Authorizations

​
Authorization
string
header
required

API key passed as a Bearer token. Keys are scoped to one organisation and a set of permitted sites. Two keys per scope (primary + secondary) are issued to support zero-downtime rotation.

Authorization: Bearer <api-key>

Path Parameters

​
id
string
required

Cula-assigned resource ID in TypeID format (e.g. stp_01kqzcjrpxf27tge33jwvjhkff). Alternatively, pass your external ID prefixed with ext- (e.g. ext-MY-STEP-001). The ext- prefix is unambiguous because TypeIDs use _ separators and never start with ext-.

​
version_id
string
required

Config version ID.

Response

Config version detail.

A published version of a material processing config with inline data point configs, input container config, and output container config.

​
id
string
required

Config version ID.

Example:

"scv_01kqzcjrpyf27tgefy70hchba7"

​
config_id
string
required

Parent config ID.

Example:

"stc_01kqzcjrpyf27tgeevggzctpyk"

​
name
string
required

Human-readable name of this config version.

Example:

"Biomass Processing"

​
published_at
string<date-time>
required

When this version was published.

Example:

"2026-01-15T08:00:00Z"

​
data_point_configs
object[]
required

Step-level data point configs. Use these id values as config_id in the top-level data_points array when creating a step execution.

​
input_config
object
required

Input container config. Describes the data points expected on each input container in input[].data_points.

​
output_config
object
required

Output container config. Describes the data points expected on each output container in output[].data_points.

​
next_version_id
string | null

ID of the next version in the chain. Null if this is the active (latest published) version.

Example:

null

​
schema
object

JSON Schema (draft 2020-12) describing the expected request body shape for creating a runtime resource with this config version. The schema encodes which data points are required at each nesting level (step-level, input container-level, output container-level). Partners can use this for client-side validation before sending requests. See Request body schema for details on how to use this field.

Example:
{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "type": "object",
  "required": ["config_id", "site"],
  "properties": {
