Gemini Google Maps Tool Skill

Purpose

Comprehensive guide for using gemini-google-maps-tool, a CLI and Python library that connects Gemini to Google Maps' database of 250+ million places worldwide for location-aware responses with accurate, up-to-date information.

When to Use This Skill

Use this skill when:

• Querying for location-based recommendations (restaurants, hotels, attractions)
• Generating itineraries with place-specific information
• Building applications that need location-aware AI responses
• Integrating Google Maps data into AI workflows
• Creating travel, food, or local business applications

Do NOT use this skill for:

• General Gemini queries without location context
• Tasks that don't involve places or geographical information
• Direct Google Maps API queries (this uses Gemini with Maps grounding)

CLI Tool: gemini-google-maps-tool

A production-ready CLI and Python library for querying Gemini with Google Maps grounding.

Installation

# Install globally with uv tool
uv tool install gemini-google-maps-tool

# Or from source
git clone https://github.com/dnvriend/gemini-google-maps-tool.git
cd gemini-google-maps-tool
uv tool install .

Prerequisites

• Python 3.14+
• uv package manager
• Gemini API Key from Google AI Studio

Quick Start

# Set API key
export GEMINI_API_KEY="your-api-key"

query - Query Gemini with Google Maps Grounding

Query Gemini with Google Maps integration for location-aware information about places, businesses, directions, and attractions.

Usage:

gemini-google-maps-tool query "QUERY" [OPTIONS]

Arguments:

• QUERY: The search query (required unless using --stdin)
• --lat-lon LAT,LON: Location coordinates in format "lat,lon" (e.g., "37.78193,-122.40476")
• --model {flash|flash-lite}: Model selection
  • flash: gemini-2.5-flash (more powerful, higher cost)
  • flash-lite: gemini-2.5-flash-lite (default, faster, cost-effective)
• -v, --verbose: Enable INFO logging (operation-level details)
• -vv: Enable DEBUG logging (detailed API calls, validation)
• -vvv: Enable TRACE logging (full HTTP traces, library internals)
• --text / -t: Output markdown text instead of JSON
• --stdin / -s: Read query from stdin

Examples:

# Basic query
gemini-google-maps-tool query "Best coffee shops in Amsterdam"

# With location context
gemini-google-maps-tool query "Italian restaurants nearby" \
  --lat-lon "52.37,4.89"

# Using different model
gemini-google-maps-tool query "Plan a day in NYC" --model flash

# Markdown output with sources
gemini-google-maps-tool query "Best museums in Paris" --text

# Verbose mode with grounding metadata
gemini-google-maps-tool query "Sushi restaurants" -v

# Debug mode with full details
gemini-google-maps-tool query "Hotels in London" -vv

# Trace mode with HTTP details
gemini-google-maps-tool query "Attractions in Rome" -vvv

# Reading from stdin (for pipelines)
echo "Best bakeries in San Francisco" | \
  gemini-google-maps-tool query --stdin

# Pipeline with jq
gemini-google-maps-tool query "Coffee shops" | \
  jq '.response_text'

Output Formats:

JSON (default):

{
  "response_text": "Here are some great coffee shops...",
  "grounding_metadata": {
    "grounding_chunks": [
      {
        "title": "Blue Bottle Coffee",
        "uri": "https://maps.google.com/?cid=...",
        "place_id": "places/ChIJ..."
      }
    ]
  }
}

Markdown (with --text):

Here are some great coffee shops...

completion - Generate Shell Completion Scripts

Generate shell completion scripts for Bash, Zsh, or Fish to enable tab-completion for commands and options.

Usage:

gemini-google-maps-tool completion {bash|zsh|fish}

Arguments:

• SHELL: Shell type (required) - bash, zsh, or fish

Examples:

# Bash - temporary (current session)
eval "$(gemini-google-maps-tool completion bash)"

# Bash - persistent
echo 'eval "$(gemini-google-maps-tool completion bash)"' >> ~/.bashrc

# Zsh - temporary
eval "$(gemini-google-maps-tool completion zsh)"

# Zsh - persistent
echo 'eval "$(gemini-google-maps-tool completion zsh)"' >> ~/.zshrc

# Fish - install to completions directory
gemini-google-maps-tool completion fish > \
  ~/.config/fish/completions/gemini-google-maps-tool.fish

# File-based (better performance)
gemini-google-maps-tool completion bash > \
  ~/.gemini-google-maps-tool-complete.bash
echo 'source ~/.gemini-google-maps-tool-complete.bash' >> ~/.bashrc

Output: Shell-specific completion script that can be evaluated or saved to a file.

