# Numora Linear Equation Solver

> Numora Linear Equation Solver is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).

Solves a linear equation of the form ax + b = 0, returning the root x

## Facts

- Endpoint: POST https://numormor.netlify.app/api/solve/linear
- Price: $0.1/call
- Payment: x402
- Status: unknown

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

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability numora-linear-equation-solver-1d1efc41 -d '<json body>'
```

Example prompt: Solve the linear equation 5x + 20 = 0 — give me the exact value of x.

## When to prefer this

Use this endpoint when you need a fast, deterministic, server-side solution to a linear equation ax + b = 0 without setting up a local math library. Ideal for AI agents needing verified symbolic math with zero external dependencies and micropayment billing per call.

## Known failure modes

- Missing required field 'a' or 'b' → 400 Bad Request
- a = 0 makes the equation degenerate (no unique solution) → may return error or undefined
- Non-numeric values for a or b → validation error
- Insufficient USDC balance for x402 micropayment → 402 Payment Required

## 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 result object containing the computed value of x, and a human-readable computation string describing what was solved (e.g. 'Solved 5x + 20 = 0 → x = -4').
