}Point Claude Code at your mailbox
The inbound API was written for agents. A local Claude Code session reads your mail, writes a draft and leaves it waiting — the send button stays yours.
Authorization: Bearer eml_live_…
GET /api/v1/messages?status=open&domain=voorbeeld.nl
PATCH /api/v1/messages/{id} {"handled": true}
PATCH /api/v1/messages/{id} {"draft": "<p>Dag Jan, dat kan zeker…</p>"}Poll and claim
Filter by domain, address, status or time. Whoever claims a message keeps it, so two sessions never answer the same question.
Leave a draft
As one block of HTML, or as question-and-answer pairs that land under the paragraph each one responds to.
Never sends
The draft appears on the message, labelled with the key that wrote it. A person reads it, edits it and presses send.
Agents find the documentation themselves at /llms.txt — machine-readable, with scopes, error codes and examples.
