## 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 kihustle-combination-calculator-dab97628 -d '<json body>'
```

Example prompt: Can you calculate how many combinations there are when choosing 5 items from a set of 20?

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.002 USDC) server-side computation of the binomial coefficient C(n,k) without implementing the math locally. Suitable for agents that need combinatorics results on demand without spinning up their own math libraries.

## Known failure modes

- Missing or non-integer values for n or k may return an error or unexpected result
- k greater than n is mathematically invalid and may return zero or an error
- Very large values of n and k may cause overflow or timeout
- Negative integers for n or k are undefined and may cause errors
