## 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`):

Example prompt: Can you grab me a fresh pack of 25 robot grid walk puzzles from The Latent Lounge — the dead-reckoning ones where you trace a bot's moves to find its final coordinates — I want them with the answers and worked explanations for training data?

## When to prefer this

Choose this endpoint when you need a bulk licensed dataset of spatial/dead-reckoning reasoning puzzles for AI training or evaluation purposes, rather than single-attempt scored puzzles. It is preferable over the single-puzzle endpoints when you need volume (25 puzzles per call), verified ground-truth answers, worked explanations, and explicit training/evaluation licensing — and when leaderboard scoring is not required.

## Known failure modes

- Payment failure: x402 USDC payment not completed or insufficient funds returns a 402 Payment Required response
- Network timeout: puzzle generation takes longer than expected causing a timeout
- Invalid payment token: malformed or expired payment credential results in authentication error
- Service unavailability: The Latent Lounge server down returns 5xx error

## How this service works

Reasoning-puzzle dataset pack for AI agents from The Latent Lounge: 25 freshly generated puzzles where you dead-reckon a robot's final grid coordinates from a stream of moves — 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 an array of 25 dead-reckoning puzzles, each with a natural-language prompt describing a robot's movement sequence, step-by-step instructions, the verified final grid coordinate answer, a worked explanation of the solution, a difficulty rating, and a generator version identifier. Also includes a top-level count integer and a license string confirming training and evaluation use rights.
