## 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-comms-proof-endpoint-226fc0b8 -d '<json body>'
```

Example prompt: Submit a communication proof request to DDG agent services with a JSON POST body containing my message data, and pay for it using the x402 USDC payment rail.

## When to prefer this

Choose this endpoint when you need to submit a verifiable communication proof through DDG's agent-payable infrastructure using the x402 protocol with USDC micropayments, particularly when your agent workflow requires an auditable record of a machine-initiated HTTP communication.

## Known failure modes

- Payment not processed — x402 payment header missing or insufficient USDC balance
- Invalid input type — must be 'http' const string
- Unsupported HTTP method in body — only POST, PUT, PATCH accepted
- Invalid bodyType enum — must be json, form-data, or text
- Missing required fields (input or output objects) causing schema validation failure
- Service unavailable on agents.daedalusdevelopmentgroup.com
