mapradar 0.1.2

Turn addresses into coordinates and find nearby amenities using Google Maps API

Mapradar

Turn addresses into coordinates and find nearby banks, hospitals, and other amenities.

---

What It Does

Mapradar is a location intelligence library. Give it an address like "Shibuya, Tokyo" and it returns:

1. Coordinates - Latitude and longitude
2. Nearby Services - Banks, hospitals, schools, fuel stations within a radius
3. Distance - How far each service is from your location

Built in Rust. Works in both Python and Rust.

Installation

Python

uv add mapradar

Rust

[dependencies]
mapradar = { version = "0.1", default-features = false }
tokio = { version = "1", features = ["full"] }

Note: Use default-features = false for pure Rust (no Python bindings).

From Source

Python:

git clone https://github.com/iamprecieee/mapradar
cd mapradar
uv add maturin
maturin develop

Rust:

[dependencies]
mapradar = { git = "https://github.com/iamprecieee/mapradar" }

Usage

Python

import asyncio
from mapradar import MapradarClient, SearchQuery, ServiceType

async def main():
    client = MapradarClient("YOUR_GOOGLE_MAPS_API_KEY")
    
    # Find banks and hospitals near an address
    query = SearchQuery.from_address("Shibuya, Tokyo")
    intel = await client.fetch_intelligence(
        query,
        service_types=[ServiceType.Bank, ServiceType.Hospital],
        radius_km=3.0
    )
    
    print(f"Location: {intel.location.address}")
    print(f"Country: {intel.location.country}")
    for service in intel.nearby_services:
        print(f"  {service.name} - {service.distance_km:.2f} km")

asyncio.run(main())

More Examples

Geocoding only:

location = await client.geocode("1 Marina, Lagos")
print(location.latitude, location.longitude, location.country)

Reverse geocoding:

location = await client.reverse_geocode(6.4541, 3.3947)
print(location.address, location.country)

JSON-RPC format (for microservices):

response = await client.geocode_rpc("Lekki, Lagos", id="req-123")
print(response.to_json())

Rust

use mapradar::client::MapradarClient;
use mapradar::models::{SearchQuery, ServiceType};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = MapradarClient::new("YOUR_API_KEY".to_string());
    
    let location = client.geocode_async("Times Square, NYC").await?;
    println!("{}, {} ({})", location.latitude, location.longitude, location.country);
    
    Ok(())
}

FAQ

What APIs do I need enabled?

Enable these in Google Cloud Console:

• Geocoding API
• Places API (New)

Is there rate limiting?

Mapradar does not rate limit. Your Google Maps API quota applies. Use the built-in cache to reduce calls.

Does caching persist across restarts?

No. Cache is in-memory only. It persists for the lifetime of your MapradarClient instance.
