  -H "Authorization: Bearer $AI4M_API_KEY"

shapes = client.get_lga_boundaries("KN")
for feature in shapes["features"]:
    print(feature["properties"]["lgaCode"])

const shapes = await client.getLgaBoundaries("KN");
for (const feature of shapes.features) {
  console.log(feature.properties.lgaCode);
}

shapes, err := client.LGABoundaries(ctx, "KN")
if err != nil {
  log.Fatal(err)
}
fmt.Println(len(shapes["features"].([]any)), "LGAs")

Response

Field	Type	Description
`type`	string	Always `FeatureCollection`
`source`	string	Where the shapes come from
`features[].properties.lgaCode`	string	LGA identifier, matching `lga_code` in the risk endpoints
`features[].properties.lga`	string	LGA name
`features[].properties.state`	string	Two-letter state code
`features[].geometry`	object	A GeoJSON `Polygon` or `MultiPolygon`, in longitude and latitude (WGS 84)

Errors

Code	Status	When
`UNKNOWN_STATE`	404	`state` is missing or is not a valid state code
`SCOPE_REQUIRED`	403	The key does not include the scope this endpoint needs

Any request can also return 401 for a bad key and 429 when a limit is reached. See Errors.
