- `endpointId` string, required — Endpoint identifier.
- `deploymentId` string, required — Deployment identifier.

## Request body

- DEAddAdapterRequest — Configuration for attaching a LoRA adapter to a deployment that has adapter loading enabled.
  - `adapterModelId` string, required — Adapter model identifier to attach.
  - `adapterRevisionId` string — Optional adapter revision to pin. If omitted, the latest revision is resolved at request time.
  - `force` boolean — Whether to evict the oldest adapter if the deployment is at adapter capacity.
