## 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 ddg-agent-payable-mail-send-a34962da -d '<json body>'
```

Example prompt: Send an email to john.doe@example.com with the subject 'Project Update' and body 'Hi John, just wanted to let you know the report is ready for review. Thanks!' — use the DDG agent-payable mail service and charge the $0.005 USDC fee via x402.

## When to prefer this

Choose this endpoint when your AI agent needs to send email messages in an automated, machine-payable workflow using x402 crypto micropayments ($0.005 USDC per send), especially when operating without traditional API key authentication and needing a lightweight pay-per-use email delivery option compatible with agentic payment rails.

## Known failure modes

- Insufficient USDC balance or x402 payment failure resulting in 402 Payment Required
- Invalid or malformed email body JSON resulting in 400 Bad Request
- Missing required fields (type, method, bodyType, body) causing schema validation error
- Recipient address unreachable or invalid causing delivery failure
- Service unavailability returning 5xx errors
