REST API for Delphi project & Windows server deployment

Task Description

Create an intermediate REST API application in Delphi that will provide access to the functions of an existing library (DLL) written in Delphi and running in a Windows environment. This API will allow a Linux bot written in Python to send data for processing and receive results via HTTP requests.

REST API Functionality

• Implement the API with the ability to:
  • Receive HTTP requests (POST/GET).
  • Process parameters passed in the requests (for example, game coefficients).
  • Return processing results in JSON format.
• Ensure the processing of multiple functions from the Delphi library (DLL), each of which will be available through a separate endpoint.

API Technical Details

• Use a library to implement the HTTP server (for example, Indy, Synapse, or others supported by Delphi).
• Support the following HTTP methods:
  • POST: Sending data for processing (for example, coefficients).
  • GET: Retrieving the current status of the API or the last processing result (optional).

Logging and Error Handling

• Log all incoming requests and processing results to a file.
• Handle exceptions: if an error occurs in the DLL or incorrect data is passed, return a clear error message to the client.

Deployment

• Script/instructions for running the REST API on a Windows machine.
• Ensure that the API starts automatically when the system boots (can be done via a Windows service).

Provided Resources

• DLL library with a description of exported functions.
• Test sample data for processing (input coefficients from the Linux bot received via the API).

Candidate Requirements

• Experience with Delphi and libraries for creating HTTP servers (Indy/Synapse).
• Knowledge of working with DLLs and exported functions.
• Ability to document the API and write structured code.

Provide your proposals regarding deadlines and cost of work.

I will provide a desktop project example in a private chat.

If anything is unclear or additional information is required, I am always available.
