tic tac toe api

• This API is used by my tic tac toe react app game
• API is available here https://tic-tac-toe-api-356923.ue.r.appspot.com/
• It has one endpoint POST /api/get-move -
• payload: { board: 3 x 3 array of X's and O's, player: the player whose move you want to get, difficulty: the difficulty level of the AI, 1-easy,2-medium,3-hard,4-impossible }
• payload example: { "board": [ [ "", "X", "" ], [ "", "O", "" ], [ "", "", "X" ] ], "difficulty": 4, "player": "O" }
• example response: {"data": {"position": 6, "coordinates": [1, 2]}}
• position is the position of the move in a board numbered like this [[1,2,3],[4,5,6],[7,8,9]] and the coordinates are the row and column (zero-indexed) in a 3x3 array. Note that position and coordinates communicate the same information in different formats

Implementation Details

• Easy, Medium, and Impossible difficulties are all based on variations of the minimax algorithm
• Hard mode is using OpenAI's GPT-3 which was trained on data from impossible mode
