# Landing API

The landing site exposes one machine-callable action: joining the Converge
waitlist.

## Waitlist signup

```http
POST https://use-converge.com/api/subscribe
Content-Type: application/json

{"email":"you@example.com"}
```

Call this only with the user's own email address and their explicit consent.
The service sends a double-opt-in confirmation email; the address is not added
until the recipient confirms it.

The endpoint is unauthenticated and returns a JSON object with `success` and
`message` fields. A successful request normally returns HTTP 200. Missing or
non-string `email` values return HTTP 400.

The complete request and response schema is available in
[`openapi.json`](/openapi.json).
