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 rengi-forge-leaderboard-board-creator-bbe98310 -d '<json body>'
```

Example prompt: Create a leaderboard called 'Space Blaster High Scores' that sorts descending (higher is better), tracks all-time and daily scores, and requires HMAC-signed submissions — give me the keys and the JS snippet to embed.

## When to prefer this

Choose this endpoint when you need a managed, hosted leaderboard backend for a game without building your own database and score API. It is especially valuable when you want an instant JS embed snippet (zero backend code for web games), need HMAC-signed submission enforcement for anti-cheat, or want multi-period (alltime/daily/weekly) scoring out of the box. Prefer this over self-hosted solutions when speed of integration matters and you're building on rengi.dev's game tooling ecosystem.

## Known failure modes

- Invalid or missing board name (minLength 1, maxLength 80 violated)
- Invalid sort enum value (must be 'asc' or 'desc')
- Invalid periods array item (must be 'alltime', 'daily', or 'weekly')
- Periods array length outside bounds (minItems 1, maxItems 3)
- Payment failure or insufficient USDC funds ($1 required via x402)
- minScore greater than maxScore causing invalid score range

## How this service works

Leaderboard: Create a board with 100,000 submissions and 365 days; returns keys and a ready JS snippet. Full schema: https://rengi.dev/v1/leaderboard/schema

## Output

Returns board keys (used to submit and read scores) and a ready-to-embed JavaScript snippet that can be dropped directly into a web game or app to interact with the leaderboard, scoped to the configured name, sort order, periods, and score bounds.
