Requires the requests library (pip install requests).

Fetch a single people group

import requests

response = requests.get(
    "https://peoplegroups.org/wp-json/pg/v1/people-groups/PG012345"
)
response.raise_for_status()

group = response.json()
print(group["NmDisp"])   # Nateni
print(group["Ctry"])     # Benin
print(group["LPIname"])  # Pioneer Unreached People Group

Page through all people groups

import requests

BASE_URL = "https://peoplegroups.org/wp-json/pg/v1/people-groups"
page = 1
all_groups = []

while True:
    response = requests.get(BASE_URL, params={"page": page, "per_page": 250})
    response.raise_for_status()

    batch = response.json()
    all_groups.extend(batch)

    total_pages = int(response.headers.get("X-WP-TotalPages", 1))
    if page >= total_pages:
        break
    page += 1

print(f"Fetched {len(all_groups)} people groups")

Uses the native fetch API (Node 18+). No dependencies required.

Fetch a single people group

const response = await fetch(
  "https://peoplegroups.org/wp-json/pg/v1/people-groups/PG012345"
);

if (!response.ok) {
  const error = await response.json();
  throw new Error(error.message);
}

const group = await response.json();
console.log(group.NmDisp);   // Nateni
console.log(group.Ctry);     // Benin
console.log(group.LPIname);  // Pioneer Unreached People Group

Page through all people groups

const BASE_URL = "https://peoplegroups.org/wp-json/pg/v1/people-groups";
let page = 1;
let totalPages = 1;
const allGroups = [];

do {
  const response = await fetch(`${BASE_URL}?page=${page}&per_page=250`);
  const batch = await response.json();
  allGroups.push(...batch);

  totalPages = parseInt(response.headers.get("X-WP-TotalPages") ?? "1", 10);
  page++;
} while (page <= totalPages);

console.log(`Fetched ${allGroups.length} people groups`);

Fetch a single people group (WordPress context)

$response = wp_remote_get(

    error_log( $response->get_error_message() );

$group = json_decode( $json, true );

Page through all people groups

serde_json = "1"
tokio = { version = "1", features = ["full"] }

Fetch a single people group

    println!("{}", group["NmDisp"]);   // "Nateni"
    println!("{}", group["Ctry"]);     // "Benin"
    println!("{}", group["LPIname"]); // "Pioneer Unreached People Group"

    Ok(())
