Agent on a schedule
Once a week, an agent emails you the cash position and the largest outgoing payments.

Plaid stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in Plaid waits for your approval, one call at a time. How adapters work

Good to know

Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow.
Pricing shows once you apply for Production access. Free Trial plans are for new teams in the US and Canada.
