What it is and what it does

stac-fastapi-extensions is a FastAPI-based implementation of the STAC API specification. It provides extension modules that build on top of stac-fastapi-api and stac-fastapi-types to enable developers to construct APIs for cataloging and serving geospatial data with temporal dimensions.

The package targets developers, researchers, and IT professionals working with geospatial data. It requires Python 3.11 or later and has low installation friction, depending only on two core runtime dependencies. The project is actively maintained with recent updates and is part of the stac-utils ecosystem.

Use it for:

Build a geospatial data catalog API that exposes satellite imagery or spatiotemporal assets with STAC compliance
Extend a FastAPI application to serve STAC-compliant search and discovery endpoints for scientific data
Implement custom STAC API extensions for domain-specific metadata or query requirements

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides FastAPI extensions for the STAC API specification, enabling you to build spatiotemporal asset catalog APIs.

Yes, if you are building a STAC API with FastAPI. The package has low install friction, active maintenance, no known vulnerabilities, and permissive MIT licensing. Install only if you need STAC API extensions; if you need only the base STAC API, stac-fastapi-api may suffice.
