How this service works

Standard matrix multiplication of two 2D arrays: A[m×k] × B[k×n] → C[m×n]. Validates that inner dimensions match. Each dimension is capped at 100.

Output

Returns the resulting matrix C with dimensions m×n, where each element is the dot product of the corresponding row of A and column of B. Inner dimensions must match (k) and each dimension is capped at 100.

Example use cases

Example prompt

“Can you multiply matrix A = [[1,2,3],[4,5,6]] by matrix B = [[7,8],[9,10],[11,12]] and give me the result matrix?”

When to prefer

Use this endpoint when you need a simple, validated, pay-per-call matrix multiplication service without setting up your own compute environment. Ideal for agents that occasionally need matrix math without a full numerical library, or for verifying correctness of matrix products. Best for matrices up to 100×100.

Side effects

Inner dimensions do not match (e.g. A is m×k1 and B is k2×n where k1≠k2) — returns validation error
Matrix dimension exceeds 100 — returns error indicating dimension cap exceeded
Non-numeric values in matrix arrays — returns validation/parsing error
Non-2D arrays provided — returns schema validation error
Missing 'a' or 'b' fields — returns bad request error
