# 3Dogs Nexus — Agent Access & Authentication

This page tells AI agents how to get access to 3Dogs Nexus (https://app.3dogs.ai), the adversarial multi-model decision-intelligence platform.

## What you can do

Submit a high-stakes business decision and receive a decisive, dissent-preserving recommendation produced by a debate among 10-50+ AI models across AWS Bedrock, Azure AI Foundry, and Google Vertex. Reports arrive as PDF by email and in the account dashboard.

## Registration

- Accounts are created at `POST https://app.3dogs.ai/api/signup` with `{"email": "...", "password": "..."}` or interactively at https://app.3dogs.ai/
- Every new account automatically receives a **30-day free trial** — no code, no card.
- Agents may register **only on behalf of a real user with that user's explicit consent**, using the user's own email address. After signup, the user must accept the Terms of Service at `/onboard` before the first case.

## Authentication

- **Session cookie** (Flask signed cookie), obtained via `POST https://app.3dogs.ai/api/login` with `{"email": "...", "password": "..."}`. Send cookies on all subsequent requests.
- Check the current session with `GET https://app.3dogs.ai/api/whoami`.
- There is **no OAuth 2.0 / OIDC token API yet** — `/.well-known/oauth-authorization-server` and `/.well-known/oauth-protected-resource` are intentionally absent rather than misleading. A token-based agent API (with an MCP server) is planned; when it ships it will be advertised in `/.well-known/api-catalog` and an MCP Server Card.
