statwrapper 0.1.1

A completely dependency-free unified wrapper around common statistical api types

statwrapper

statwrapper is a dependency-free Python library that provides a unified interface for common statistical API families. It currently ships wrapper support for:

• pxweb
• pxweb2
• dst
• eurostat

The package standardizes three operations across providers:

• health checks
• dataset discovery
• dataset metadata resolution

Installation

pip install statwrapper

Quick Start

import asyncio

from statwrapper import StatWrapper


async def main() -> None:
    wrapper = StatWrapper()

    discovered = await wrapper.discover_datasets("scb", "en")
    first = discovered[0]

    metadata = await wrapper.resolve_dataset_metadata(first)
    print(metadata.label)
    print(metadata.dimension_ids)


asyncio.run(main())

Public API

StatWrapper

from statwrapper import StatWrapper

wrapper = StatWrapper()

Methods:

• await wrapper.discover_datasets(provider_code, language, task_id=None)
• await wrapper.resolve_dataset_metadata(discovered, task_id=None)
• wrapper.get_provider(provider_code)
• wrapper.get_wrapper(provider_code, language)

Convenience Functions

from statwrapper import discover_provider_datasets, get_datasets

• await discover_provider_datasets(provider_code, language)
• get_datasets(provider_code, language)

Request Layer

The default request layer is a stdlib-backed async helper:

from statwrapper import RateLimitedSession

StatWrapper uses RateLimitedSession automatically, but you can inject your own session object if it exposes:

• async def get_json(url, **kwargs)
• async def get_text(url, **kwargs)
• async def get_bytes(url, **kwargs)

Provider Registry

Provider metadata is loaded from PROVIDERS.json. During development, the package reads the repository file. In built distributions, the same data is bundled inside the package.

Development

Run tests:

python -m pytest tests/unit tests/integration -q

Build locally:

python -m build

Publishing

PyPI publishing is handled by GitHub Actions through .github/workflows/pypi_publish.yml and the repository secret PYPI_API_TOKEN.
