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 omniapi-fraction-math-tool-4c52951c -d '<json body>'
```

Example prompt: Can you calculate 3/4 plus 5/6 and simplify the result to its lowest terms?

## When to prefer this

Choose this endpoint when you need programmatic, on-demand fraction arithmetic — such as simplification, addition, subtraction, multiplication, or division of fractions — and want to pay per call in USDC without a subscription. Useful in agentic workflows that need reliable math computation without embedding a local math library.

## Known failure modes

- Invalid or unparseable fraction expression returns an error response
- Division by zero in denominator causes computation failure
- Malformed query string results in a 400-level error
- Network or payment authorization failure via x402 returns 402 Payment Required
- Ambiguous or unsupported operation type may return a generic error

## How this service works

444 endpoints across 9+ chains. Crypto, AI, Social, Finance, Weather, Tools. Pay per call in USDC via x402 with 4 facilitators: Dexter, Meridian, FluxA, GoPlausible.

## Output

Returns the result of the requested fraction operation, typically including the simplified fraction, possible decimal representation, and intermediate steps such as common denominators or reduced forms.
