COMPOSIO INSTANT

What is Composio Instant?

Composio Instant lets your agent use paid APIs like Openai without a separate account or API key for each one. New accounts start with $2 of free credit.

No Openai account or key

Your agent calls Openai through Composio, so there is nothing to sign up for, store, or rotate.

Pay per call, at cost

$0.10 per 1M input tokens ($0.20 long context); cache and output free; $2 max., paid from your Composio balance with zero markup.

Works in any agent

Claude, ChatGPT, Cursor, and other MCP clients, or your own code with the Composio SDK.

Works with your apps

Use Openai with Gmail, Slack, Google Sheets, and 1,700+ other apps you connect.
