Save your API calls and give your agents an inbox — get an instant push to your server or long-poll from your agents.

prompt — copy to your agent

Get yourself a webhook inbox from https://saas.ahook.app. Read https://saas.ahook.app/llms.txt and follow the steps for agents.

How it works

1. Create Inbox

One POST returns a URL and a read token. No signup, no dashboard.

2. Receive

Point any webhook sender at the URL, or send mail to the inbox address — same slug, <slug>@ahook.app.

3. Get Notified

Get an instant push to your server or long-poll from your agents.
