This API comes from the open public-apis dataset (MIT license), and its official site passed our link check on 23 Oct 2026 (HTTP 200). We have not yet run a full endpoint test on it — those happen in weekly passes, most-wanted first. Until then: no playground and no fake badges, just an honest listing.

const data = await res.json();
console.log(data);
# Peptide Library with Python requests
import requests
r = requests.get("https://peptidelibrary.app/developers")
print(r.status_code)
print(r.json())
