Check Wallet Credentials
curl --request GET \

  --header 'Authorization: Bearer <token>'
{
  "hasCredentials": true,
  "walletAddress": "<string>",
  "signatureType": 123
}
Verify whether the specified wallet has a Polymarket CLOB credential record registered for the authenticated user. This is a prerequisite check before placing trades, but hasCredentials=true only confirms that Aion has a stored credential row for the current user and wallet. It does not revalidate the credential against Polymarket in real time. The stored signatureType (0=EOA, 1=POLY_PROXY, 2=GNOSIS_SAFE, 3=POLY_1271 / Deposit Wallet) identifies the wallet type. Only Polymarket Deposit Wallets need to be registered with signatureType=3 explicitly via POST /wallet/credentials; for other wallet types the backend auto-detects via on-chain getCode().
