API pública para timbrar **CFDI 4.0** usando la infraestructura de Facter. **Modelo comercial:** un **cliente principal** (plan PREPAGO) compra timbres; sus **emisores** (cada uno un tenant con su propio RFC y CSD) consumen del saldo del principal. El contrato de entrada es el **JSON canónico CFDI 4.0**: el integrador envía el comprobante completo (Emisor, Receptor, Conceptos, Impuestos, Complemento...). Facter **valida** consistencia aritmética y contra catálogos SAT pero **no recalcula** totales — tu sistema es el sistema de registro. **Ambientes:** prueba en **Demo** `https://demo.facter.com.mx/api/ext/v1` (sandbox de pruebas, sin cobro real, datos efímeros) y, cuando estés listo, pasa a **Producción** `https://v2.facter.com.mx/api/ext/v1` (timbrado real, consume timbres). Necesitas **una cuenta y una API key por ambiente**; la key de un ambiente no funciona en el otro. El host define el comportamiento. **Autenticación:** `Authorization: Bearer fct_live_xxx`. **Idempotencia obligatoria** en endpoints mutadores vía header `Idempotency-Key`. Toda respuesta incluye `X-Request-Id` para soporte. Documentación completa, quickstart y ejemplos: https://v2.facter.com.mx/developers
