# Get Co Author Summary
> Gets aggregated co-author summary for the organization or a specific project.
`Unary` ยท [`Usage`](/docs/api-reference/generated/usage/overview)
Gets aggregated co-author summary for the organization or a specific project.
Use this method to:
* Measure AI-assisted commits and line changes
* Scope co-author insights to a project, user, or team
* Compare the requested date range against the previous period
### Example
```yaml theme={null}
dateRange:
startTime: "2024-01-01T00:00:00Z"
endTime: "2024-02-01T00:00:00Z"
projectId: "d2c94c27-3b76-4a42-b88c-95a85e392c68"
```
## Endpoint
```text theme={null}
POST /api/gitpod.v1.UsageService/GetCoAuthorSummary
```
Send a Bearer token as described in [Authentication](/docs/api-reference#authenticate-requests). If your organization uses a custom management-plane domain, replace `https://app.ona.com` with that domain.
## Request example
```bash cURL theme={null}
export ONA_HOST=https://app.ona.com
export ONA_API_KEY=
curl --request POST \
--url "$ONA_HOST/api/gitpod.v1.UsageService/GetCoAuthorSummary" \
--header "Authorization: Bearer $ONA_API_KEY" \
--header "Content-Type: application/json" \

"endTime": "2026-01-01T00:00:00Z",
"startTime": "2026-01-01T00:00:00Z"
}
}'
