## Endpoint

```http
POST /admin/v1/workspace-accesses/{accessId}/api-keys
```

Operation ID: `createInferenceKey`

## Authentication

Send a Nexus Management Key as `Authorization: Bearer <management-key>`. This credential is control-plane only.

## Idempotency

This operation does not declare an `Idempotency-Key` requirement in the accepted OpenAPI contract.

## Request

| `accessId` | path     | Yes      | `string` | —           |

### application/json body

Type: `CreateInferenceKeyDto`

| Field              | Required | Type     | Description |

## Examples

### TypeScript Management SDK

`NexusAdminClient.createInferenceKey` uses `AdminOperationInput<"createInferenceKey">` and returns `Promise<AdminOperationOutput<"createInferenceKey">>`.

```ts
import { NexusAdminClient } from '@nexus/sdk-typescript';

const nexus = new NexusAdminClient({
  baseUrl: 'https://nexus.microvoid.io',
  managementKey: process.env.NEXUS_MANAGEMENT_KEY,
});

const result = await nexus.createInferenceKey({
  path: {
    accessId: '533c4e1e-2823-4349-86b9-d6f1a869a2ca',
  },
  body: {
    name: 'Production',
    expiresInSeconds: 1,
  },
});
```

### Fetch

```ts
const response = await fetch(
  'https://nexus.microvoid.io/admin/v1/workspace-accesses/533c4e1e-2823-4349-86b9-d6f1a869a2ca/api-keys',
  {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${process.env.NEXUS_MANAGEMENT_KEY}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      name: 'Production',
      expiresInSeconds: 1,
    }),
  },
);

if (!response.ok) throw new Error(`Nexus request failed: ${response.status}`);
```

### curl

```bash
curl --request POST \
  "https://nexus.microvoid.io/admin/v1/workspace-accesses/533c4e1e-2823-4349-86b9-d6f1a869a2ca/api-keys" \
  --header "Authorization: Bearer ${NEXUS_MANAGEMENT_KEY}" \
  --header "Content-Type: application/json" \
  --data "{\"name\":\"Production\",\"expiresInSeconds\":1}"
