SLUG: LANGBASE

Description

Langbase is a serverless AI developer platform that enables developers to build, collaborate, and deploy AI agents and applications with composable AI infrastructure.

Authentication Details

API Key

generic_api_key

stringRequired

Connecting to Langbase

Create an auth config

Use the dashboard to create an auth config for the Langbase toolkit. This allows you to connect multiple Langbase accounts to Composio for agents to use.

Select App

Navigate to Langbase.

Configure Auth Config Settings

Select among the supported auth schemes of and configure them here.

Create and Get auth config ID

Click “Create Langbase Auth Config”. After creation, copy the displayed ID starting with ac_. This is your auth config ID. This is not a sensitive ID — you can save it in environment variables or a database. This ID will be used to create connections to the toolkit for a given user.
