BroadbandMap Cell Coverage

Status: Preliminary skill (v0.x). This is an intentionally small first release and is expected to evolve quickly.

Use this skill to answer: “How good is cell coverage here?” for a specific location.

Quick workflow

1. Resolve location to coordinates (lat/lon).
2. Run scripts/cell_coverage_lookup.py to call the coverage API.
3. Summarize key results:
   • top carriers
   • network tech (4G/5G)
   • confidence/quality fields if present
4. Include caveats when API fields are missing or endpoint behavior is unknown.

Run the script

python3 scripts/cell_coverage_lookup.py --lat 39.7392 --lon -104.9903

Default endpoint used by this skill:

• GET /api/v1/location/cell?lat={lat}&lng={lng}
• Optional filters: network (att|verizon|t-mobile|us-cellular|dish|gci|cellcom|c-spire), tech (4g|5g)

Address mode (uses OpenStreetMap Nominatim geocoding first):

python3 scripts/cell_coverage_lookup.py --address "Denver, CO"

Optional overrides and filters:

python3 scripts/cell_coverage_lookup.py \
  --lat 39.7392 --lon -104.9903 \
  --network verizon \
  --tech 5g \
  --format report

Advanced endpoint overrides:

python3 scripts/cell_coverage_lookup.py \
  --lat 39.7392 --lon -104.9903 \
  --base-url "https://broadbandmap.com" \
  --endpoint "/api/v1/location/cell" \
  --param-lat lat --param-lon lng \
  --api-key "$BROADBANDMAP_API_KEY"

Output contract

The script prints JSON by default with:

• input: address/lat/lon used
• request: final URL and query params
• response: parsed API JSON (or raw body)
• summary: best-effort normalized fields (providers, technologies, notes)
• errors: any recoverable errors

Use --format report for a concise human-readable output.

Example commands

# Basic lookup by address
python3 scripts/cell_coverage_lookup.py --address "Austin, TX" --format report

# Filter to one network and 5G only
python3 scripts/cell_coverage_lookup.py --address "Seattle, WA" --network verizon --tech 5g --format report

# Raw JSON for automation/pipelines
python3 scripts/cell_coverage_lookup.py --lat 34.0522 --lon -118.2437 --format json

Known limitations

• This skill is a preliminary v0.x release and will be iterated/enhanced.
• API is alpha and may change schema/limits without notice.
• Default public limit is low (~60 requests/hour/IP).
• Coverage maps are modeled estimates and may differ from real-world signal.

Response style

When replying to users:

• Start with a one-paragraph answer.
• Then list providers/technologies in bullets.
• End with one caveat sentence: coverage maps are estimates and real-world signal may vary.