Multi-Level Verbosity Logging

Progressive detail control for debugging and monitoring:

• No flag (default): WARNING level - only critical issues
• -v: INFO level - high-level operations, important events
• -vv: DEBUG level - detailed operations, API calls, validation steps
• -vvv: TRACE level - full request/response, library internals, HTTP traces

Examples:

# INFO: See which files are processed
gemini-google-maps-tool query "Best restaurants" -v

# DEBUG: See API call details and validation
gemini-google-maps-tool query "Hotels nearby" -vv

# TRACE: See full HTTP requests/responses
gemini-google-maps-tool query "Museums" -vvv

Google Maps Grounding

What is it? Google Maps grounding connects Gemini to Google Maps' database of 250+ million places worldwide, providing:

• Location-aware responses with accurate, up-to-date information
• Personalized recommendations tailored to specific areas
• Automatic citation generation with structured sources
• Seamless integration via Gemini's API

Grounding Metadata: With -v or --text, responses include:

• Grounding Chunks: Google Maps sources (title, URI, place_id)
• Grounding Supports: Text segments linked to sources
• Widget Context Token: For interactive maps integration

Example:

gemini-google-maps-tool query "Best pizza in Brooklyn" -v

Returns JSON with:

{
  "response_text": "...",
  "grounding_metadata": {
    "grounding_chunks": [
      {
        "title": "Roberta's Pizza",
        "uri": "https://maps.google.com/?cid=...",
        "place_id": "places/ChIJ..."
      }
    ],
    "grounding_supports": [...],
    "google_maps_widget_context_token": "..."
  }
}

---

Location Context

Provide location coordinates for personalized, location-aware responses:

Format: --lat-lon "latitude,longitude"

Examples:

# Amsterdam center
gemini-google-maps-tool query "Coffee shops nearby" \
  --lat-lon "52.37,4.89"

# San Francisco
gemini-google-maps-tool query "Italian restaurants" \
  --lat-lon "37.78,-122.40"

# Tokyo
gemini-google-maps-tool query "Sushi restaurants" \
  --lat-lon "35.68,139.76"

Coordinate Ranges:

• Latitude: -90 to 90
• Longitude: -180 to 180

---

Model Selection

Choose between two Gemini models:

flash-lite (default):

• Model: gemini-2.5-flash-lite
• Faster, more cost-effective
• Best for simple location queries
• Recommended for most use cases

flash:

• Model: gemini-2.5-flash
• More powerful and capable
• Best for complex queries and itinerary planning
• Higher cost

Examples:

# Default (flash-lite)
gemini-google-maps-tool query "Best restaurants"

# Explicit flash-lite
gemini-google-maps-tool query "Hotels" --model flash-lite

# Use flash for complex queries
gemini-google-maps-tool query "Plan a 3-day trip to Paris" \
  --model flash

---

Python Library Usage

Import and use programmatically in Python applications:

Basic Usage:

from gemini_google_maps_tool import get_client, query_maps

# Initialize client
client = get_client()

# Execute query
result = query_maps(
    client=client,
    query="Best coffee shops near me",
)

print(result.response_text)

With Location and Grounding:

from gemini_google_maps_tool import get_client, query_maps

client = get_client()

result = query_maps(
    client=client,
    query="Italian restaurants nearby",
    lat_lon=(37.78193, -122.40476),
    model="gemini-2.5-flash",
    include_grounding=True,
)

# Access response
print(result.response_text)

# Access grounding metadata
if result.grounding_metadata:
    for chunk in result.grounding_metadata.grounding_chunks:
        print(f"Source: {chunk.title} - {chunk.uri}")

Error Handling:

from gemini_google_maps_tool import (
    get_client,
    query_maps,
    ClientError,
    QueryError,
)

try:
    client = get_client()
    result = query_maps(client, "Best restaurants")
    print(result.response_text)
except ClientError as e:
    print(f"Client error: {e}")
except QueryError as e:
    print(f"Query error: {e}")
