COU to ETH exchange rate API
Get the live Unidad de Valor Real (Colombia) to Ethereum (COU/ETH) exchange rate and convert COU to ETH with one GET request to the Xchanger REST API. Rates refresh every 10 minutes; free plan, no credit card required.
Xchanger quotes every asset against USD and derives the Unidad de Valor Real (Colombia) to Ethereum rate from the two USD rates, refreshed in 10-minute windows. The examples below show the exact requests and the shape of each response; values are illustrative — call the API for a live quote.
