Create an upload

POST/v1/uploads

Issues a short-lived presigned URL for direct upload to object storage. The returned id is used to reference the upload from resources that accept binary content.

Body ParametersJSONExpand Collapse

metadata: CreateResourceMetadata { 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.

Human-readable name for the resource (e.g., "Customer Support Agent", "Email Tool")

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: UploadSpec { contentType, filename, sizeBytes }

contentType: string

MIME type the client will send. Baked into the presigned URL's signature — the PUT must match exactly or object storage will reject it.

filename: string

Client-supplied filename. Used for audit and display only; does not control the object's storage path.

sizeBytes: string

Expected size of the upload in bytes. Baked into the presigned URL as a Content-Length constraint.

ReturnsExpand Collapse

Upload = object { info, metadata, spec }

Upload is a workspace-scoped handle representing a single file upload flow. Clients call CreateUpload to receive a short-lived presigned URL, PUT the file directly to object storage, then reference the upload by id when creating or updating resources that accept binary content.

Uploads are one-shot: once consumed by a creating or updating resource, the upload transitions to UPLOAD_STATUS_CONSUMED and cannot be reused. Unused uploads expire and are garbage-collected by the runtime.

info: UploadInfo { createdBy, status, uploadUrl, uploadUrlExpiresAt }

createdBy: optional Profile { 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: AccountResourceMetadata { 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: ProfileSpec { 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.

formatenum

One of the following:

"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")

status: optional "UPLOAD_STATUS_UNSPECIFIED" or "UPLOAD_STATUS_PENDING" or "UPLOAD_STATUS_COMPLETE" or 2 more

Lifecycle state. Transitions PENDING → COMPLETE (storage confirms the object exists) → CONSUMED (a resource referenced this upload), or → EXPIRED (URL elapsed without a PUT).

formatenum

One of the following:

"UPLOAD_STATUS_UNSPECIFIED"

"UPLOAD_STATUS_PENDING"

"UPLOAD_STATUS_COMPLETE"

"UPLOAD_STATUS_CONSUMED"

"UPLOAD_STATUS_EXPIRED"

uploadUrl: optional string

Presigned PUT URL. Short-lived. The client must PUT with the exact Content-Type declared in the spec, and the body length must match size_bytes.

uploadUrlExpiresAt: optional string

Absolute time at which upload_url stops working.

formatdate-time

metadata: ResourceMetadata { 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

formatdate-time

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: UploadSpec { contentType, filename, sizeBytes }

contentType: string

MIME type the client will send. Baked into the presigned URL's signature — the PUT must match exactly or object storage will reject it.

filename: string

Client-supplied filename. Used for audit and display only; does not control the object's storage path.

sizeBytes: string

Expected size of the upload in bytes. Baked into the presigned URL as a Content-Length constraint.
