cadenya.com/v1/workspaces/${WORKSPACE_ID}/agents" \
-H "Authorization: Bearer ${CADENYA_API_KEY}"
```
## Archived agents are hidden by default
The list returns `STATE_DRAFT` and `STATE_PUBLISHED` agents and **leaves archived ones out**. To see archived agents, ask for them by state:
```typescript theme={null}
const archived = await client.agents.list({ workspaceId, state: 'STATE_ARCHIVED' });
```
The `state` filter narrows to one state, and there are three you can pass:
| `state` | The agent is |
| ----------------- | ------------------------------------- |
| `STATE_DRAFT` | Created, not yet published |
| `STATE_PUBLISHED` | Live, and able to run objectives |
| `STATE_ARCHIVED` | Retired, hidden from the default list |
So `state: 'STATE_ARCHIVED'` is the only way to list archived agents, and `state: 'STATE_DRAFT'` is how you find the agents that still need a variation before they can [publish](/docs/api-reference/agentservice/publish-an-agent).
## `info` comes for free
Each row carries `info` on every call, `includeInfo` is a no-op here:
```typescript theme={null}
agent.info?.variationCount; // how many variations the agent has
agent.info?.createdBy; // the profile that made it
```
`variationCount` is the quick way to spot an agent that cannot run yet: a published agent needs at least one variation, and a `0` on a draft is why it cannot publish.
## Paging and filtering
The usual list controls apply: `limit` (1 to 100), `cursor`, `prefix` (name starts-with), and `query` (free-text over name and description). A [`pagination`](/docs/guides/api-design#list-requests) block with a `nextCursor` comes back while more pages remain, and is absent on the last page.
```typescript theme={null}
const published = client.agents.list({ workspaceId, state: 'STATE_PUBLISHED', query: 'support', limit: 20 });
```

description: API for the Cadenya Agent Runtime platform.
version: '1.0'
servers:
- url: https://api.cadenya.com
description: Production server
security:
- bearerAuth: []
tags:
- name: AIProviderKeyService
- name: APIKeyService
description: |-
Issue, rotate, disable, and revoke a workspace's API keys. Every key
belongs to exactly one workspace; the system-managed global account key is
managed via GlobalAPIKeyService instead.
- name: AccountService
description: >-
Manage the authenticated account. Accounts are the top-level
organizational
unit and contain one or more workspaces.
- name: AgentScheduleService
description: >-
Manage recurring schedules attached to agents. Schedules trigger
objectives
on a cadence defined by AgentScheduleSpec.Schedule.
- name: AgentService
description: >-
Manage AI agents within a workspace. Agents define AI behavior and tool
access.
- name: AgentVariationService
description: >-
Manage variations of an agent and their tool, sub-agent, and memory layer
assignments.
- name: GlobalAPIKeyService
description: |-
Manage the account's system-provisioned global API key. The global key is
the only key that spans every workspace; it is created by the system and
cannot be deleted, so the surface is retrieve, rotate, and the
disable/enable kill switch.
- name: MemoryService
description: >-
Manage memory layers and their entries. Layers are named containers that
can
be composed into an objective's memory cascade; entries are the keyed values
within a layer. System-managed layers (e.g., episodic layers created by the
runtime) cannot be mutated through this API.
- name: ModelService
description: |-
Manage LLM models available to a workspace. Models represent provider and
family pairs (e.g., "anthropic/claude-sonnet-4.6"). Workspaces are seeded
with the supported models and you can enable or disable each one.
- name: ObjectiveEventStreamsService
- name: ObjectiveService
- name: ProfilesService
description: |-
Operations on profiles, the account-level principals (users, API keys,
system) that authenticate against the API.
- name: SearchService
- name: TenantService
description: >-
Read and erase tenants and the subjects under them. Tenants and subjects
are
created by assertion — on objective creation or widget session mint — never
directly, so this service has no create or update: it exists to enumerate what
assertions have produced, and to destroy it on request.
- name: ToolService
description: >-
Manage tool sets and the tools they contain. Tool sets group related
tools,
and tools define specific capabilities available to agents.
When a tool set is managed, only API key actors can modify its tools; human
(profile) actors cannot.
- name: UploadService
description: |-
Issue short-lived presigned URLs for direct client-to-object-storage
uploads. Created uploads can be referenced by id when creating or updating
resources that accept binary content (e.g., MemoryEntry).
- name: WidgetService
description: |-
Manage embeddable chat widgets. A widget binds an agent to a globally
unique hostname with a per-widget origin allowlist; browsers reach it with
session tokens minted via WidgetSessionService.
- name: WidgetSessionService
description: >-
Mint and manage widget sessions. Session creation is server-to-server
only:
the customer's backend authenticates its visitor, asserts tenant/subject
context, attaches any per-visitor secrets, and receives a short-lived
bearer token the browser uses against the widget host.
- name: WorkspaceAdminService
description: >-
Administer workspaces across the account: create and archive workspaces
and
manage their membership. These operations are account-scoped and require the
admin role (a token whose profile holds the WorkOS admin role); they live
under /v1/account/workspaces rather than the workspace-scoped /v1/workspaces
tree so an admin can manage any workspace in the account, including ones they
are not themselves a member of.
- name: WorkspaceSecretService
- name: WorkspaceService
description: |-
Manage workspaces within an account. Workspaces provide organizational
grouping and isolation for resources such as agents, tools, and API keys.
This is the workspace-scoped, end-user surface. Administrative operations
(create / archive workspaces, manage members) live in WorkspaceAdminService
under /v1/account/workspaces and require the admin role.

The `Status` type defines a logical error model that is suitable for
different programming environments, including REST APIs and RPC APIs. It
is used by [gRPC](https://github.com/grpc). Each `Status` message
contains three pieces of data: error code, error message, and error
details. You can find out more about this error model and how to work
with it in the [API Design
Guide](https://cloud.google.com/apis/design/errors).

SystemPromptDataSchema enforces the shape of system_prompt_data when
objectives are created. This is valuable when using liquid
formatting in agent
variation system prompt templates. The schema is also used when the agent is attached as a sub-agent, as it becomes the tool's input parameter schema.
If omitted, the sub-agent schema will be loaded with a simple "prompt" free text string as its schema.
outputDefinition:
type: object
additionalProperties: true
description: |-
Optional output definition for objectives created for this agent.
When provided, Cadenya will append a tool to that will be called by the LLM in use by the variant to extract information in the format provided here.
Use this option when you want structured data to be created by your objectives.
enableEpisodicMemory:
type: boolean
description: |-
Enable episodic memory for objectives created for this agent.
When true, objective creation requires an episodic_memory key and the
system finds or creates a memory layer for that (agent, key) pair, letting
the agent store and retrieve memories across objectives that share the key.
Memory is agent-level so all variations of the agent share the same layers.

type: integer
description: |-
How long episodic memories should be retained.
Each new objective slides the layer's expiry forward by this duration, and
stored entries expire this long after they are written.
If not set, episodic memories are retained indefinitely.
