Caretta

Caretta is a Y Combinator-backed (W26) startup building a real-time AI platform for sales teams. Its assistant joins reps in live calls to take notes and surface relevant answers to information requests, questions, and objections in real time, drawing on an organizational knowledge layer it calls "Caretta Nous" that is built from company documentation, websites, internal playbooks, and top-performer conversations. After calls it supports teamspaces with analysis, morning briefs, and follow-up Q&A, and integrates with tools such as Zoom, Google Meet, Microsoft Teams, Salesforce, HubSpot, Pipedrive, Attio, Odoo, Cal.com, Slack, Telegram and Notion. The company raised $1.3M in pre-seed funding. Caretta's developer surface is agent-first rather than REST-first: it publishes a documented remote Model Context Protocol server at gateway.caretta.app/mcp with OAuth-scoped access to calls, transcripts and todos, a signed HMAC-SHA256 webhook surface that pushes transcripts, AI notes and evaluated metrics to customer endpoints, and a Zoom meeting-link integration. Its docs host serves llms.txt, an A2A agent card and a published Agent Skill. Caretta's own documentation states that a public REST API for endpoint management is planned but not yet available, so no OpenAPI description is published.

Caretta publishes 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Sales, Sales Intelligence, and Real-Time.

The Caretta catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Caretta’s developer surface includes engineering blog, signup flow, documentation, getting-started guide, authentication, and 24 more developer resources.

  description: Remote Model Context Protocol server that gives compatible AI clients OAuth-scoped access to the Caretta calls,
    transcripts and todos the signed-in user can already see. Seven documented tools cover listing and searching calls, retrieving
    a call with its transcript and todos, and listing, creating and updating todos. Authorization is browser-based OAuth with
    three product scopes (calls:read, todos:read, todos:write); no API key is issued. The endpoint advertises an RFC 9728
    OAuth protected-resource document and returns a WWW-Authenticate challenge to unauthenticated callers.
