Arlula API Documentation
Overview
The Arlula infrastructure is broken down into a few main sections, each relating to distinct actions including accessing, purchasing, managing, and utilising satellite imagery data from archival and tasking sources.
This documentation serves as a comprehensive resource to best understand the platform and its associated endpoints.
If you would instead rather work with an SDK in your preferred language, we have a Python and NodeJS SDK available. If you are using another language, please let us know.
General information about authentication and connection testing can be found below, along with a changelog for major updates.
The following are the four main API groups, and their main endpoints:
Archive API: for querying and purchasing satellite imagery captured some time in the past.
This includes the ability to:
- Search, for obtaining a list of satellite imagery available for the request’s search criteria
- New order, which creates a new order, and pays for purchasing imagery
- Batch Order, for ordering multiple scenes at the same time
Tasking API: for querying availability and ordering satellite imagery to be captured in the future.
- Search, for obtaining a list of possible capture opportunities for a target location, time period and conditions
- Order, for confirming and booking one of the opportunities obtained from search
- Batch Order, for confirming and booking a set of tasking opportunities in a single operation.
Orders API: for managing and downloading your past imagery orders.
- List orders, which will list all past and current orders on your account
- Get order, which will list the details and any associated resources of an order on your account
- Get resource, which requests download of a resource associated with an order, such as the imagery or its metadata
Collections API: for creating and managing collections of imagery that can be queried and explored as a discrete dataset.
- List Collections, which will list all collections on your account
- Collection Details, which will provide the details of an individual collection
- List Collection Items, which will list items (orders and scenes) within the collection
- Collection Item Details, which will provide details of an individual item within the collection
- Search Collection, which provides query and search functionality to find items within a collection
- Create Collections, for creating new data collections
- Add Collection item, to add orders to a collection
- Remove Collection Item, to remove them from the dataset
- Update Collection, to update labelling and descriptive details of the collection
- Delete Collection, to delete a collection
- Request Item Access, to request access to an order in a collection
- Collection Conformance, to view STAC standards compliance of the collection system
API Authentication
Making requests to the Arlula APIs requires providing API Authentication credentials for every request as part of the request header.
To obtain API credentials, you will need to create and API account in our system dashboard and be issued with API Credentials.
All requests to the API must be made via a https connection
Authentication is achieved by providing your API Key and API Password using the HTTP Basic Auth Mechanism.
Connection Testing
An endpoint is available at /api/test that does nothing other than check your authentication.
This is often useful if you want to check your setup prior to making actual requests.

Added new resource types:
- `img_jp2` for JPEG Core 200 format imagery, and
- `meta_bundle` for aggregated or otherwise bundled metadata
Version 2.0.2:
Updated order status labels to clarify state (‘manual’ for awaiting supplier non-automated response caused confusion)
Version 2.0.3:
Added additional resource types for scene geometry:

- Cloud cover percentage
Location
The area of interest can be provided in 5 ways:
- Search a point location using either an address, name, or coordinates.
- The Point Tool allows you to drop a pin at a location of interest
- The Bounding Box allows you to define an interest area by drawing a box
- The Polygon Tool allows you to define an area of interest by drawing a polygon.
- The File Upload Tool allows you to upload a KML, WKT or GeoJSON file containing one or more polygons.
