Mock sample for your project: OpenAQ API

Instantly access empirical models of atmospheric density and composition that are recommended by the Committee on Space Research (COSPAR) for satellite drag calculations.
API requests must contain a key "API-Key" in the header (see code samples). Obtain a key from here.

Each API part has its own documentation. Jump to the desired API part and learn about the API through the given examples and tutorials.
In addition, for each API there are specific sample requests that you can send via Insomnia or Postman to see what the requests and responses look like.
Insomnia
To explore our APIs with Insomnia, follow these steps:
Open Insomnia and Import our workspace.
Specify your API key in your workspace: Manage Environments -> "api_key": your API key
Start exploring

Postman
To explore our APIs with Postman, follow these steps:
Import our request collections as well as our environment file.
Specify your API key in your environment: "api_key": your API key

API Client Libraries
To speed up development and make coding easier, we offer the following client libraries:
JavaScript client - try the live examples
Others like C#, Ruby, PHP, Python, ... automatically created for the Route Optimization API
Bandwidth reduction
If you create your own client, make sure it supports http/2 and gzipped responses for best speed.
If you use the Matrix, the Route Optimization API or the Cluster API and want to solve large problems, we recommend you to reduce bandwidth
by compressing your POST request
and specifying the header as follows: Content-Encoding: gzip. This will also avoid the HTTP 413 error "Request Entity Too Large".

Map Data and Routing Profiles
Currently, our main data source is OpenStreetMap. We also integrated other network data providers.
This chapter gives an overview about the options you have.
OpenStreetMap
Geographical Coverage
OpenStreetMap covers the whole world. If you want to see for yourself if we can provide data suitable for your region,
please visit GraphHopper Maps.
You can edit and modify OpenStreetMap data if you find that important information is missing, e.g. a weight limit for a bridge.
Here is a beginner's guide that shows how to add data. If you have edited data, we usually consider your data after 1 week at the latest.
Supported Vehicle Profiles
The Routing, Matrix and Route Optimization APIs support the following vehicle profiles:
Name | Description | Restrictions | Icon
-----------|:----------------------|:--------------------------|:---------------------------------------------------------
car | Car mode | car access | car image
small_truck| Small truck like a Mercedes Sprinter, Ford Transit or Iveco Daily | height=2.7m, width=2+0.4m, length=5.5m, weight=2080+1400 kg | small truck image
truck | Truck like a MAN or Mercedes-Benz Actros | height=3.7m, width=2.6+0.5m, length=12m, weight=13000 + 13000 kg, hgv=yes, 3 Axes | truck image
scooter | Moped mode | Fast inner city, often used for food delivery, is able to ignore certain bollards, maximum speed of roughly 50km/h | scooter image
foot | Pedestrian or walking without dangerous SAC-scales | foot access | foot image
hike | Pedestrian or walking with priority for more beautiful hiking tours and potentially a bit longer than foot. Walking duration is influenced by elevation differences. | foot access | hike image
bike | Trekking bike avoiding hills | bike access | bike image
mtb | Mountainbike | bike access | Mountainbike image
racingbike| Bike preferring roads | bike access | racingbike image
Please note:
all motor vehicles (car, smalltruck, truck and scooter) support turn restrictions via turncosts=true
the free package supports only the vehicle profiles car, bike or foot
up to 2 different vehicle profiles can be used in a single optimization request. The number of vehicles is unaffected and depends on your subscription.
we offer custom vehicle profiles with different properties, different speed profiles or different access options. To find out more about custom profiles, please contact us.
a sophisticated motorcycle profile is available up on request. It is powered by the Kurviger Routing API and favors curves and slopes while avoiding cities and highways.
TomTom
If you want to include traffic, you can purchase the TomTom Add-on.
This Add-on only uses TomTom's road network and historical traffic information.
Live traffic is not yet considered. If you are interested to learn how we consider traffic information, we recommend that you read this article.
Please note the following:
Currently we only offer this for our Route Optimization API.
In addition to our terms, you need to accept TomTom's End User License Aggreement.
We do not use TomTom's web services. We only use their data with our software.
