Early access

There is no sign up yet, and no dashboard to log in to. Issuing an API key needs an account and a project you can see, and neither exists outside a developer machine today.

What does exist, and what you can read right now:

• The API reference, generated from the OpenAPI document the server itself serves.
• The CLI and the MCP server, both installable with npx once they are published to npm.
• The data model, the time zone rules and the error catalogue.

Ask for early access

There is no form here, because there is nothing behind one. Write to hello@bookrail.dev, subject Bookrail early access, and say what you are building and roughly how many bookings a month it makes. That is the whole process, and it is answered by a person.

The address is hello@bookrail.dev, in case your browser does not open mail for you. Nothing on this site collects anything: no form, no analytics, no cookies.
