Getting Your API Key

An API key will be necessary to interact with your Composer account via API. For example, saving a Composer Symphony for later or viewing statistics about your portfolio.


Trading a symphony will require a paid subscription, although you can always liquidate a position regardless of your subscription status. Composer also includes a 14-day free trial so you can try without any commitment.


Please note that, due to model limits at some AI companies, you may need to be on a paid plan in order to link with Composer via our MCP server. 


Get your API key from Composer by following these steps:

  1. If you haven't already done so, create an account.
  2. Open your "Accounts & Funding" page

  3. Request an API key
