Air Quality Monitor - India #for-flows

Number of APIs: 2

Get latest air quality metrics from data.gov.in by city.

Requirements

Get an API Key from data.gov.in.
Set the following environment variables:
- api-key: The API key you got from data.gov.in
- state: The name of a state in India, in title case, e.g., West Bengal.
- city: A city within that state, e.g., Kolkata.
Optional environment variables:
- airtableURL: An API URL for an Airtable Base where the max values of each pollutant is pushed.
- airtableKey: The API Key for your Airtable account.

Result

At the end of each run, a JSON array is saved in the environment variable called results. This variable value can be used in subsequent requests to push the data to some endpoint.

The structure of the JSON object is in the following format:

[
    "station": String,
    "<Pollutant ID>": {
        "min": Number,
        "max": Number,
        "avg": Number
    }
]

Each city can have multiple stations from where the pollution is monitored. There can be multiple pollutant information, depending on the stations. These include: PM2.5, PM10, NO2, OZONE, CO, SO2 and NH3.

Push to Airtable

You can configure this collection to push data to an Airtable. Here is an example of such a table in action.

To do that, set up an Airtable with the following columns:

Station
PM2.5
PM10
NO2
OZONE
CO
SO2
NH3
You can optionally add a column of type "Created time" to keep track of when the rows were inserted.

Once that is done, get the API endpoint for that table and add that in the airtableURL environment variable. You will also need your Airtable API Key, which needs to be put in the airtableKey environment variable.

To keep things single, this collection pushes only the max values of each pollutant. Feel free to hack on the structure in the Pre-request script of the Post to Airtable request.
