Documenso 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 Documenso 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.
If you host it yourself, the API of your own installation must be reachable over HTTPS from the internet, so the adapter can call it.
The free plan is limited to 5 documents per month.

The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.

Check if [software] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
