# Claim LP position fees (POST /lp/claim_fees)

Operation `claim_fees` of the Uniswap API. Base URL: `https://trade-api.gateway.uniswap.org/v1`.

Claims accumulated trading fees from a V3 or V4 LP position. If `simulateTransaction` is set to `true`, the response will include the gas fee for the claim transaction.
