How this service works
Squares a knight, bishop, rook, queen, king or pawn reaches from a square on an empty board, with the count.
Output
Returns a list of algebraic notation square names (e.g. ['c6','e6','f5','f3','e2','c2','b3','b5']) that the specified piece can reach from the given starting square on an empty board, plus a count of those squares, a summary string, and metadata fields including source square, timestamp, and optional disclaimer.
Example use cases
Knight mobility analysis from center
“Show me all the squares a knight can reach from e4 on an empty board and tell me how many there are.”
Pawn move options for black
“What squares can a black pawn reach starting from d5 on an empty board?”
Queen coverage from corner square
“List every square a queen can move to from a1 on an empty board, with the total count.”
Technical details
Endpoint
GEThttps://chess-notation.x402tookit.com/piece-moves?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically determine the theoretical reach or mobility of a single chess piece from any board square on an empty board. Ideal for chess tutoring tools, puzzle generators, engine analysis helpers, or educational apps that need to explain piece movement rules. Prefer this over a full chess engine when you only need static piece mobility without considering other pieces or game state.
Side effects
- Invalid piece name returns an error or empty result
- Invalid square notation (e.g. 'z9') returns an error
- Missing required query parameters (piece or square) returns a 400-level error
- Color parameter ignored for non-pawn pieces
- Network or service unavailability returns a 402 or 5xx error
