Pricing overview

AQICN provides access to real-time, historical, and forecast air quality data through a tiered pricing structure, designed to accommodate various usage levels from individual developers to commercial entities. The pricing model includes a free tier for low-volume use and subscription-based paid plans that scale with the number of API calls per day. This structure allows users to select a plan that aligns with their application's data requirements and budget, eliminating unexpected overage charges by providing clear daily call limits for each tier AQICN API pricing page.

The service focuses on delivering data points related to the Air Quality Index (AQI) and specific pollutant concentrations (e.g., PM2.5, Ozone), which necessitates a robust infrastructure for data collection and distribution. The cost reflects the maintenance of a global network of air quality monitoring stations and data aggregation processes. While the free tier supports basic exploration and small-scale projects, commercial or high-traffic applications typically require a paid subscription to ensure consistent access and sufficient call allowances.

Free tier and limits

The AQICN API offers a free tier that provides up to 500 API calls per day. This tier is an accessible starting point for developers exploring air quality data, building non-commercial prototypes, or integrating the API into personal projects. The free tier includes access to real-time air quality index data for various locations globally, allowing users to retrieve current conditions and basic pollutant information AQICN API documentation.

Key aspects and limitations of the free tier include:

  • Daily Call Limit: 500 API calls within a 24-hour period. Exceeding this limit will result in temporary API key suspension until the next 24-hour cycle begins.
  • Data Access: Primarily provides access to real-time air quality data. Access to historical data or forecast data might be restricted or have tighter limits compared to paid plans.
  • Support: Community-level support is typically available, with priority support reserved for paid subscribers.
  • Commercial Use: The free tier is explicitly intended for non-commercial and personal use. Commercial applications, even those with low traffic, are generally expected to use a paid plan.

Developers can monitor their API usage through the AQICN user dashboard, which provides insights into daily call consumption and remaining quota. This transparency assists in managing usage to stay within the free tier limits or to determine when an upgrade to a paid plan becomes necessary.

Real-world cost examples

Understanding the practical costs of using the AQICN API involves considering typical application scenarios and their corresponding API call requirements.

Example 1: Personal Weather Dashboard

A developer creates a personal web dashboard that displays real-time air quality for their home city and two other frequently visited locations. The dashboard refreshes data every 15 minutes.

  • API calls per refresh: 3 (one for each location).
  • Refreshes per day: 24 hours * 4 refreshes/hour = 96 refreshes.
  • Total daily API calls: 3 calls/refresh * 96 refreshes/day = 288 API calls.

Cost: This scenario falls well within the 500 daily API call limit of the Free Tier. The cost would be $0 per month.

Example 2: Small Mobile Application

A small mobile application allows users to check air quality for their current location. The app has approximately 50 active users, and each user checks their location's air quality an average of 3 times per day.

  • API calls per user per day: 3 calls.
  • Total daily API calls: 50 users * 3 calls/user = 150 API calls.

Cost: Even with 50 active users, this usage remains within the 500 daily API call limit of the Free Tier. The cost would be $0 per month, assuming the application is non-commercial or falls under approved free-tier usage guidelines.

Example 3: Local News Website Widget

A local news website integrates an air quality widget displaying data for 5 key locations in their coverage area. The widget updates every 5 minutes to ensure timely information for its readership.

  • API calls per refresh: 5 (one for each location).
  • Refreshes per day: 24 hours * 12 refreshes/hour = 288 refreshes.
  • Total daily API calls: 5 calls/refresh * 288 refreshes/day = 1,440 API calls.

Cost: This scenario exceeds the Free Tier's 500 daily calls. It would require the Hobbyist Plan, which provides 5,000 daily API calls for $20 per month AQICN API pricing.

Example 4: Environmental Monitoring Platform

An environmental monitoring platform tracks air quality across 50 cities globally, updating data once every hour for each location. The platform also fetches historical data for each city once a day for trend analysis, equating to an additional call per city.

  • Real-time API calls per day: 50 locations * 24 updates/day = 1,200 calls.
  • Historical data API calls per day: 50 locations * 1 call/day = 50 calls.
  • Total daily API calls: 1,200 + 50 = 1,250 API calls.

Cost: This platform's usage of 1,250 daily calls exceeds the Free Tier. It would fit comfortably within the Hobbyist Plan at $20 per month, providing up to 5,000 daily API calls AQICN pricing tiers.

Example 5: Enterprise Logistics Application

A large logistics company integrates air quality data into its route optimization software. It queries air quality for 500 different locations every 30 minutes during a 12-hour operational window each day.

  • Operational window refreshes: 12 hours * 2 refreshes/hour = 24 refreshes.
  • API calls per refresh: 500 locations.
  • Total daily API calls: 500 calls/refresh * 24 refreshes/day = 12,000 API calls.

Cost: This scenario significantly exceeds the Hobbyist plan. It would require the Developer Plan, which offers 20,000 daily API calls for $80 per month AQICN API plan details.

How the pricing compares

When evaluating AQICN's pricing, it's beneficial to compare it against alternative air quality and general weather data providers. The competitive landscape for environmental data APIs includes services like OpenWeatherMap, Tomorrow.io, and BreezoMeter, each with distinct pricing models and feature sets.

OpenWeatherMap

OpenWeatherMap offers a comprehensive suite of weather and environmental APIs, including air quality data. Their pricing model is typically freemium, with a substantial free tier (e.g., 1,000,000 calls/month for certain APIs) and paid plans based on calls per minute or calls per month. OpenWeatherMap's free tier often provides a higher volume of API calls compared to AQICN's 500 daily calls, making it potentially more attractive for developers needing higher initial volume without immediate cost. However, OpenWeatherMap's air quality data might be one of many features, whereas AQICN specializes primarily in air quality. For instance, the OpenWeatherMap Air Pollution API offers 1,000 calls per day on its free tier, which can be combined with other free tier weather data.

Tomorrow.io

Tomorrow.io (formerly ClimaCell) provides a weather and environmental intelligence platform, focusing on hyper-local, real-time data. Their pricing structure is generally geared towards commercial and enterprise users, often involving custom quotes or higher starting prices compared to AQICN's entry-level plans. While Tomorrow.io offers advanced features like impact forecasting and highly granular data, its cost point typically targets businesses with more extensive needs and budgets. The Tomorrow.io Weather API emphasizes high-resolution data, which often correlates with premium pricing.

BreezoMeter

BreezoMeter specializes in highly accurate, hyper-local, and real-time air quality and pollen data. Similar to Tomorrow.io, BreezoMeter's pricing is often tailored for commercial applications and enterprises, with a focus on specific geographic coverage and advanced data insights. They typically do not publicize detailed tiered pricing on their website, implying a more custom-solution approach. While they offer a free trial, their paid plans are generally positioned at a higher price point than AQICN, reflecting their focus on precision and commercial-grade data solutions BreezoMeter Air Quality API.

Overall Comparison

  • Free Tier Volume: OpenWeatherMap often provides a more generous free tier in terms of raw call volume for its air pollution API, which might be a deciding factor for very high-volume, non-commercial projects. AQICN's 500 daily calls are suitable for many personal projects but modest for scaled applications.
  • Specialization: AQICN's core focus on air quality data makes it a direct and often simpler choice for applications solely requiring this information. Alternatives like OpenWeatherMap offer broader environmental data, while Tomorrow.io and BreezoMeter provide more refined, hyper-local, and often more expensive solutions.
