[How adapters work](https://hypamoon.com/docs/adapters) ### 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. - Limit of 60 requests per minute. ## Try it in your chat Fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for Homerun. API docs: https://developers.homerun.co/. Read: \[what\]. Write: \[what, or nothing\].
