Buttondown API Skill

This skill enables you to interact with the Buttondown newsletter platform via its REST API. The API follows standard RESTful conventions, so operations are straightforward CRUD calls.

Authentication

All requests require the user's API key, available from https://buttondown.com/requests.

  • Use the BUTTONDOWN_API_KEY environment variable
  • Send it as: Authorization: Token $BUTTONDOWN_API_KEY

Before making any API call, verify the env var is set. If it's missing, tell the user to set it:

export BUTTONDOWN_API_KEY="your-api-key-here"
