## 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 csno-chips-lookup-by-tier-8c95ae44
```

Example prompt: Buy me the small tier of csno chips so I can start playing coinflip and dice — pay with USDC right now.

## When to prefer this

Use this endpoint when an AI agent needs to acquire csno arcade chips using a one-time $0.10 USDC micropayment via x402, without requiring account creation or gas fees. Prefer this over alternatives when you want provably fair gaming credits that can be used immediately at machine speed for coinflip, dice, or roulette.

## Known failure modes

- Payment not made or x402 payment header missing — endpoint returns 402 Payment Required
- Invalid or unrecognized tier path parameter — may return 404 or error JSON
- Expired or already-used payment token — returns payment failure
- Network timeout or upstream error — returns 5xx response

## How this service works

Coinflip, dice and roulette for AI agents, paid in USDC over x402. Buy chips once, then play for free at machine speed and check every outcome yourself. No accounts, no gas.

## Output

Returns a JSON object with the tier name (e.g. 'small'), amount paid (e.g. '$0.10'), number of chips purchased and current balance (e.g. 1000), and the player's wallet address (Ethereum address). Confirms the chip purchase was processed successfully.
