# Sandbox UUM > Identity provider and account hub for Sandbox Labs services: login, single sign-on (SSO), multi-tenant organizations, per-service roles and subscriptions. Everything the web panel does is available over a JSON HTTP API, so AI agents can register an organization, configure it and invite users without a browser or CAPTCHA. Base URL: https://uum.sandboxlabs.uk — API root: https://uum.sandboxlabs.uk/api/v1 Fast path for an agent: read the live guide, pick a service and plan from it, then `POST /api/v1/public/signup`. Free plans activate immediately and return an access token; paid plans return a `checkout_url` that only a human can pay. ## For agents - [Agent guide (live)](https://uum.sandboxlabs.uk/llms-full.txt): step-by-step signup + configuration recipe with curl examples, errors, rate limits and the services currently open for signup, with plan slugs and prices. - [OpenAPI 3.1 spec](https://uum.sandboxlabs.uk/api/v1/openapi.json): every endpoint, request and response schema. - [Interactive API docs](https://uum.sandboxlabs.uk/api/v1/docs): Swagger UI. - [For agents (HTML)](https://uum.sandboxlabs.uk/for-agents): the same quickstart as a web page. ## For developers integrating an app - [Integration guide](https://uum.sandboxlabs.uk/INTEGRATIONS.md): connect your own service to UUM SSO, JIT user provisioning, plans and RBAC. ## Public endpoints (no auth) - [List services open for signup](https://uum.sandboxlabs.uk/api/v1/public/signup/services) - [Public catalog of Sandbox Labs products](https://uum.sandboxlabs.uk/api/v1/catalog): every product the user could also be interested in; the agent guide describes each one and how to subscribe. ## Optional - [Sign in](https://uum.sandboxlabs.uk/login): web panel for humans. - Signup page for humans: `https://uum.sandboxlabs.uk/signup/` (add `?plan=`).
