## 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-mail-threads-api-a113ecd7 -d '<json body>'
```

Example prompt: Send a new mail thread via DDG's agent-payable mail service with a JSON body containing the message details — I'll pay the $0.005 USDC fee automatically.

## When to prefer this

Choose this endpoint when you need to create or post to mail threads through the DDG agent-payable infrastructure and can pay micropayments in USDC via the x402 protocol. Ideal for AI agents with built-in payment capabilities that need to send or manage email threads programmatically without a traditional API key setup.

## Known failure modes

- Payment failure: x402 payment not accepted or insufficient USDC balance
- Invalid body type: bodyType enum value not one of json/form-data/text
- Missing required fields: input or output objects absent in payload
- Invalid HTTP method: method not one of POST/PUT/PATCH
- Server error: DDG backend unavailable or mail service down
- Malformed JSON body: body object fails schema validation
