HTTP Response codes

The koinju API returns HTTP status codes in addition to JSON-based error codes and messages.

The koinju REST API attempts to return conventional HTTP status codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Status codes in the 4xx range indicate a failed request based on client information or context (for exemple, wrong parameter or a rate limit...). Status code in the 5xx range indicate an error from the koinju's servers.
HTTP Success
Successful HTTP responses have the status code 200 like in this exemple :
200 : Success 
{
  "api_version": "2.0.0",
  "server_time": "2020-02-25T15:48:26.538Z"
}
HTTP Errors
All HTTP requests with response status codes different to 200 must be considered as failed and you should expect additional JSON inside the body of the response with the error message encapsulated inside it as shown in the example :
 500 : Internal Error 
{
  "status_code": 500,
  "message": "Internal server error. Please contact the support if the problem persists."
}
 We use the following error codes:
Code
Message
Description
200
OK
Success!
400
Bad Request
The request was unacceptable, often due to missing a required parameter. Please check the accompanying error message for further details. 
401
Unauthorized
Missing or incorrect authentication credentials.
403
Forbidden
The request is fine but you doesn't have permissions to perform the request, you naughty boy.
404
Not Found
The requested ressource does not exist. Make sure there is no trailing / at the end of any endpoint.
429

Returned when a request cannot be served due to the rate limit. Too many requests hit koinju too quickly.
500
Internal Server Error

502
