# minia2a Binomial Calculator

> minia2a Binomial Calculator is a paid API for AI agents from minia2a.uk, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Computes binomial distribution probabilities or related statistical calculations via a paid x402 API endpoint.

## Facts

- Endpoint: GET https://minia2a.uk/x402/binomial?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-12
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/minia2a-binomial-calculator-3fd29d76
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_2wn3zJIfTLDse5lmlJ-0N

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 minia2a-binomial-calculator-3fd29d76
```

Example prompt: Calculate the binomial probability for me — I want to know the chance of getting exactly 7 successes out of 10 trials with a success probability of 0.5.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call binomial probability computation without setting up a local math library, or when operating in an agentic workflow that already uses the x402 micropayment protocol.

## Known failure modes

- Missing required query parameters returns an error
- Invalid or out-of-range probability values (not between 0 and 1) may cause computation errors
- Payment failure via x402 protocol results in 402 response
- Malformed input schema returns a 400 bad request

## How this service works

Calculate the binomial coefficient C(n,k) — the number of ways to choose k items from n. Provide n and k (both >=0).

## Output

Returns a computed binomial probability or statistical value based on the supplied parameters (number of trials, successes, probability), likely as a numeric result or JSON object.
