DimeBox Gives AI Agents a Pay-Per-Call Mailbox

Field notes
DimeBox exposes email operations as paid HTTP requests: an agent can submit a brief for Claude-generated mail or provide a finished message for relay. The documented handshake returns HTTP 402 with payment instructions before accepting a retry signed in USDC on Base. Sending is queued after the paid response, and the pricing table separates drafting, outbound sending, priority inbox access, and the one-time cost of claiming a custom inbox name.
