Socrata provides an API for city open data. For a dataset such as SF crime, see the API tab on top right. That provides you with the dataset identifier. Use the dataset identifier to grab specific tables for a given city_id (data.sfgov.org) - E.g., vw6y-z8j6 for SF 311 data. E.g., tmnf-yvry for SF Police data. 
%pip install -qU  sodapy

from langchain_community.document_loaders import OpenCityDataLoader

dataset = "vw6y-z8j6"  # 311 data
dataset = "tmnf-yvry"  # crime data
loader = OpenCityDataLoader(city_id="data.sfgov.org", dataset_id=dataset, limit=2000)

docs = loader.load()
