# List Catalog Provider Models

GET https://api.onepin.ai/api/v1/providers/{provider}/models

List the models available to your account for a given provider.

Returns each model's display name, content type, live `voice_count` (the
number of platform voices catalogued under that model that can produce an
officially supported locale on it — the same population the model's `voices`
link returns), a `beta` badge flag, and
a `controls` map describing the canonical provider-agnostic parameters supported
by the model (e.g. speed, stability). Also includes `config_schema` for
back-compat — new integrations should prefer `controls` as the authoritative
parameter description. Each item includes a HATEOAS `voices` link to the paginated
voice list for that model.

Models staff have restricted to internal accounts or paying customers are omitted
unless your account qualifies. Returns 404 if the provider is not recognized or
has no models available to your account.

## Authentication

- `Authorization` header (bearer token, required) — Clerk JWT token
- `Authorization` header (bearer token, required) — Onepin live API key (`op_live_...`). Test and public keys are reserved in Phase 1.

## Servers

- `https://api.onepin.ai` (prod, default)
- `https://dev-api.onepin.ai` (dev)

## Request

### Path parameters

- `provider` (string, required)

### Headers

- `X-Workspace-Id` (string, optional, nullable)

## Response

### 200

Successful Response

- `data` (list of CatalogModelOut, required)
- `meta` (Meta, required)
- `pagination` (PaginationMeta, required)

## Errors

### 404 Not Found Error

Provider not found

- `error` (ApiErrorBody, required)
- `meta` (Meta, required)

### 422 Unprocessable Entity Error

Validation Error

- `detail` (list of ValidationError, optional)

## Types

### CatalogModelOut

Catalog model entry — lean, customer-safe. ``config_schema`` is the per-model NATIVE TTS config JSON-schema. POD-670: ``config_schema`` is now DEPRECATED as the FE slider source — read ``controls`` instead (the provider-agnostic canonical supported-set). ``config_schema`` is kept populated for back-compat until the FE migrates (POD-718). ``voice_count`` is the number of active platform voices catalogued under this ``(provider, model)``.

- `model` (string, required)
- `display_name` (string, required)
- `voice_count` (integer, required)
- `content_type` (string, optional, nullable)
- `config_schema` (map from string to any, optional)
- `controls` (map from string to any, optional)
- `beta` (boolean, optional, default: false)
- `links` (map from string to CatalogLink, optional)

### Meta

- `request_id` (string, required)
- `timestamp` (datetime, required)

### PaginationMeta

- `limit` (integer, required)
- `next` (string, optional, nullable)
- `prev` (string, optional, nullable)

### ApiErrorBody

- `code` (string, required)
- `message` (string, required)
- `details` (list of ApiErrorDetail, optional, default: [])

### ValidationError

- `loc` (list of ValidationErrorLocItems, required)
- `msg` (string, required)
- `type` (string, required)
- `input` (any, optional)
- `ctx` (ValidationErrorCtx, optional)

### CatalogLink

HATEOAS link to a nested catalog resource (HAL-FORMS-flavored). The server emits a concrete, ready-to-call ``href`` (path segments already filled in and URL-encoded) so the FE never constructs catalog URLs itself.

- `href` (string, required)
- `method` (string, optional, default: GET)

### ApiErrorDetail

- `field` (string, required)
- `message` (string, required)
- `line_numbers` (list of integer, optional, nullable)
- `min_chars` (integer, optional, nullable)

### ValidationErrorLocItems

### ValidationErrorCtx
