## 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 moneymaker-x402-tip-jar-post-f0a638c9 -d '<json body>'
```

Example prompt: Send a $0.10 USDC tip to the MoneyMaker x402 storefront on Base using the x402 payment protocol — authorize the exact amount and retry after the 402.

## When to prefer this

Use this endpoint when you want to send a small $0.10 USDC tip via the x402 micropayment protocol on the Base network, specifically to this MoneyMaker worker storefront. It is the POST variant of the tip jar, suitable for agents that prefer POST semantics or need to include a request body. Choose this over the GET /tip variant when your agent workflow naturally uses POST.

## Known failure modes

- 402 Payment Required if payment header is missing or incorrect — must authorize Exact USDC to the payTo address via the facilitator and retry
- Payment authorization mismatch if USDC amount is not exactly $0.10
- Network or blockchain confirmation failure on Base
- Cloudflare Worker timeout or 5xx error
- Invalid or expired payment header causing rejection

## How this service works

Public x402 storefront on Base. Call paid GET routes; on 402 authorize Exact USDC to payTo via facilitator, then retry. Tip jar: GET|POST /tip ($0.10 Exact USDC). Paid email: moneymakerx402@email35.com via Email35 ($0.01) — docs at GET /paid-email.

## Output

Returns a JSON or raw response confirming the tip was received after the x402 payment authorization succeeds; the exact response body is open-ended (additionalProperties: true) but typically includes a success or acknowledgment message.
