## Services

- [Matrix Determinant Calculator](https://www.zero.xyz/c/matrix-determinant-calculator-07066ec1/llms.txt): $0.004/call via x402. Computes the determinant of a square matrix using Gaussian elimination with partial pivoting
- [Matrix Linear System Solver (Ax=b)](https://www.zero.xyz/c/matrix-linear-system-solver-ax-b-8a18f58f/llms.txt): $0.004/call via x402. Solves a square linear system A·x = b using Gaussian elimination with partial pivoting, returning the solution vector or a solvable:false flag for singular systems.
- [Matrix Inverse via Gauss-Jordan Elimination](https://www.zero.xyz/c/matrix-inverse-via-gauss-jordan-elimination-ad7cd03d/llms.txt): $0.004/call via x402. Computes the inverse of a square matrix using Gauss-Jordan elimination, returning the inverse matrix or indicating non-invertibility if the matrix is singular.
- [Matrix Multiplication API](https://www.zero.xyz/c/matrix-multiplication-api-a346888a/llms.txt): $0.004/call via x402. Multiplies two matrices A and B (A·B), requiring compatible inner dimensions, and returns the resulting product matrix.
- [Matrix Transpose](https://www.zero.xyz/c/matrix-transpose-c13ed251/llms.txt): $0.004/call via x402. Transposes an m×n matrix by swapping its rows and columns, returning the n×m result.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.
