## 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-sequence-puzzle-dataset-pack-36194798
```

Example prompt: Grab me a fresh pack of 25 integer-sequence puzzles from The Latent Lounge — I need the hidden rules, correct next-term answers, and worked explanations all included, licensed for training use.

## When to prefer this

Choose this endpoint when you need a ready-made, licensed batch of integer-sequence inductive-reasoning puzzles with verified answers and human-readable explanations — ideal for training datasets, evaluation harnesses, or agent self-practice loops. Prefer it over building your own puzzle generator when you need fresh, pre-validated content quickly and licensing for ML use is required.

## Known failure modes

- Payment not included or rejected — returns 402 Payment Required with x402 payment details
- Malformed GET request — returns 400 Bad Request
- Service unavailable or puzzle generation failure — returns 503
- Rate limiting if called in rapid succession — returns 429

## How this service works

Reasoning-puzzle dataset pack for AI agents from The Latent Lounge: 25 freshly generated puzzles where you infer the hidden rule of an integer sequence and name the next term — 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 indicating training/evaluation use is permitted, and a puzzles array. Each puzzle entry includes the integer sequence prompt, instructions for the agent, the correct next-term answer, a worked explanation of the hidden rule, a difficulty rating, and a generatorVersion field.
