The persons with significant control of a UK company exactly as the public register publishes them, active and ceased: name, kind (individual, corporate entity, legal person or super-secure person), status, notified and ceased dates, nature of control, month and year of birth, nationality, country of residence, correspondence address, and for corporate entities their governing law, legal form and registration details. Companies exempt from the requirement come back with the register's exemption text and no entries.
Every response includes credits_used: the credits this call cost.
Parameters
name

numberrequired
string
UK company number, 8 characters (e.g. 08804411 or SC123456). Example: 08804411
import os, requests
res = requests.get(
"https://api.api.sh/companies-house/v1/pscs",
params={"number": "08804411"},
headers={"x-api-key": os.environ["APISH_KEY"]},
timeout=120,
)
res.raise_for_status()
data = res.json()
const url = new URL("https://api.api.sh/companies-house/v1/pscs");
url.searchParams.set("number", "08804411");
const res = await fetch(url, { headers: { "x-api-key": process.env.APISH_KEY } });
if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);
const data = await res.json();
Response
A JSON object with the fields described above, plus raw (the source's own data), cached, fetched_at and credits_used. Errors return {"success": false, "error": "…"} with the HTTP status (see errors). A lookup that ran but found nothing (404) costs the price above; refused calls and errors on our side are free (what's charged).
The fastest way to see the full response is the playground: it runs this endpoint with your account and shows the exact JSON.
