# Fraction Simplifier – Reduce to Lowest Terms

> Fraction Simplifier – Reduce to Lowest Terms is a paid API for AI agents from fraction.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Reduces a fraction (numerator/denominator) to its lowest terms and returns its sign, integer status, and mixed-number form if improper.

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 fraction-simplifier-reduce-to-lowest-terms-5d142f9f -d '<json body>'
```

Example prompt: Can you simplify the fraction 36 over 48 to its lowest terms and tell me if it forms a mixed number?

## When to prefer this

Use this endpoint when you need exact, fully-reduced fraction arithmetic including sign normalization and mixed-number decomposition, especially in educational, financial, or symbolic math contexts where floating-point approximations are unacceptable.

## Known failure modes

- Zero denominator returns HTTP 400 with a descriptive error
- Non-integer inputs are rejected at schema validation
- Missing numerator field causes a 400 validation error
- Extremely large integers may exceed server limits

## How this service works

Reduce a fraction to lowest terms and describe it: numerator/denominator (denominator normalized positive), sign, whether it is an integer, and a mixed-number form when improper. A zero denominator is a clean 400.

## Output

Returns the fraction reduced to lowest terms with a positive denominator, along with the sign of the result, a boolean indicating whether the result is a whole integer, and a mixed-number representation (whole part plus proper fraction) if the original was improper. A zero denominator returns a clean 400 error.
