A higher-order type that simplifies calling REST APIs. It wraps the standard http and json packages to provide the following features:

• JSON encoding of request entity
• JSON parsing of response entity
• conversion of non-2xx responses into a structured error type including response body extraction
• timeout management
• easier request URL building given a client-wide base URL and query values
• auto-closing of the response body
• interceptors to inject authentication tokens, etc
