Endpoint
POSThttps://kihustle.tech/agents/api/v1/combination-calculator?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
