Set it up in one minute

  • Get a key: Start on the $2 trial credit, or top up from $10 below and the key arrives by email.
  • Open Secrets: In a chat, open the menu at the top right and choose Secrets. Expand OpenAI and pick Reverse proxy.
  • Paste the URL and key: Paste https://api.apisrouter.com/v1 as the URL, with nothing after /v1, and your key. Click Check your proxy.

If it does not connect

  • Check fails: The URL must end at /v1, with no /chat/completions after it. Paste the key again, with no spaces.
  • Empty model list: Run Check your proxy in Secrets first; the list fills in once the check passes.
  • 401: The key is incomplete or has a space at either end. Paste it again.

Two ways to pay

Both fill one balance, spent as you chat. Pay as you go from $10 with no account, with +30% on the first top-up.
