## 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 rum-bottle-sort-hint-undo-pack-x5-39d125e5

Example prompt: I'm stuck on Rum Bottle Sort — can you buy me a pack of 5 hints and undos for 1 USDC so I can keep playing?

## When to prefer this

Choose this endpoint when a user is playing Rum Bottle Sort and wants to purchase a batch of 5 hints/undos in a single 1 USDC micropayment via the x402 protocol on Base. It is specifically scoped to the Rum Bottle Sort game's hint/undo mechanic, distinct from coin packs, tips, or continue packs. Prefer this over manual in-app purchases when operating an AI agent with a Base wallet capable of x402 payments.

## Known failure modes

- Insufficient USDC balance on Base wallet — payment rejected
- x402 payment protocol handshake failure — endpoint returns 402 with payment details but agent fails to complete payment
- Network timeout on Base blockchain confirmation — transaction may be pending
- Duplicate redemption attempt — server may reject replayed requests
- Invalid or missing x402 payment header — returns 400 or 402 error
