POST/v1/memory_layers

Creates a new memory layer in the workspace

ParametersExpand Collapse

--metadata: object { name, externalId, labels }

CreateResourceMetadata contains the user-provided fields for creating a workspace-scoped resource. Read-only fields (id, account_id, workspace_id, profile_id, created_at) are excluded since they are set by the server.

--spec: object { type, description, expiresAt, systemManaged }

ReturnsExpand Collapse

memory_layer: object { metadata, spec, info }

MemoryLayer is a named container of memory entries that can be composed into an objective's memory stack. Layers are workspace-scoped resources. The layer type controls how its entries participate in the agent loop — see MemoryLayerType for details.

Memory stacks are LIFO: when an objective resolves a key, layers are walked from the top of the stack downward, and the first matching entry wins.

metadata: object { id, accountId, createdAt, 5 more }

Standard metadata for persistent, named resources (e.g., agents, tools, prompts)

id: string

Unique identifier for the resource (prefixed ULID, e.g., "agent_01HXK...")

accountId: string

Account this resource belongs to for multi-tenant isolation (prefixed ULID)

createdAt: string

Timestamp when this resource was created

Human-readable name for the resource (e.g., "Customer Support Agent", "Email Tool") Required for resources that users interact with directly

profileId: string

ID of the actor (user or service account) that created this resource

workspaceId: string

Workspace this resource belongs to for organizational grouping (prefixed ULID)

externalId: optional string

External ID for the resource (e.g., a workflow ID from an external system)

labels: optional map[string]

Arbitrary key-value pairs for categorization and filtering Examples: {"environment": "production", "team": "platform", "version": "v2"}

spec: object { type, description, expiresAt, systemManaged }

type: "MEMORY_LAYER_TYPE_UNSPECIFIED" or "MEMORY_LAYER_TYPE_EPISODIC" or "MEMORY_LAYER_TYPE_SKILLS"

"MEMORY_LAYER_TYPE_UNSPECIFIED"

"MEMORY_LAYER_TYPE_EPISODIC"

"MEMORY_LAYER_TYPE_SKILLS"

description: optional string

Human-readable description of the layer's purpose. Encouraged for user-created layers; system-managed layers may have a generated description.

expiresAt: optional string

For layers with a finite lifetime (e.g., episodic), the time at which the layer becomes eligible for cleanup. Set by the system; unset for persistent layers.

systemManaged: optional boolean

Server-set. True for layers managed by the system (e.g., episodic layers created automatically when an objective uses an episodic_key). System-managed layers cannot be assigned to objective stacks via the API and cannot be mutated by clients — their lifecycle is controlled entirely by the runtime.

info: optional object { createdBy, entryCount, lastUsedAt }

createdBy: optional object { metadata, spec }

Profile represents a human user at the account level. Profiles are account-scoped resources that can be associated with multiple workspaces through the Actor model. Authentication for profiles is handled via SSO/OAuth (WorkOS).

metadata: object { id, accountId, name, 3 more }

AccountResourceMetadata is used to represent a resource that is associated to an account but not to a workspace.

id: string

Unique identifier for the resource (prefixed ULID, e.g., "apikey_01HXK...")

accountId: string

Account this resource belongs to for multi-tenant isolation (prefixed ULID)

Human-readable name for the resource (e.g., "Customer Support Agent", "Email Tool") Required for resources that users interact with directly

profileId: string

externalId: optional string

External ID for the resource (e.g., a workflow ID from an external system)

labels: optional map[string]

Arbitrary key-value pairs for categorization and filtering Examples: {"environment": "production", "team": "platform", "version": "v2"}

spec: object { type, email, name }

ProfileSpec contains the profile-specific fields

type: "PROFILE_TYPE_USER" or "PROFILE_TYPE_API_KEY" or "PROFILE_TYPE_SYSTEM"

Type is the type of profile. User's are humans, API keys are computers. You know the deal.

"PROFILE_TYPE_USER"

"PROFILE_TYPE_API_KEY"

"PROFILE_TYPE_SYSTEM"

email: optional string

Email address of the user (required, unique per account)

Display name for the user (e.g., "Bobby Tables")

entryCount: optional number

Number of entries currently in this layer.

lastUsedAt: optional string

Timestamp of the most recent objective that resolved against this layer. Useful for surfacing unused layers in the dashboard.
