  description: >-
    The EarthCache API gives developers a single, provider-agnostic interface to
    discover, price, order, and deliver commercial satellite imagery and
    geospatial data. Create an archive Search over historical imagery, stand up a
    Pipeline that monitors an area of interest and delivers imagery on a
    schedule, retrieve interval results with analytics and metadata download
    URLs, estimate cost, manage reusable output configurations and saved
    locations, and subscribe to platform events via callback URIs. All requests
    are authenticated with an `x-api-key` header. Imagery is billed per square
    kilometre with resolution-based purchase minimums.
