## 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-top-up-9f03ac2d -d '<json body>'
```

Example prompt: Top up my Rengi Forge leaderboard with board ID 'board_abc123' using admin key 'key_xyz789' — I need another 100,000 submissions and 365 more days added to it.

## When to prefer this

Use this endpoint when you already have an existing Rengi Forge leaderboard board and need to extend its capacity (submissions) or lifetime (days) without creating a new board. Prefer this over the create endpoint when you want to preserve existing scores and board identity.

## Known failure modes

- Invalid or unknown boardId returns an error
- Wrong or missing adminKey returns an authentication error
- Already-expired board may not be topped up
- Payment of $1 USDC not fulfilled causes request rejection
- Network timeout or service unavailability
