  CORRECTED 2026-09-07. Express Gateway bills nobody. It is free, Apache-2.0
  self-hosted software with no hosted tier, no meter and no invoice — its pricing
  page returns 404 and its former commercial sponsor LunchBadger is gone. The
  billingModel, focusColumns, meters and unitEconomics below were written by an
  API Evangelist bulk sweep dated 2026-05-04 (roadmap#35) and describe a
  usage-billed SaaS that does not exist. They are retained only as a FOCUS-shaped
  template and MUST NOT be read as Express Gateway pricing or billing behaviour.
  The only real cost of running Express Gateway is the operator's own
  infrastructure and Redis. See plans/express-gateway-plans-pricing.yml, which
  records plan_count 0.
