Every ARCA service
A declarative catalog covers invoicing, exports, MTXCA, bonds, tourism, FCE MiPyME, the A4/A5/A10/A13 registries, constancia, agro and remittances — plus a generic engine for any other operation.
Arcanum
The gift for accountants: every ARCA service, from your browser.
Arcanum is a REST gateway and web panel for the web services of ARCA (Argentina’s tax authority, ex-AFIP). You install one Docker image, open the browser and operate all the ARCA services without ever fighting SOAP. The WSAA signing is 100% local — the private key never leaves your server nor passes through any third party — and everything can be automated from n8n. No accounts, no subscriptions, no middlemen. Arcanum is an independent satellite of the Escriba ecosystem. Not affiliated with ARCA/AFIP.
What it does
Section titled “What it does”100% local WSAA signing
The private key is stored AES-256-GCM encrypted in Postgres and signs on your server. The Token/Sign is cached 12h, renewed proactively and retried only when ARCA rejects it.
Live-editable catalog
ARCA changes endpoints often — the superadmin edits them from the UI, saved in Postgres and audited, without redeploying.
Invoicing with CAE
Issue and obtain the CAE with auto-numbering, credit/debit notes, prior amount validation, idempotency (no double-CAE) and a legal PDF with ARCA’s QR.
Web panel with metrics
Emissions, per-service uptime, latency, tokens and certificates about to expire — plus client onboarding and a step-by-step activation guide per service.
Automatable from n8n
A clean REST surface with an API key: wire ARCA into your automations without touching SOAP.
Part of the Escriba Suite
Section titled “Part of the Escriba Suite”Arcanum is a self-hosted, open-source (Apache-2.0) member of the Escriba family. Like the rest of the suite it runs on your own hardware, keeps the sensitive work local, and shares the same design language and single sign-on through Lockatus.
