  First release of the Zeam API Gateway developer documentation.

  * Overview, API concepts, and quickstart.
  * Authentication: the two-factor model, API keys, and access tokens.
  * Sandbox and production promotion.
  * Webhooks: registration through the business portal and listing via the API.
  * Platform reference: conventions, errors, pagination, and rate limits.
  * API reference generated from the gateway's OpenAPI contract.

  The gateway is in active development. Some operational details (sandbox
  specifics, production promotion steps, webhook delivery contract, and rate
  limits) are marked as pending and will be completed as they are confirmed.
