How do I create a Fountain API key?
Create API keys from your project settings at fountain.fm/studio/projects and send them as a Bearer token.
API keys are created from your project at fountain.fm/studio/projects. Every key starts with fountain_, so you can recognize one at a glance.
To use a key, send it in the Authorization header of each request:
Authorization: Bearer YOUR_API_KEY
The base URL for the API is https://api.fountain.fm/v1.
Keep your key secret
Treat an API key like a password. Do not paste it into logs, shared documents or code you publish anywhere. If you are working with an agent, store the key in an environment variable or a .env file rather than typing it into the chat.
When do you need one?
If you connect an agent through the MCP server, you sign in with OAuth and do not need an API key at all. Keys are for calling the API directly over HTTP. From your own scripts, tools or integrations.
API and MCP calls are unlimited on every plan, so there is no metering on the calls themselves. Some actions, such as generating a transcript, cost credits.
