Steps
Register for an EROS/ERS account and generate an M2M application token (the classic password-based login endpoint is deprecated in favor of login-token).
POST to the login-token endpoint with your username and application token to obtain a session API key, then include it on subsequent calls.
POST to dataset-search or dataset-filters to identify the correct datasetName (e.g. a Landsat Collection 2 Level-2 dataset).
POST to scene-search with the datasetName plus a sceneFilter (spatial bounding box/geometry, acquisition date range, cloud cover, etc.) to get matching scene entityIds.
Call download-options and download-request for the returned entityIds/datasetName to get downloadable URLs, then poll download-search/download-retrieve until the URLs are ready.
Known gotchas
The legacy password-only login endpoint was deprecated; new integrations must use login-token with an application token, not a bare password.
The M2M API returns metadata and download URLs only — actual file transfer must be done separately (wget/cURL) against those URLs, which can expire.
All requests use JSON POST bodies with application/json content type, not query-string GETs — a common integration mistake with this API.
