OKX — read-only API key
Trading-type key with the Read permission only, plus a passphrase you choose. You create the key on okx.com; it takes a couple of minutes.
- You will end up with
- API key · Secret · Passphrase
Log in to okx.com.
Go to Account, then API.
Click Create API Key.
Select Trading as the API type.
Set a name and a passphrase.
Warning: You choose this passphrase and OKX will not show it again. Write it down — verification needs it alongside the key and secret.
Under permissions, select Read only.
Warning: Leave Trade and Withdraw unchecked. Read is all that verification needs.
Leave the IP whitelist empty.
Complete the verification.
Copy the API key, secret and passphrase.
Warning: The secret is displayed once and never again. Copy it before closing the dialog — if you lose it you have to delete the key and start over.
In Preuval: select OKX, set the environment to Production, and paste all three values.
Save the credentials somewhere safe
Copy each value into a password manager as the exchange shows it. Secrets are displayed once, and a half-copied secret fails authentication in a way that looks identical to a wrong one. Preuval never writes your keys to disk — they are used for the run and discarded.
