docs menu

GET https://api.api.sh/gleif/v1/isins

1 credit / call government & registries try it in the playground →

The ISINs (securities) issued under an LEI, with the total. Pass next_page back as page; null on the last page.

Every response includes credits_used: the credits this call cost.

Parameters

name	type	description
`lei`required	string	Issuer's LEI. Example: `HWUPKR0MPOU8FGXBT394`
`limit`	integer	Results per page, 1-200. Example: `100`
`page`	integer	Page number, starting at 1. Pass `next_page` back as `page`; it is null on the last page. Example: `1`

Every endpoint also takes fresh, raw, fields (see lean responses and caching).

Example

curl "https://api.api.sh/gleif/v1/isins?lei=HWUPKR0MPOU8FGXBT394" \
  -H "x-api-key: $APISH_KEY"

import os, requests

res = requests.get(
    "https://api.api.sh/gleif/v1/isins",
    params={"lei": "HWUPKR0MPOU8FGXBT394"},
    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/gleif/v1/isins");
url.searchParams.set("lei", "HWUPKR0MPOU8FGXBT394");

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.
