# stac-fastapi-types — Core API for stac-fastapi modules.

License: permissive · Maintenance: active · Downloads: 96.9K/mo

## What it is and what it does

stac-fastapi-types is a core library that defines the type system and Pydantic data models for the STAC FastAPI implementation. It sits at the foundation of STAC API servers, providing standardized schemas for spatiotemporal asset catalogs—collections of geospatial data indexed by time and location. The package depends on FastAPI, Pydantic, attrs, iso8601, and starlette to deliver these models, and is designed to be used by other stac-fastapi modules that build complete server implementations on top of it.

Developers typically install this package as a dependency when building STAC API services or when integrating with other stac-fastapi components. It is not a standalone application but rather a foundational library that enforces schema consistency across STAC catalog implementations.

Use it for:

- Building a STAC API server that indexes geospatial datasets by time and location
- Integrating STAC catalog validation into a geospatial data pipeline using Pydantic models
- Extending stac-fastapi with custom STAC API endpoints while maintaining schema compliance
- Consuming STAC API responses in a client application that validates catalog structure

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides core type definitions and data models for building STAC API servers using FastAPI, enabling standardized geospatial catalog interfaces.

Yes, if you are building or extending a STAC API server or integrating with stac-fastapi components. The package is actively maintained, has no known vulnerabilities, uses a permissive MIT license, and carries low install friction. Install it as a dependency of a larger STAC implementation.

## Install

pip install stac-fastapi-types
uv add stac-fastapi-types
poetry add stac-fastapi-types

## Installing stac-fastapi-types

Before you install: Low install friction with a pure-Python wheel distribution. Active maintenance with a recent release 11 days ago and last commit on 2026-08-13. Supports current Python versions 3.11–3.14.

License in practice: MIT license permits commercial and private use with minimal restrictions, making it suitable for most deployment scenarios.

Quickstart:

pip install stac-fastapi-types

from stac_fastapi_types import core
import fastapi

app = fastapi.FastAPI()
# Use stac-fastapi-types models in your STAC API implementation

Requires Python 3.11 or later.

Verify before relying:

- Whether this package is intended for end-user applications or primarily as a dependency for other STAC server implementations
- What specific STAC API specification version(s) this release implements
