SCM model registry

The model registry exposes a catalogue of peer-reviewed structural causal models (SCMs) across scientific domains. These models encode causal structure — nodes, edges, and constraints — that power intervention validation, counterfactual tracing, and integrity checking throughout the Wu-Weism platform.

Both endpoints in this group are public. You do not need an Authorization header to read the model registry.

List all SCM models

GET /api/scm/models

Returns all publicly available SCMs in the registry.

Response fields

boolean

required

true when the request succeeds.

object[]

required

Array of model summary objects.

Show model object properties

string

Unique identifier for the model. Use this key when calling other SCM endpoints.

string

Semantic version of the model (e.g., "1.0.0").

string

Scientific domain the model covers. See domain values below.

string

Human-readable summary of the model’s scope and intended use.

string[]

Variable names modelled as nodes in the causal graph.

object[]

Directed causal edges between nodes, each with from and to properties.

object

Structural constraints and assumptions encoded in the model.
