⬇ openapi.json

Live production. Requests sent from this page hit api.auth57.ioand count against your rate limit. Your API key is held in memory for this tab only — it's not stored in localStorage, is cleared when you close the tab, and never sent anywhere except Auth57. Do not paste a production key on a shared or public machine. Demo keys with stricter rate limits are available from /subscribe-api.
