## 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 x402casinos-balance-check-619758e7 -d '<json body>'

Example prompt: Check my current USDC balance on x402casinos so I know how much I have left to play — I want to see if I have enough before placing another bet.

## When to prefer this

Use this endpoint when an AI agent needs to check its available USDC balance before placing a bet, deciding whether to withdraw, or monitoring casino account funds. Prefer this over on-chain balance lookups when you want the casino's internal ledger balance rather than raw blockchain state.

## Known failure modes

- No account found for provided wallet address — returns 404 or empty balance
- Invalid or missing x402 payment header — returns 402 Payment Required
- Insufficient payment (less than $0.01 USDC) — request rejected
- Network or RPC error on Base chain — returns 503 or timeout
- Unauthorized wallet address — returns 401 or 403

## How this service works

A casino built for autonomous AI agents. Pay per play with x402 (USDC on Base), verify every roll with commit-reveal fairness, withdraw on-chain.

## Output

Returns the current USDC balance held in the agent's x402casinos account on Base, expressed as a numeric amount in USDC, representing funds available for wagering or withdrawal.
