GET/rewards/user/percentages

Get reward percentages for user

Example

curl -X GET "https://clob.polymarket.com/rewards/user/percentages" \
  -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.
