# Get Catalog Provider

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

Get a single speech synthesis provider by its canonical identifier.

Returns the same shape as an item in `GET /providers` — display name, model
count, `beta`, and a HATEOAS `models` link — but scoped to a single provider.
Returns 404 if the provider identifier is not recognized or is not available to
your account. The canonical identifier is the lowercase slug returned in the
`provider` field of the list response.

## 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` (CatalogProviderOut, required) — Catalog provider entry — lean, customer-safe. Sourced from the in-memory ``ProviderRegistry`` (TTS / ``operator`` kind). Cost, credentials, base_url, and enabled flags are excluded by construction.
- `meta` (Meta, 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

### CatalogProviderOut

Catalog provider entry — lean, customer-safe. Sourced from the in-memory ``ProviderRegistry`` (TTS / ``operator`` kind). Cost, credentials, base_url, and enabled flags are excluded by construction.

- `provider` (string, required)
- `display_name` (string, required)
- `kind` (string, required)
- `model_count` (integer, required)
- `beta` (boolean, optional, default: false)
- `links` (map from string to CatalogLink, optional)

### Meta

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

### 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
