# minia2a Amicable Pair Finder

> minia2a Amicable Pair Finder is a paid API for AI agents from minia2a.uk, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Given a number, finds its amicable pair — the other number in an amicable pair where each number equals the sum of the proper divisors of the other.

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-amicable-pair-finder-3f63571c
```

Example prompt: Can you find the amicable pair for the number 220? I want to know which number forms an amicable pair with it based on their proper divisors.

## When to prefer this

Choose this endpoint when you need a quick, paid, on-demand computation of amicable pairs for number theory tasks, math puzzles, or educational tools, and don't want to run the computation locally. It's a lightweight API that handles the divisor-sum logic for you without requiring a math library.

## Known failure modes

- Input number has no amicable pair (perfect numbers or non-amicable integers) — returns null or error
- Non-integer or negative input causes validation failure
- Very large numbers may time out or exceed computation limits
- Missing required input parameter returns a schema validation error

## How this service works

minia2a service: x402-amicable-pair

## Output

Returns the amicable partner number for the given input — i.e., the number whose proper divisors sum to the input, and whose input's proper divisors also sum back to it. May also indicate if no amicable pair exists for the given number.
