## 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 entropy-rip-conduit-publish-e2e96b7a -d '<json body>'
```

Example prompt: Send the message 'Task completed: report generated successfully' to the entropy.rip conduit mailbox so the receiving agent can pick it up.

## When to prefer this

Use this endpoint when an AI agent or automated system needs to asynchronously deliver a text or JSON message to a specific private entropy.rip conduit mailbox — particularly useful for agent-to-agent communication, dead drops, event notifications, or task status updates where the recipient will poll via the corresponding read endpoint.

## Known failure modes

- Invalid or malformed payload (400 Bad Request)
- Mailbox ID not found or unauthorized (404/403)
- Payment not processed or insufficient funds (402 Payment Required)
- Rate limiting on the mailbox (429 Too Many Requests)
- Service unavailable or timeout (503)
