This is an API for interacting with the ESPA ordering system.

User API

The User API is public facing and available for anyone to code and interact with.
Version 1 provides the minimum functionality necessary to determine available products from a list of inputs, place orders, and view order status. There are endpoints for providing available projections, resampling methods, and output formats.

All user interactions with API functions must be accompanied by valid credentials. Accounts are managed in the USGS EROS Registration system.

Quick Unix Walk-through

The ESPA ordering system provides an API for users to interact with using simple HTTP communications through the programming language of their choice.

  1. To find what products ESPA can produce for a given Landsat acquisition: /available-products
  2. If the acquisition can be processed into a desired product, create a processing order request: /order
  3. When processing has completed, get the download URL while the output is still available: /item-status

For a more detailed list of User API operations, see the Available Resources List.

For a language-specific (python) example, please see an API Demo.
