x402
Numora LU Decomposition API is a paid API for AI agents from numormo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).
Performs LU decomposition on a matrix, factoring it into lower and upper triangular matrices for use in solving linear systems and related computations

How this service works
100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.
Output
Returns a JSON object with success=true, a human-readable computation description, and a result object containing the L (lower triangular) and U (upper triangular) matrices from the LU factorization, along with any permutation information used during partial pivoting.
Example use cases
Solving a system of linear equations
“I need to solve a system of linear equations. Can you do LU decomposition on this coefficient matrix [[2, 1, -1], [-3, -1, 2], [-2, 1, 2]] so I can use the L and U factors to find the solution?”
Engineering stiffness matrix factorization
“I have this stiffness matrix [[10, -2, 0], [-2, 8, -1], [0, -1, 5]] from a structural analysis problem — can you run LU decomposition on it so I can efficiently solve multiple load cases?”
Validating numerical stability of a matrix
“Can you LU-decompose this matrix [[1, 2, 3], [4, 5, 6], [7, 8, 10]] for me? I want to inspect the U factor to check if it's numerically well-conditioned before I use it in further calculations.”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/matrix/luWhen to prefer
Choose this endpoint when you need pure, dependency-free LU matrix factorization in an agent workflow without spinning up a numerical computing environment. Ideal for scenarios requiring repeated solves of Ax=b with different right-hand sides, inverting matrices, or computing determinants as intermediate steps. Prefer this over general-purpose compute endpoints when you need a lightweight, pay-per-call math API on Base with no setup overhead.
Side effects
- Non-square matrix provided — returns error since LU decomposition requires a square matrix
- Singular or near-singular matrix — may fail or return degenerate factors
- Malformed input (non-numeric values, jagged arrays) — returns validation error
- Empty matrix array — returns missing or invalid input error
- Payment failure via x402 — request not processed if USDC micropayment on Base is not completed
