Google Earth Engine
Google Earth Engine combines a multi-petabyte catalog of satellite imagery and geospatial datasets with a planetary-scale analysis engine, accessed through Python and JavaScript client libraries or a batch REST API rather than a simple key-gated JSON endpoint. Access requires a Google Cloud project with the Earth Engine API enabled and OAuth 2.0 credentials (user, service account, or Cloud IAM) — there is no bare API-key mode — and since 2025 noncommercial projects must periodically re-verify eligibility to keep free-tier access.
