parsimony-bls 0.4.0

U.S. Bureau of Labor Statistics connector for the parsimony framework

parsimony-bls

US Bureau of Labor Statistics connector — labor market, employment, inflation (CPI), and producer price time series.

Part of the parsimony-connectors monorepo. Distributed standalone on PyPI as parsimony-bls.

Connectors

Name	Kind	Description
bls_fetch	fetch	Fetch a single BLS time series by series_id between two years.
enumerate_bls	enumerator	Enumerate popular BLS series across all surveys via the /surveys and /timeseries/popular endpoints.

Install

pip install parsimony-bls

Pulls in parsimony-core>=0.4,<0.5 automatically. Verify discovery:

python -c "from parsimony import discover; print([p.name for p in discover.iter_providers()])"

Configuration

The API key is optional — the plugin works without one but registering gives you higher rate limits.

export BLS_API_KEY="<your-key>"   # optional

Quick start

import asyncio
from parsimony_bls import CONNECTORS

async def main():
    connectors = CONNECTORS.bind_env()
    # LNS14000000 = US unemployment rate (seasonally adjusted)
    result = await connectors["bls_fetch"](
        series_id="LNS14000000",
        start_year="2020",
        end_year="2024",
    )
    print(result.data.head())

asyncio.run(main())

For multi-plugin composition (autoloads everything installed):

from parsimony import discover
connectors = discover.load_all().bind_env()
