# Provision a temporary endpoint with no account and no API key

`POST /api/start`

## Request

- Base URL: `https://webhook-studio.com`
- URL: `https://webhook-studio.com/api/start`
- Auth: none required

The only unauthenticated write. Returns a 3-day endpoint: ingest_url for the provider, inbox_url for the human. No /v1 access — registering (free) claims it permanently. Without cookie persistence every call mints a NEW endpoint, so call it once and reuse ingest_url.

## Request body

- object
  - `ref` string
  - `provider_hint` string

## Response `200`

Provisioned

- object
  - `endpoint_id` string
  - `inbox_url` string
  - `ingest_url` string
  - `expires_at` string
  - `expires_in_days` integer
  - `reused` boolean

## Other responses

- `409`: Error
- `429`: Error
