# Close a quarter

> Mark a quarter complete and generate the quarter-close artifact.

Mark a quarter complete and generate the quarter-close artifact. Locks the period: subsequent score changes don't retroactively change the close artifact. Used at the end of a planning cycle.

```bash theme={null}
curl -X POST https://app.dacard.ai/api/quarter-close \
  -H "Authorization: Bearer $DACARD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "productId": "prod_abc",
    "period": "2026-Q1"
  }'
```

| Property | Value |
| - | - |
| **Auth** | Required |
| **Required scope** | Caller must own the product |
| **Cost** | 10 credits |
| **Idempotent** | Yes (second call returns the existing artifact) |

## Body

| Field | Type | Required | Notes |
| - | - | - | - |
| `productId` | string | yes | Product the quarter belongs to. |
| `period` | string | yes | Format: `YYYY-Q[1-4]`. |

## Reading the artifact

```bash theme={null}
curl -X GET "https://app.dacard.ai/api/quarter-close?productId=prod_abc&period=2026-Q1" \
  -H "Authorization: Bearer $DACARD_API_KEY"
```

GET returns the existing artifact for an already-closed period, or 404 if the quarter isn't closed yet.
