Resources

The OpenAQ API uses a resource-based design. Each endpoint returns data specific to that resource. The OpenAQ Python SDK simplifies these calls by exposing resources directly through the client. Every SDK response supports reading data as a Python object, a dictionary, or a JSON string.

from openaq import OpenAQ

with OpenAQ(api_key="replace-with-valid-openaq-api-key") as client:
    response = client.instruments.get(instruments_id=2)

Caution

This example uses a placeholder API key `replace-me-with-a-valid-key` and will not work as-is. Replace this value with a valid OpenAQ API key.

from openaq import OpenAQ

with OpenAQ(api_key="replace-with-valid-openaq-api-key") as client:
    # client.instruments represents the Instruments resource
    response = client.instruments.get(instruments_id=2)

Caution

This example uses a placeholder API key `replace-me-with-a-valid-key` and will not work as-is. Replace this value with a valid OpenAQ API key.

The Resource Model

To make the SDK predictable and easy to navigate, every resource exposes a consistent interface. As you browse the individual resource pages, you will see the same design patterns repeated across all endpoints.

Common Methods

Most resources implement two primary methods for interacting with the underlying data:

• .get(): Used when you know the unique identifier for a specific asset (for example, a specific country or location ID). This targets a single record and requires a path argument.
• .list(): Used to browse, filter, or page through collections of records. This method accepts optional query arguments and returns all records matching your criteria.

SDK Resource Directory

You can access the various aspects of the OpenAQ dataset using the following core client properties:

Resource	Client Property	Primary Purpose
Locations	client.locations	Query physical monitoring stations to find coordinates, operating hardware, and baseline metrics.
Sensors	client.sensors	Query individual measuring units to check reporting intervals, physical locations, and data coverage stats.
Measurements	client.measurements	Query raw or aggregated air quality data by fixed intervals or custom time-based averages.
Licenses	client.licenses	Query data usage rules, including permissions for commercial use, attribution, and modification rights.
Manufacturers	client.manufacturers	Query companies that build monitoring hardware and list all of their equipment models.
Instruments	client.instruments	Query specific hardware details, device names, and whether equipment meets regulatory standards.
Parameters	client.parameters	Query tracked variables (gases, particulates, weather metrics) and pull recent global readings.
Providers	client.providers	Query organizations supplying data feeds and filter them by region or reporting timelines.
Owners	client.owners	Query the upstream entities or individuals that own and manage the physical monitoring hardware.
Countries	client.countries	Query countries with active monitoring stations to track coverage windows and country codes.
