# Errors

ChainVine uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success, whereas codes in the 4xx range indicate an error caused by invalid request information, and codes in the 5xx range indicate an error with ChainVine’s servers.
