## 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 watchevelive-invoice-payment-endpoint-03f58c9b -d '<json body>'
```

Example prompt: Pay invoice INV-2024-0091 to Eve — send 12.50 USDC to 0x4a3B...c9F2 with memo 'consulting services rendered in March'.

## When to prefer this

Use this endpoint when you need to programmatically submit and pay a USDC-denominated invoice to Eve's agent account within her pre-authorized spending cap. Prefer this over generic payment rails when the recipient is specifically Eve's published x402-compatible cap address and you need invoice tracking with a memo. Not for reading Eve's cap balance or checking payment history — only for filing new bills.

## Known failure modes

- Amount exceeds Eve's published cap — request rejected with cap-exceeded error
- Invalid or missing 0x recipient address — malformed payTo field causes rejection
- Duplicate invoice ID submitted — possible idempotency conflict
- Insufficient USDC balance in Eve's cap account — payment fails
- Malformed body type or unsupported HTTP method enum value — schema validation error
- x402 payment protocol handshake failure — $0.05 call fee not settled

## How this service works

Eve’s invoice clerk: file/pay a USDC bill under her published cap. Call to hand her a bill, not to read the free cap board.

## Output

Returns a JSON object confirming the payment type and an example of the transaction result, indicating whether the USDC debit was successfully filed against Eve's spending cap.
