https://allemannsdata.com/wiki/kilder/arkivverket/search_census_persons/?query={query}&first_name={first_name}&last_name={last_name}&sex={sex}&birth_year={birth_year}&birth_place={birth_place}&residence={residence}&occupation={occupation}&match=all&limit=25&offset=0

Generated JavaScript, Python and response structure

Use JSON when the user requests code, machine-readable data, value extraction or further computation. Use the HTML GET page to identify the correct source and verify parameters.

Example for generated JavaScript and Python

https://allemannsdata.com/wiki/api/v1/kilder/arkivverket/search_census_persons?query={query}&first_name={first_name}&last_name={last_name}&sex={sex}&birth_year={birth_year}&birth_place={birth_place}&residence={residence}&occupation={occupation}&match=all&limit=25&offset=0

Replace URL placeholders and remove unused optional parameters.

JavaScript in a dashboard

const url = "https://allemannsdata.com/wiki/api/v1/kilder/arkivverket/search_census_persons?query={query}&first_name={first_name}&last_name={last_name}&sex={sex}&birth_year={birth_year}&birth_place={birth_place}&residence={residence}&occupation={occupation}&match=all&limit=25&offset=0";
const response = await fetch(url);
if (!response.ok) {
  const failure = await response.json();
  throw new Error(`${failure.error.code}: ${failure.error.message} ${failure.suggestion}`);
}
const result = await response.json();
const data = result.data;

Python without additional packages

import json
from urllib.request import urlopen

url = "https://allemannsdata.com/wiki/api/v1/kilder/arkivverket/search_census_persons?query={query}&first_name={first_name}&last_name={last_name}&sex={sex}&birth_year={birth_year}&birth_place={birth_place}&residence={residence}&occupation={occupation}&match=all&limit=25&offset=0"
with urlopen(url) as response:
    result = json.load(response)
data = result["data"]

How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the search_census_persons lookup

Replace the placeholders in the HTML GET template; remove optional parameters you do not need.
Check types, units, limits and ID formats in the parameter table.
Follow linked results to canonical pages before combining sources.

Misreading to avoid: An empty list means "no results for this lookup". An error message or unavailable source does not mean the data does not exist.

Source-specific next step

Go to the source page for other operations. Use the JSON template only after the HTML result shows that the parameters and source are correct.
