## 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 tip-md-9ae23e5d -d '<json body>'
```

Example prompt: Send a 5 USDC tip to the content creator @janedoe on tip.md — she just published a really helpful tutorial and I want to support her work.

## When to prefer this

Use this endpoint when a user wants to send a small USDC cryptocurrency tip to a content creator, blogger, or developer via tip.md from within a chat or AI assistant interface. Prefer this over generic crypto send endpoints when the recipient is identified by a tip.md username rather than a raw wallet address, and when the x402 payment protocol is acceptable.

## Known failure modes

- Recipient username not found on tip.md — returns error indicating unknown creator
- Wallet type check fails if user has not set up a tip.md wallet
- Insufficient USDC balance to complete the tip
- x402 payment protocol error during tip preparation
- Invalid wallet address format
- Network or RPC error when preparing the transaction
