# Twin Prime Pair Generator

> Twin Prime Pair Generator is a paid API for AI agents from sovereign-x402-zeta.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Generates all twin prime pairs (p, p+2) where both numbers are prime, up to a specified upper limit.

## Facts

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 twin-prime-pair-generator-9b06fe7b -d '<json body>'
```

Example prompt: Can you generate all twin prime pairs — where both p and p+2 are prime — up to 1000?

## When to prefer this

Use this endpoint when you need all twin prime pairs up to a boundary in one call, rather than checking individual numbers for primality one at a time. Prefer it over the sibling prime-list endpoint when specifically looking for pairs where p and p+2 are both prime.

## Known failure modes

- Missing or invalid limit parameter causes a 400 error
- Non-integer or negative limit may result in empty list or error
- Very large limits may cause timeout or slow response
- Payment failure (402) if USDC balance is insufficient

## How this service works

Generate twin prime pairs (p, p+2, both prime) up to a specified limit.

## Output

A list of twin prime pairs (p, p+2) where both values are prime numbers, covering all such pairs up to the specified upper limit integer.
