# Plot the All Share Index

> Fetch NGX All Share Index history and render it as a price chart.

The ASI (All Share Index) is the NGX benchmark index. This example fetches the last 90 days of daily values in chart-friendly `[timestamp, value]` format, ready to drop into any charting library like Chart.js, Recharts, or Highcharts.

**Endpoint:** `GET /indices/ASI/chart` (Starter plan)

## Fetch 90-day ASI history

<CodeGroup>
  ```bash curl theme={null}
  curl "https://api.ngnmarket.com/v1/indices/ASI/chart?period=90d&format=chart" \
    -H "Authorization: Bearer ngm_live_YOUR_KEY"
  ```

  ```javascript JavaScript theme={null}
  const res = await fetch(
    'https://api.ngnmarket.com/v1/indices/ASI/chart?period=90d&format=chart',
    { headers: { Authorization: 'Bearer ngm_live_YOUR_KEY' } }
  );
  const { data } = await res.json();

  // data.data is an array of [timestamp, value] pairs
  const chartPoints = data.data;
  // e.g. [[1744848000000, 105432.18], [1744761600000, 104555.74], ...]
  ```

  ```python Python theme={null}
  import requests

  res = requests.get(
      'https://api.ngnmarket.com/v1/indices/ASI/chart',
      params={'period': '90d', 'format': 'chart'},
      headers={'Authorization': 'Bearer ngm_live_YOUR_KEY'},
  )
  chart_points = res.json()['data']['data']
  # [[1744848000000, 105432.18], [1744761600000, 104555.74], ...]
  ```
</CodeGroup>

## Sample response

```json theme={null}

  }
}
```

## Use a custom date range

Swap `period` for `from` and `to` if you need a specific window:

```bash curl theme={null}
curl "https://api.ngnmarket.com/v1/indices/ASI/chart?from=2026-01-01&to=2026-03-31&format=chart" \
  -H "Authorization: Bearer ngm_live_YOUR_KEY"
```

## Need full OHLCV detail?

Drop `format=chart` and use `format=detailed` instead. Each point then includes `date`, `value`, `change`, and `change_percent` fields individually.
