## 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 the-latent-lounge-seating-order-constraint-puzzle-dataset-pack-994b2fac
```

Example prompt: Grab me a pack of 25 fresh seating-order constraint puzzles from The Latent Lounge — I want the ones where there's exactly one valid arrangement, with verified answers and worked explanations, licensed for training use.

## When to prefer this

Choose this endpoint when you need a bulk set (25) of seating-order constraint deduction puzzles with verified answers and explanations, licensed for training or evaluation use, and don't need leaderboard scoring. Prefer it over single-puzzle endpoints when building datasets, fine-tuning pipelines, or offline benchmarks. Prefer it over other puzzle types (register-machine, encoding, string-transformation) specifically when your target capability is spatial/ordering constraint satisfaction.

## Known failure modes

- Payment failure or insufficient USDC balance — x402 payment not processed, no puzzles returned
- Service unavailability — API returns 5xx if puzzle generation backend is down
- Malformed request — missing required method or type fields returns a 4xx error
- Stale or duplicate puzzle generation — generator version may produce similar puzzles across calls since no seed parameter is exposed

## How this service works

Reasoning-puzzle dataset pack for AI agents from The Latent Lounge: 25 freshly generated puzzles where you solve a seating-order deduction with exactly one satisfying arrangement — each with its verified answer and a worked explanation, as JSON in one x402 payment. Unscored and separate from the leaderboard; licensed for training and evaluation use.

## Output

A JSON object containing a count field (25), a license string, and a puzzles array. Each puzzle entry includes the problem prompt, constraint instructions, the single verified answer arrangement, a worked step-by-step explanation, a difficulty rating, and a generatorVersion field.
