# List vendors

GET https://api-gateway.merge.dev/v1/vendors

List execution vendors and the models they currently serve. Paginated the same way as /models: a page holds at most 500 vendors, and next_cursor walks the rest.

Reference: https://docs.merge.dev/merge-gateway/api-overview/vendors/list

## Authentication

- `Authorization` header (bearer token, required) — Your production key sent as a bearer token.

## Request

### Query parameters

- `zero_data_retention` (boolean, optional) — Filter vendors by zero data retention support.
- `cursor` (string, optional) — Pagination cursor. Pass the next_cursor returned by the previous page to fetch the vendors that follow it. Omit on the first request.
- `limit` (integer, optional, default: 50) — Vendors per page. Defaults to 50, minimum 1, maximum 500. A limit above 500 is rejected with 422; page through the rest with next_cursor rather than raising it.

## Response

### 200

Successful Response

- `data` (list of PublicVendor, required)
- `object` ("list", optional, default: list)
- `has_more` (boolean, optional, default: false) — True when more vendors remain beyond this page. Keep paging while this is true.
- `next_cursor` (string, optional, nullable) — Cursor to pass as ?cursor= to fetch the next page. Null on the last page.

## Errors

### 422 Unprocessable Entity Error

Validation Error

- `detail` (list of ValidationError, optional)

## Types

### PublicVendor

An execution host that Merge Gateway can route to (e.g. `openai`, `bedrock`, `azure`). Lists the model IDs the vendor can serve plus its ZDR and BYOK support.

- `vendor` (string, required)
- `name` (string, required)
- `models` (list of string, required)
- `supports_zdr` (boolean, required)
- `supports_byok` (boolean, required)
- `availability_status` (enum, required)
  - Allowed values: `active`, `degraded`, `unavailable`

### ValidationError

Single field-level validation error. `loc` is the JSON path to the offending field, `msg` is a human-readable explanation, and `type` is a stable machine-readable error code.

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

### ValidationErrorLocItems

### ValidationErrorCtx
