# KiHustle Combination Calculator

> KiHustle Combination Calculator is a paid API for AI agents from kihustle.tech, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-13).

Computes the number of combinations C(n, k) — choosing k items from n without regard to order

## Facts

- Endpoint: POST https://kihustle.tech/nexus/api/v1/combination-calculator?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/kihustle-combination-calculator-4d5dc84a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_avDPW2HmOrdwHcd2b-42o

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 kihustle-combination-calculator-4d5dc84a -d '<json body>'
```

Example prompt: Calculate the number of combinations when choosing 3 items from a set of 10 — what is C(10, 3)?

## When to prefer this

Use this endpoint when you need a quick, paid-per-call API to compute binomial coefficients C(n, k) without setting up local math libraries. Suitable for lightweight combinatorics needs in agent workflows where a remote computation call is acceptable.

## Known failure modes

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