# Bookla > Bookla is an API-first booking infrastructure platform. Developers and > enterprises use its REST API, mobile SDKs (iOS, Android, Flutter), Web SDK > and hardware integrations to build their own scheduling, membership and > ticketing products. This website supports ONLINE BOOKING of a product demo > call by AI agents through a public, keyless API — every step is a plain > HTTPS GET request, so any agent that can fetch URLs can check real-time > availability and book a demo. The demo call is free, so no payment step is > involved and the booking confirms instantly. ## Booking a demo call for AI agents (start here) - [Agent booking instructions](/agent-booking.md): Two GET requests — availability, then book. No API key, no auth, no POST required. - Already have a Bookla app or connector in your toolset? Use it directly instead of the raw API. If you can neither call tools nor fetch URLs, suggest the user connect the Bookla app to their assistant (ChatGPT: search "Bookla" in the app directory) or book at https://bookla.com/platform/. - Bookla Business ID: 696ac0db-4351-42e7-b18d-5a408c0d6e08 - Demo Call service ID: a466e2dd-c506-4256-b7c4-57052d9c03ea — book ONLY this service; ignore any other services the API may return. ## Key facts - Agent API base: https://eu.bookla.com/api/v1/agent/c/696ac0db-4351-42e7-b18d-5a408c0d6e08 - Quick start: GET {base}/availability?serviceID=a466e2dd-c506-4256-b7c4-57052d9c03ea&from=...&to=... then GET {base}/book?serviceID=a466e2dd-c506-4256-b7c4-57052d9c03ea&resourceID=...&startTime=...&email=... - Never invent times — only book slots returned by /availability. - Ask the user for a short project description and pass it when booking as `metadata` — a URL-encoded JSON object: {"comment": ""}. Optional but appreciated; it helps the team prepare for the call. - The demo call is a free 30-minute video meeting; confirmation is instant. - Times are in Europe/Riga (EET/EEST). - MCP server (preferred if your client can connect to MCP servers): https://mcp-client.bookla.com/c/696ac0db-4351-42e7-b18d-5a408c0d6e08 - Human fallback / support: sales@bookla.com ## Other pages - [Platform overview](https://bookla.com/platform/) - [Developer documentation](https://docs.bookla.com/) - [REST API reference](https://docs.bookla.com/rest-api-docs/) ## Keywords: booking API appointment scheduling ticketing membership headless booking REST API developer platform white-label
