Gradient Labs

Gradient Labs builds "Otto", an AI customer support agent that autonomously handles complex, end-to-end support conversations for regulated and financial services businesses. The API lets you start and drive conversations, stream customer messages, hand off to human agents, execute business actions/tools, and manage the knowledge base the agent reasons over, with signed webhooks delivering the agent's outbound messages and events.

Gradient Labs publishes 5 APIs on the APIs.io network, including Actions & Tools API, Conversations API, Hand-off API, and 2 more. Tagged areas include AI, Customer Support, AI Agent, Conversations, and Financial Services.
