Support for MultiPolygon

[zacdezgeo]

@andresfchamorro @bpstewar; can you provide the exact requests used to reproduce the bug and provide a little more description?

Thanks for opening the issue, I will open a new one for small polygons as it's different and probably minor.

Do you think the API could support multi polygons? There are likely going to be many admin areas like this one with coastal features.

The response is 422 but the text for the exception doesn't yield anything. The json does say Input should be 'Polygon

from typing import Dict
import requests
import geopandas as gpd
import pandas as pd
from geojson_pydantic import Feature, Polygon

SUMMARY_ENDPOINT = f"{BASE_URL}/summary"

iso3 = 'KEN'
adm = 'ADM1'
url = f'https://www.geoboundaries.org/api/current/gbOpen/{iso3}/{adm}/'
res = requests.get(url).json()
adm = gpd.read_file(res['gjDownloadURL'])
aoi = adm.loc[42]

feature = {
    "type": "Feature",
    "geometry": aoi.geometry.__geo_interface__,
    "properties": { key: value for key, value in aoi.items() if key != 'geometry' }
}

AOIModel = Feature[Polygon, Dict]

# Define the Request Payload
request_payload = {
    "aoi": feature,
    "spatial_join_method": "centroid",

}

# Get Summary Data
response = requests.post(SUMMARY_ENDPOINT, json=request_payload)
if response.status_code != 200:
    raise Exception(f"Failed to get summary: {response.text}")

summary_data = response.json()
df = pd.DataFrame(summary_data)
