King County Food Safety

Command-line access to King County food facility ratings, inspection history, violations, geocoding, and raw ArcGIS feature-layer queries.

The command is king-county-food-safety. It reads King County's public ArcGIS services directly, needs no API key, and has no runtime dependencies outside the Python standard library.

Start Here

Use Python 3.12 or newer.

Install

Install from PyPI with the tool of your choice:

uv tool install king-county-food-safety

pipx install king-county-food-safety

pip install king-county-food-safety

Any of these puts the king-county-food-safety command on your path.

Run the Command

king-county-food-safety ratings

Run from a checkout without installing:

PYTHONPATH=src python3 -m king_county_food_safety ratings

Run the packaged console script through uv in a checkout:

uv run king-county-food-safety ratings

Network options are root-level flags. Put them before the subcommand:

king-county-food-safety --timeout 10 --retries 2 export facilities --jsonl

Expected network and API failures print one-line errors. Add --verbose before the subcommand to get a traceback.

king-county-food-safety --verbose search pizza

Find Nearby Facilities

Shape Output

Typed commands default to tables for humans. Use a machine format when piping into other tools:

• --json prints a JSON array.
• --jsonl prints one JSON object per line.
• --csv prints comma-separated records.
• --tsv prints tab-separated records.

Use --fields to project flat output fields:

king-county-food-safety near "401 5TH AVE" --city Seattle \
  --jsonl \
  --fields distance_miles,business_record_id,business_name,rating

Use --fields '*' to print every normalized field for a typed command:

king-county-food-safety inspections PFE-PR-3126839 --jsonl --fields '*'

Batch Input

inspections --stdin reads facility IDs from stdin. violations --stdin reads inspection serial numbers from stdin. Both commands batch rows into ArcGIS IN (...) queries, so pipelines avoid one request per input row.

king-county-food-safety near "401 5TH AVE" --city Seattle \
  --radius 0.5 \
  --jsonl \
  --fields business_record_id \
  | jq -r '.business_record_id' \
  | king-county-food-safety inspections --stdin --jsonl --fields inspection_serial_number \
  | jq -r '.inspection_serial_number' \
  | king-county-food-safety violations --stdin --jsonl

facility, inspections, and violations also accept --input-file with one ID per line:

king-county-food-safety facility --input-file watchlist.txt --jsonl
king-county-food-safety inspections --input-file watchlist.txt --limit 1 --jsonl

Query and Export Raw Data

query is the escape hatch for ArcGIS filtering. By default it prints the raw ArcGIS JSON payload:

king-county-food-safety query facilities \
  --where "Business_Grade = 'Needs to Improve'" \
  --out-fields Business_Record_ID,Business_Name,Business_Address,Business_City,Business_Grade \
  --limit 10

Add a machine format to flatten ArcGIS features into records:

king-county-food-safety query facilities \
  --where "Business_Grade = 'Needs to Improve'" \
  --out-fields Business_Record_ID,Business_Name,Business_Grade \
  --jsonl

Use query --all or export to page through a result set:

king-county-food-safety export inspections \
  --where "Inspection_Result = 'Unsatisfactory'" \
  --out-fields Business_Record_ID,Inspection_Date,Inspection_Score,Inspection_Result \
  --jsonl \
  --manifest inspections.manifest.json > inspections.jsonl

Raw ArcGIS aggregations use --group-by and repeatable --stat values:

king-county-food-safety export facilities \
  --group-by Business_City,Business_Grade \
  --stat count:OBJECTID:count \
  --csv

--stat uses statisticType:onStatisticField:outStatisticFieldName.

Snapshot and Diff Data

snapshot writes JSONL and, by default, a sidecar manifest. The manifest records when the data was fetched, which layer was queried, and which query parameters were used.

king-county-food-safety snapshot facilities --output snapshots/facilities.jsonl

diff compares two JSONL or JSON-array snapshots and emits added, removed, and changed records. It can infer common keys such as OBJECTID, Business_Record_ID, business_record_id, and Inspection_Serial_Num.

king-county-food-safety diff snapshots/facilities-old.jsonl snapshots/facilities.jsonl --key OBJECTID --jsonl

Reference

Command Reference

Use --help on any command for exact options:

king-county-food-safety search --help
king-county-food-safety query --help

Layer Reference

The inspections command matches the public map's default inspection-history filter. Use --all to inspect every row returned by the API.

Limit Reference

• --page-size controls one ArcGIS request and must be between 1 and 2000.
• query --limit without --all is a single ArcGIS request limit and must be between 1 and 2000.
• query --all --limit, export --limit, and snapshot --limit are total record caps and can be larger than one page.

Service Constraints

The CLI depends on King County's public food safety map: https://kingcounty.gov/en/dept/dph/health-safety/food-safety/search-restaurant-safety-ratings. Field names and public filtering rules can change when King County updates the map.

Use king-county-food-safety metadata <layer> to inspect the current schema. Use query when the typed commands do not cover the ArcGIS query shape you need.

The CLI does not cache responses. Every command reads current data from the public service.

Stability and Versioning

This project follows semantic versioning. The public contract is the command-line interface: command and alias names, flags, output formats, exit codes, and the deterministic, sorted JSON shape. Breaking any of these requires a major version bump.

The data itself is owned by King County. Field names and public filtering rules can change when the county updates its map, and those upstream changes are not treated as breaking changes to this CLI. Use metadata <layer> to inspect the current schema and query for shapes the typed commands do not cover.

Development

Run Tests

PYTHONPATH=src python3 -m unittest discover -s tests

Run tests with 100% coverage enforced:

uv run --no-project --with coverage env PYTHONPATH=src \
  coverage run --source=src/king_county_food_safety -m unittest discover -s tests
uv run --no-project --with coverage coverage report --fail-under=100

Lint and Format

uv run --no-project --with ruff ruff check .
uv run --no-project --with ruff ruff format .

The dev extra (pip install ".[dev]") installs build, coverage, mypy, and ruff.

Releasing

Releases are automated through GitHub Actions. Bump version in pyproject.toml, commit, then push a matching tag:

git tag v1.2.3
git push origin v1.2.3

The release workflow verifies the tag matches the package version, runs the coverage gate, builds distributions, publishes to PyPI via trusted publishing, and creates the GitHub release.
