Authorizations

Authorization

string

header

required

User session JWT (Bearer ). Must be paired with the X-Team-ID request header on team-scoped endpoints so the server knows which team's resources to operate on.

Headers

X-Team-ID

string<uuid>

UUID of the team to scope the request to. Used by dual-auth endpoints (runtime + scoped management):

JWT callers MUST send it — a user may belong to multiple teams and the runtime cannot otherwise know which one to operate on. Missing header → 400.
Credential callers (sk-, dk-) can omit it because the team is derived from the credential row itself. Any value sent is ignored.

Example:

"019abc12-4567-7890-abcd-ef1234567891"

Path Parameters

workflowSlug

string

required

Workflow slug for runtime lookup. Use slug for the latest version or slug@version to reference an immutable workflow snapshot, e.g. text-to-image@2.

Maximum string length: 128

Pattern: ^[a-z0-9]+(?:-[a-z0-9]+)*(?:@[1-9][0-9]*)?$

Example:

"text-to-image@2"

Body

application/json

Request body to execute a workflow with optional parameter overrides.

Workflow run usage

Step 1 — Discover available parameters

Call GET /r/workflows/{workflowId} or GET /r/workflows/slug/{workflowSlug} to retrieve the workflow detail. To target a previous workflow version, use slug@version (for example, text-to-image@2). The parameters array contains ParameterDef entries that describe every user-configurable input. Each entry has:

Field	Purpose
`key`	The key you use in the request body below
`type`	`string` / `number` / `boolean` / `select` / `file`
`label`	Human-readable label for UI rendering
`description`	Optional description of what this parameter does
`required`	If `true`, you must provide a value
`default`	Value used when the key is omitted (optional params only)
`min` / `max`	Numeric bounds (only for `type: number`)
`options`	Allowed values list (only for `type: select`)
`accept`	Allowed MIME patterns (only for `type: file`, e.g. `image/*`)

Example parameters from a workflow detail response:

[
  {"key": "prompt", "node_id": "6", "field": "text", "type": "string",
   "label": "Positive Prompt", "required": true},
  {"key": "width",  "node_id": "5", "field": "width", "type": "number",
   "label": "Width", "min": 64, "max": 2048, "default": 512},
  {"key": "sampler", "node_id": "3", "field": "sampler_name", "type": "select",
   "label": "Sampler", "options": ["euler", "euler_ancestral", "dpmpp_2m"],
   "default": "euler"},
  {"key": "input_image", "node_id": "10", "field": "image", "type": "file",
   "label": "Input Image", "required": true, "accept": ["image/*"]}
]

Step 2 — Build the run request

Use the key values from the parameter definitions as keys in the parameters object:

POST /r/workflows/{workflowId}/run
{
  "parameters": {
    "prompt": "sunset over ocean",
    "width": 1024,
    "sampler": "dpmpp_2m"
  }
}

For type: file parameters, upload the file first, then pass the file_key:

POST /r/files/presign with {"file_name": "photo.png", "file_size": 1048576, "content_type": "image/png"}
Upload the file to the returned upload_url via HTTP PUT.
Pass the file_key as the parameter value:

{
  "parameters": {
    "input_image": "inputs/{team}/{uuid}/photo.png",
    "prompt": "enhance this photo"
  }
}

Step 3 — Validation rules

Unknown keys → 400 Bad Request (only keys from ParameterDef are accepted).
Missing required keys → 400 Bad Request.
Type mismatch → 400 Bad Request (e.g. string for a number parameter).
Out of range → 400 Bad Request (number outside min/max bounds).
Invalid select value → 400 Bad Request (value not in the options list).
File not uploaded → 400 Bad Request (file_key not found in S3).
File wrong team → 400 Bad Request (file_key must belong to the team).
File type rejected → 400 Bad Request (file MIME doesn't match accept pattern).
Omitted optional keys → the workflow's default value is used automatically.
Empty body {} → valid if no parameters are required (all have defaults).
Workflow with no parameters → send {} or omit parameters entirely.

Step 4 — Poll for results

The response contains a task_id. Poll status:

GET /r/tasks/{taskId}

When task_status is completed, fetch the output:

GET /r/tasks/{taskId}/result

parameters

object

Key-value map of parameter overrides. Keys must match the key field of a ParameterDef entry defined in the workflow's parameters array.

For type: file parameters, the value must be a file_key string obtained from POST /r/files/presign. Upload the file first, then pass the key here.

Retrieve available keys by calling GET /r/workflows/{workflowId} or GET /r/workflows/slug/{workflowSlug} and inspecting the parameters array in the response. Use workflowSlug@version to discover parameters for a previous workflow version.

Maximum 100 parameter keys per request.

Example:

{
  "prompt": "sunset over ocean",
  "width": 1024,
  "input_image": "inputs/019abc12-3456/550e8400-e29b/photo.png"
}

dispatch_target

enum<string>

Where to execute this task:

agent (default): Execute on a local BYOC agent.
comfy_cloud: Execute on ComfyUI Cloud (requires configured API key).

If omitted, the workflow's default_dispatch_target is used, falling back to agent.

Available options:

agent,

comfy_cloud

Example:

"agent"

target_pool

enum<string>

Dispatch pool for this task. Only meaningful when dispatch_target=agent.

team (default): route to an agent in the same team — the P2.1 behaviour.
community: route to any opted-in agent across teams via the Cyberun community pool. Submitting team does not need to opt in to consume; the serving agent does.

If omitted, defaults to team.

Available options:

team,

community

Example:

"team"

submitter_region

string

Submitter's declared geographic / network locality, used by the P3.1 scoring engine to favour region-matching agents when multiple candidates are eligible. Opaque user-supplied string (e.g. us-east, eu-central, ap-southeast); normalised server-side to lowercase + trimmed. Empty / omitted → scorer treats as unknown (neutral 0.5 region factor; no agent is disqualified). Has no effect on dispatch_target=comfy_cloud.

Maximum string length: 64

Example:

"us-east"

tool_type

enum<string>

Tool runtime used by this workflow:

comfyui: ComfyUI API workflow JSON (default, backward compatible).
nerfstudio: Nerfstudio 3DGS pipeline spec.

Available options:

comfyui,

nerfstudio

Example:

"comfyui"

Response

Task submitted

task_id

string<uuid>

required

ID of the created task. Use this to poll task status and results.

Example:

"019abc12-9012-7890-abcd-ef1234567896"
