# Help

frwrd.to turns long links into short ones, with a QR code and click numbers
for each. It also hosts bio pages that you write in Markdown, and every link
on a page becomes a short link with its own numbers. A workspace belongs to
a domain, and there are no user accounts.

## Four ways in

You can do the same things through each of them:

- **Web app** at [app.frwrd.to](https://app.frwrd.to): sign in with your key, then manage links, pages and numbers.
- **REST API** at `https://api.frwrd.to`, under `/v1`. The Bit.ly compatible `/v4` sits next to it for tools that already speak Bit.ly.
- **MCP** at `https://api.frwrd.to/mcp`, for agents such as Claude.
- **The `frwrd` command-line tool**, for the shell and for scripts.

## One key opens all of them

Your workspace key (it starts with `fw_`) is the only credential. The web
app, the API, MCP and the command-line tool all take it, and it is shown once
when you create the workspace. Keep it in a password manager, and never put
it in a URL or on a page.
