This repository contains the official specification for the Sensor Tasking API (STAPI), a JSON-based web API for discovering and ordering spatio-temporal data products from remote sensing providers.

STAPI enables users to:

• Discover available Products from satellite and airborne data providers
• Request Opportunities to understand what data can be collected
• Submit Orders for new tasking or archived data processing

The specification is designed to work alongside STAC - while STAC handles existing data, STAPI handles ordering future data or processing tasks.

Visit the STAPI documentation site to read the full specification.

To run the documentation site locally:

uv run mkdocs serve

See CONTRIBUTING.md for detailed development instructions.
