# List Models

GET https://app.polytomic.com/api/models

Lists all models in the caller's organization.

Results are ordered by `updated_at` descending, with `id` used as a tiebreaker.
If more results are available, the response includes `pagination.next_page_token`.
Pass that token back unchanged to continue from the last item you received.

The token is opaque. Do not construct or edit it yourself.

The `limit` is capped at 50. Values above that cap are reduced to 50, and
non-positive values fall back to the same default.

## Authentication

- `Authorization` header (basic auth, required) — This is the Polytomic deployment key (on-premises only)
- `Authorization` header (bearer token, required) — This is the Polytomic API key

## Response

### 200

OK

- `data` (list of V2ModelResponse, optional, nullable)

## Errors

### 401 Unauthorized Error

Unauthorized

- `code` (integer, optional) — Application-specific error code.
- `context` (map from string to any, optional) — Application context.
- `error` (string, optional) — Error message.
- `status` (string, optional) — Status text.

### 404 Not Found Error

Not Found

- `key` (string, optional)
- `message` (string, optional)
- `metadata` (map from string to any, optional)
- `status` (integer, optional)

## Types

### V2ModelResponse

- `configuration` (map from string to any, optional)
- `connection_id` (string, optional)
- `created_at` (string, optional)
- `created_by` (OutputActor, optional)
- `enricher` (V2Enrichment, optional)
- `fields` (list of V2ModelField, optional)
- `id` (string, optional)
- `identifier` (string, optional)
- `labels` (list of LabelLabel, optional)
- `name` (string, optional)
- `organization_id` (string, optional)
- `policies` (list of string, optional)
- `relations` (list of V2Relation, optional)
- `tracking_columns` (list of string, optional)
- `type` (string, optional)
- `updated_at` (string, optional)
- `updated_by` (OutputActor, optional)
- `version` (integer, optional)

### OutputActor

- `id` (string, optional)
- `name` (string, optional)
- `type` (string, optional)

### V2Enrichment

- `configuration` (map from string to any, optional) — Similar to a model configuration, this configures the enricher. For example, if you wanted to use Apollo to enrich people, you would send `{"object": "people"}` as the configuration. Each enricher configuration can be found in the connection configuration docs.
- `connection_id` (string, optional)
- `enricher_id` (string, optional) — Must be provided to update an existing enrichment
- `fields` (list of V2ModelField, optional) — If not provided, all fields will be enabled.
- `mappings` (map from string to string, optional) — A map of parent model Source Name to child model Source Name. For example, if your model has a field called `work_email` and the enricher accepts a field called `email`, you'd send a map of `{"work_email":"email"}`. The set of required input mappings varies based on the configuration of the enrichment. You can use the `enrichment/{connection_id}/inputfields` API to discover available input field combinations for a given configuration.

### V2ModelField

- `created_at` (string, optional)
- `created_by` (OutputActor, optional)
- `description` (string, optional)
- `example` (any, optional)
- `id` (string, optional)
- `label` (string, optional)
- `name` (string, optional)
- `remote_type` (string, optional)
- `type` (string, optional)
- `unique` (boolean, optional)
- `updated_at` (string, optional)
- `user_added` (boolean, optional)

### LabelLabel

### V2Relation

- `from` (string, optional)
- `to` (V2RelationTo, optional)

### V2RelationTo

- `field` (string, optional)
- `model_id` (string, optional)
