Messari uses conventional HTTP response codes to indicate the success or failure of an API request. In general:
  • Codes in the 2xx range indicate success
  • Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, an entity was not found, etc.)
  • Codes in the 5xx range indicate an error with Messari’s servers (these are rare)
