@ar-agents/aduana

ARCA Aduana (formerly AFIP / María) as drop-in tools for the Vercel AI SDK.

Look up Argentine customs declarations by SUSI / KIM / OM number, check the status of an in-flight despacho, and resolve NCM tariff codes — all from inside an agent.

Install

pnpm add @ar-agents/aduana

Usage

import { aduanaTools, HttpAduanaAdapter } from "@ar-agents/aduana";

const tools = aduanaTools({ adapter: new HttpAduanaAdapter() });
// Pass `tools` directly to Vercel AI SDK's generateText / streamText.

For testing, swap the HTTP adapter for the in-memory one:

import { InMemoryAduanaAdapter } from "@ar-agents/aduana";

const tools = aduanaTools({
  adapter: new InMemoryAduanaAdapter({
    despachos: [
      {
        identifier: { kind: "SUSI", value: "24001IM4001234A" },
        found: true,
        status: "canalizado_verde",
        operationKind: "IM4",
        ncmCode: "84713010",
      },
    ],
  }),
});

Tools

| Tool | Returns | |---|---| | aduana_lookup_despacho | Status, operation kind, NCM, registration date, Aduana office. {found: false} for unknown IDs — not an error. | | aduana_lookup_ncm | Description, whether currently in force, AEC + DIE percent. |

Errors

All errors extend AduanaError (which extends ArAgentsError from @ar-agents/core):

• AduanaValidationError — bad input
• AduanaUnconfiguredError — adapter not wired (default), see error message for setup steps
• AduanaApiError — non-2xx HTTP response (retryable for 5xx / 429)

Status

v0.1 — read-only against the public ARCA REST surface published in 2025. Write operations (registering a despacho) require WSAA cert handling and are out of scope for v0.1.
