# Get All OES Results

> Retrieve all OES spectra for a data entry

Returns every processed OES result associated with a data entry. Use this for multi-spectrum captures (for example, NetCDF files that hold several spectra), where `GET /oes/{data_id}` returns only the latest result.

<ParamField path="data_id" type="string" required>
  The data entry UUID for the OES measurement
</ParamField>

<ParamField query="limit" type="integer" default="100">
  Maximum number of results to return (1–1000)
</ParamField>

<ParamField query="offset" type="integer" default="0">
  Number of results to skip for pagination
</ParamField>

## Response

Returns an array of OES result objects, ordered oldest to newest. Each object has the same shape as the [Get OES Data](/api-reference/oes/get) response.

<RequestExample>
  ```python Python theme={null}
  import requests

  response = requests.get(
      "https://api.atomscale.ai/oes/d290f1ee-6c54-4b01-90e6-d701748f0851/all",
      headers={"X-API-KEY": "YOUR_API_KEY"},
      params={"limit": 100, "offset": 0}
  )
  oes_results = response.json()
  ```
