GET/auth/ban-status/closed-only

Get closed-only mode status

Retrieves the closed-only trading mode status for the authenticated user. When closed-only mode is enabled, the user can only close existing positions and cannot open new ones.

Base URL: https://clob.polymarket.com
Auth: L2 API credentials (key, secret, passphrase)POLY_API_KEY, POLY_ADDRESS, POLY_SIGNATURE, POLY_PASSPHRASE, POLY_TIMESTAMP
Rate limit: 9,000 req / 10s (900 per second)
Limit applies to: CLOB API general

Example

curl -X GET "https://clob.polymarket.com/auth/ban-status/closed-only" \
  -H "POLY_API_KEY: $POLY_API_KEY" \
  -H "POLY_ADDRESS: $POLY_ADDRESS" \
  -H "POLY_SIGNATURE: $POLY_SIGNATURE" \
  -H "POLY_PASSPHRASE: $POLY_PASSPHRASE" \
  -H "POLY_TIMESTAMP: $POLY_TIMESTAMP"

L2 requests are signed with HMAC-SHA256 using your API secret, and the timestamp is part of the signature, so keep the machine's clock accurate. A missing credential or a stale signature both come back as Unauthorized/Invalid api key. The Python SDK signs for you.
