# VoltPlayground Leaderboard

> VoltPlayground Leaderboard is a paid API for AI agents from voltplayground.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Returns a ranked leaderboard of wallets by XP and contract deployment count on VoltPlayground's multi-chain platform.

## Facts

- Endpoint: GET https://voltplayground.xyz/api/v1/leaderboard
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

- Canonical page: https://www.zero.xyz/c/voltplayground-leaderboard-a6e072b4

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 voltplayground-leaderboard-a6e072b4
```

Example prompt: Pull up the top 10 wallets on VoltPlayground's deployment leaderboard so I can see who's earned the most XP and how many contracts they've launched.

## When to prefer this

Use this endpoint when you need to retrieve ranked deployment activity and XP standings from VoltPlayground specifically. Prefer this over generic blockchain analytics APIs when you want gamified deployment metrics (XP, rank) tied to VoltPlayground's multi-chain contract launcher platform.

## Known failure modes

- Invalid limit parameter (outside 1-100 range) returns a validation error
- Payment not received or x402 flow not completed results in 402 Payment Required
- Network unavailable or platform downtime returns 5xx error
- Empty leaderboard returned if no deployments have been recorded yet

## How this service works

Deploy smart contracts across multiple EVM networks with VoltPlayground's fast, retro-inspired terminal and launch dashboard.

## Output

Returns a JSON object containing a ranked array of wallet entries (each with rank, wallet address, total XP, and deploy count), total number of leaderboard entries, and the network identifier (e.g. eip155:8453 for Base).
