Geocoding API

Request

Naurt data can be searched via a POST request to the final-destination endpoint. Again, data should be provided as a JSON in the body of the request and not in the URL.

JSON
POST  https://api.naurt.net/final-destination/v1
Content-Type: application/json
Authorization: <API_KEY_HERE>
{
  "address_string": Option<String>, 
  "country": Option<String>,
  "latitude": Optional<Float>,
  "longitude": Optional<Float>,
  "distance_filter": Optional<Float>,
  "additional_matches": Optional<Bool>,
}

Parameters

ParameterTypeOptionalDefaultDescription
latitudefloatYesNoneA valid latitude in WGS84 degrees. Range: -90 <= lat <= 90.
longitudefloatYesNoneA valid longitude in WGS84 degrees. Range: -180 <= lon < 180.
distance_filterfloatYes5000A distance in metres (larger than 0) within which you wish to search for POIs. When a filter is applied a latitude and longitude must also be provided. Maximum value of 25000 metres.
address_stringStringYesNoneAn address string. Good formatting, spelling, and completeness will offer the best search results.
additional_matchesBooleanYesFalseProvides up to 4 results beyond what Naurt classifies as the best_match.
countryStringYesNoneOptional but strongly suggested two digit country code which helps with performance.
Currently supported country tags are
  • UK: United Kingdom
  • SG: Singapore

Example

CURL
curl -XPOST \
-H "Content-type: application/json" \
-H "Authorization: <API_KEY_HERE>"  \
-d '{"naurt_address_string": "Westminster Hall" ,"country": "UK"}' \
'https://api.naurt.net/final-destination/v1'

Response

Success

A 200 response code indicates a successful response with the format as follows.

JSON
{
  "best_match": Optional<DESTINATION RESPONSE FORMAT>,
  "additional_matches": Optional<List<DESTINATION RESPONSE FORMAT>>,
  "contributors": Optional<List<String>>,
  "version": Optional<String>
}

Naurt will identify the single best match for you. You will only have an additional_matches field if you set additional_matches to true in the request.

The DESTINATION RESPONSE FORMAT is

JSON
{
  "id": String,
  "address": String,
  "geojson": GeoJSON,
  "distance": Optional<float>
}
  • Note that the address field is the normalised address and may not match the address you searched with.
  • Distance will only be present if you search with a latitude and longitude and will be the distance of the destination from that position in metres.

Failure

A response code other than 200 indicates a failure to retrieve the requested destination.

JSON
401 Unauthorized 
{"error":"Please ensure the request contains a valid API key."}

If there are no destinations available which match the search term, the response JSON will not contain any results, but instead a "naurt_info" message.

JSON
{"naurt_info":"Successful request. No destinations match search conditions."}

Search Restrictions

Destinations requested via the API are subject to some restrictions.

  • No more than 300 requests per minute can be sent to this endpoint per API key. This limit can be adjusted by speaking to our support team.
  • Currently there is a maximum return of 5 destinations per request.

Code Examples

Below are some basic coded templates showing how to use the final-destination API from different languages.

Python
import requests
import json

url = "https://api.naurt.net/final-destination/v1"

payload = json.dumps({
  "latitude": 11.0,
  "longitude": 12.0,

})
headers = {'Content-Type': 'application/json', 'Authorization':'<API_KEY_HERE>'}

response = requests.request("POST", url, headers=headers, data=payload)

print(response.text)
Javascript
var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/json");
myHeaders.append("Authorization", "<API_KEY_HERE>");
var raw = JSON.stringify({
  "latitude": 11.0,
  "longitude": 12.0
});

var requestOptions = {
  method: 'POST',
  headers: myHeaders,
  body: raw,
  redirect: 'follow'
};

fetch("https://api.naurt.net/final-destination/v1", requestOptions)
  .then(response => response.text())
  .then(result => console.log(result))
  .catch(error => console.log('error', error));
Rust
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = reqwest::Client::builder()
        .build()?;

    let mut headers = reqwest::header::HeaderMap::new();
    headers.insert("Content-Type", "application/json".parse()?);
    headers.insert("Authorization", "<API_KEY_HERE>".parse()?);
    let data = r#"{
    "latitude": 11.0,
    "longitude": 12.0
    }"#;

    let json: serde_json::Value = serde_json::from_str(&data)?;

    let request = client.request(reqwest::Method::POST, "https://api.naurt.net/final-destination/v1")
        .headers(headers)
        .json(&json);

    let response = request.send().await?;
    let body = response.text().await?;

    println!("{}", body);

    Ok(())
