This Docker image provides a web server that grants access to the libpostal library, enabling the parsing and normalization of street addresses globally. It need at least 2Gb of RAM (use 4GB for safety)

Ready docker image

docker pull ghcr.io/le0pard/postal_server:latest

To expand address strings into normalized forms suitable for geocoder queries, use the /expand endpoint with the address query parameter. For example, to expand the address "Quatre-vingt-douze Ave des Ave des Champs-Élysées":

GET /expand?address=Quatre-vingt-douze%20Ave%20des%20Ave%20des%20Champs-Élysées

[
  "92 avenue des avenue des champs-elysees",
  "92 avenue des avenue des champs elysees",
  "92 avenue des avenue des champselysees"
]

This will provide the expanded and normalized addresses ready for geocoding queries.

To parse addresses into components, use the /parse endpoint with the address query parameter. For example, to parse the address "781 Franklin Ave Crown Heights Brooklyn NY 11216 USA":

GET /parse?address=781%20Franklin%20Ave%20Crown%20Heights%20Brooklyn%20NY%2011216%20USA

[
  {
    "label": "house_number",
    "value": "781"
  },
  {
    "label": "road",
    "value": "franklin ave"
  },
  {
    "label": "suburb",
    "value": "crown heights"
  },
  {
    "label": "city_district",
    "value": "brooklyn"
  },
  {
    "label": "state",
    "value": "ny"
  },
  {
    "label": "postcode",
    "value": "11216"
  },
  {
    "label": "country",
    "value": "usa"
  }
]

This will break down the address into its individual components.

Endpoint /health can be use to check webserver healthcheck (like in k8s env):

$ curl http://localhost:8000/health
{"status":"ok"}

You can set up either basic authentication or bearer token authentication to protect your web server, while keeping the /health endpoint public
