arca-apocryphal-invoices

Screens a list of CUITs against APOC, ARCA's public registry of taxpayers flagged for issuing apocryphal (fake) invoices. Resolves in a single bridge call: the extractor downloads the whole daily ZIP itself (DownloadFile.aspx, ~45k CUITs), unzips it in-browser (DecompressionStream), indexes it by CUIT and returns only the CUITs you asked about.

No Clave Fiscal and no captcha: the bulk download is public. The per-CUIT web form does have an image captcha, so this skill deliberately ignores it and uses the full-file download instead. Nothing for the user to solve.

ARCA (ex AFIP) keeps its service URLs on afip.gob.ar. That is why the catalog domain reads ARCA but the tab must be on servicioscf.afip.gob.ar. The ZIP carries no CORS, so it is same-origin. Navigate to https://servicioscf.afip.gob.ar/Facturacion/facturasApocrifas/default.aspx first, then call.

The extractor lives as text in the site's localStorage (key arca-apocryphal-invoices), rebuilt on each call with synchronous eval. Stored once, persists across navigation and restarts.

Default action: just call (step 1). The call reports NEEDS_STORE when the extractor is missing or out of date; only then store (step 2) and call again.

Versioning. Gated by VER (must match version in the frontmatter). When evaluate.js changes, bump both.

1. Call (do this every run: params only, single bridge call)

await (() => {
  const KEY = "arca-apocryphal-invoices", VER = "1";
  const s = localStorage.getItem(KEY);
  if (!s || localStorage.getItem(KEY + ":ver") !== VER) return 'NEEDS_STORE';
  const fn = eval('(' + s + ')');
  return fn(document, { cuits: ["30707577963", "20428522568"] });
})()

Run this snippet verbatim. Never add an await before the eval. Only the outer await is allowed.

2. Store (only when step 1 returned NEEDS_STORE)

From a servicioscf.afip.gob.ar tab, evaluate the following with the bridge, replacing <FN> with the contents of evaluate.js (the ( async (root, params) => { ... } ) function). Keep VER equal to the call snippet's:

(() => {
  const KEY = "arca-apocryphal-invoices", VER = "1";
  const fn = (<FN>);
  localStorage.setItem(KEY, String(fn));
  localStorage.setItem(KEY + ":ver", VER);
  return 'stored';
})()

Returns "stored". Then go back to step 1.

Reading the data

• A CUIT in resultados is on the APOC base: treat it as a strong red flag. desde is when ARCA set the condition; publicado when it was published.
• limpios are the CUITs NOT in the base. That is NOT a clean bill, only that this specific list does not flag them.
• The Descripcion column ARCA ships is empty for every row today, so the signal is binary (listed / not listed) plus the dates.
• generado tells you how fresh the file is; ARCA regenerates it daily. Each call re-downloads (~500 KB), so pass all the CUITs of one screening in a single call rather than one call per CUIT.

Errors

• NEEDS_STORE: extractor missing or version-mismatched in this browser; run step 2 once, then retry step 1.
• fetch_failed / http NNN: not on servicioscf.afip.gob.ar (no CORS). Open that host and retry.
• not_a_zip / zip_method_N: ARCA changed the download format; the extractor needs updating.
• pass params.cuits ...: no valid 11-digit CUIT was supplied.
