Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

## When to prefer this

Use this endpoint when you specifically want to reach Thomas Marchand (th0rgal) — a human individual — to discuss collaboration, commission work, or ask a concrete question. This is not a general-purpose messaging or email API; it is a direct, paid human-to-human contact channel with a specific person. Prefer this over generic email APIs when the target recipient is explicitly Thomas Marchand and you want a lightweight, pay-per-contact model.

## Known failure modes

- Missing or malformed callback_url results in no reply channel
- No contact_hint and no callback_url means Thomas cannot reach you back
- Invalid refund_to address causes postage refund to fail
- Overly vague message may not elicit a useful response
- HTTP 402 payment required if USDC payment is not attached
