# DOE APIMS Air Quality (Hourly API)

## Status

**Status:** Browser dependent

**Freshness:** 0 days

Browser check succeeded

## Last checked

2026-09-06 at 20:36:28 UTC.

## File size

The health snapshot did not report a file size.

## Coverage

The view covers 68 Malaysian air-quality monitoring stations. It reports the
Air Pollutant Index (API) derived from pollutant readings for PM2.5, PM10, SO2,
NO2, O3, and CO.

## Schema

| Field | Type | Description |
| --- | --- | --- |
| `NO` | integer | Row number. |
| `STATE` | string | Malaysian state. |
| `LOCATION` | string | Monitoring-station location. |
| `hr_22` through `hr_13` | integer or null | Sixteen hourly API readings, ordered 22:00, 23:00, then 00:00 through 13:00. |

## Known quirks

- The table is JavaScript-rendered and collection requires Camofox.
- A `**` suffix means two or more pollutant parameters share the same dominant
  API index; normalized samples omit this display suffix.
- The legacy `apims.doe.gov.my` host returns 403 anti-bot responses. Use the
  current `eqms.doe.gov.my/APIMS/main` view.

## Breaking changes

None observed.

## Sample

- [samples/doe_apims.csv](samples/doe_apims.csv)
- [samples/doe_apims.json](samples/doe_apims.json)

## Reproducibility

Open `https://eqms.doe.gov.my/APIMS/main` in Camofox, wait 10 seconds for the
table to render, capture the accessibility snapshot, and close the tab.
