Electronic invoicing for developers
Send clean JSON, get signed UBL 2.1 XML, pre-validation and the CUFE in milliseconds. Built for teams shipping modern software in Colombia.
Built for the modern production stack
One REST call. The DIAN standard, solved.
import { CufeaClient } from '@cufea/sdk';
// Inicializar cliente con clave de Sandbox o Producción
const cufea = new CufeaClient({ apiKey: process.env.CUFEA_KEY });
// Generar factura electrónica, firma X.509 y validación DIAN

}Fiscal infrastructure,
ready for AI agents.
An MCP server wired to the DIAN and the Cufea API. Pick your agent and connect it in one click — issue, validate and query electronic documents without building UBL payloads by hand.
Set up the Cufea MCP server in Claude:
claude mcp add --transport http cufea \
https://mcp.cufea.com/co \
--header "Authorization: Bearer <token>"
Use my Cufea token (it's in the CUFEA_TOKEN variable) and, once done, confirm the cufea tools are available.
First-class developer experience
The DIAN shouldn't be a headache. We built the exact primitives your team needs so you never babysit broken XML.
Native idempotency
Prevents duplicate invoicing on transient network failures or double-clicked payment flows. Cufea deduplicates requests automatically at the edge.
HMAC-signed webhooks
Real-time events with invoice.dian_approved and a cryptographic signature you verify with your secret.
PDF & QR at the edge (<80ms)
Ultra-fast vectorial rendering of regulatory representations, no heavy Chromium backends slowing your stack down.
Deterministic sandbox
Test edge cases, tax rejections and state-server failures without issuing real legal invoices or using your digital certificate.
Immutable UBL 2.1 vault
Mandatory 5-year legal custody under AES-256 at rest with cryptographic traceability and direct tax auditing.
Integrate in 5 minutes
Designed to sit next to your existing stack without touching your internal database logic or your frontend.
Configure your secure sandbox or production credentials in a single line.
Send items and fiscal data. Cufea compiles and signs the UBL 2.1 XML.
Receive DIAN pre-validation and the CUFE on your own infrastructure.
import { CufeaClient } from '@cufea/sdk';
export const cufea = new CufeaClient({
apiKey: process.env.CUFEA_SECRET_KEY!,
environment: 'sandbox', // 'sandbox' | 'production'
timeoutMs: 5000
});
// Comprobar conectividad directa con el Gateway DIAN
const { status, dianGateway } = await cufea.ping();
console.log(`Cufea: ${status} | DIAN: ${dianGateway}`);Start issuing in minutes
No commercial contracts, no slow paperwork. Generate your test keys instantly and validate your first UBL 2.1 documents today.
