Exchange REST API Requests

All requests and responses are application/json content type and follow typical HTTP response status codes for success and failure.

Note: Request URLs must be lowercase as URLs are case-sensitive.

Errors

{
  "message": "Invalid Price"
}

Unless otherwise stated, errors to bad requests respond with HTTP 4xx or status codes. The body also contains a message parameter indicating the cause. Your language’s http library should be configured to provide message bodies for non-2xx requests so that you can read the message field from the body.

Common Error Codes

Status Code	Reason
400	Bad Request — Invalid request format
401	Unauthorized — Invalid API Key
403	Forbidden — You do not have access to the requested resource
404	Not Found
500	Internal Server Error — We had a problem with our server

Success

A successful response is indicated by HTTP status code 200 and may contain an optional body. If the response has a body it is documented under each resource below.
