Email API for a new era.

{  "id": "evt_7d10",  "type": "email.received",  "created_at": "2026-08-31T09:12:40Z",  "data": {    "email_id": "eml_2b91",    "thread_id": "thr_8f2c",    "from": "marco.lind@lindmetall.de",    "to": ["nora@northwind.io"],    "subject": "Preise Blech 3mm",    "snippet": "Hallo, Dana ist bis Freitag im Urlaub. 500 Stück 3mm …",    "category": "human",    "attachments": [      { "filename": "Angebot-4471.pdf", "preparation": "ready" }    ]  }}

Marco replied instead of Dana, with a new subject. Same thread, human, and the scanned quote he attached was read before this fired.

import { verifyWebhookRequest } from "aiinbx/webhooks" export async function POST(request: Request) {  const event = await verifyWebhookRequest(    request,    process.env.AI_INBX_WEBHOOK_SECRET!,  )   // Every inbound mail arrives here. Only people are worth a run.  if (event.type !== "email.received" || event.data.category !== "human")    return Response.json({ ok: true })   const thread = await aiinbx.threads.retrieve(event.data.thread_id)  const reply = await agent.run(thread.messages)   await aiinbx.threads.reply(thread.id, { text: reply })  return Response.json({ ok: true })}

Verify, drop what is not a person, read the whole thread, reply into it. The reply takes its recipients and subject from the thread, so it lands where Marco will read it.

curl https://api.aiinbx.com/api/v2/emails \  -H "Authorization: Bearer aibx_live_…" \  -H "Content-Type: application/json" \  -d '{    "from": "nora@northwind.io",    "to": "dana@lindmetall.de",    "subject": "RFQ 4471 — 3mm brushed sheets",    "text": "Could you quote 500 sheets of 3mm brushed stainless?",    "suppression_key": "q4-outbound"  }'

The same call over plain HTTP. Every SDK namespace is a path under /api/v2.
