In plain words
What is it for?
Finding a taxpayer by RNC or name, checking whether the record is active, and reviewing its legal name, trade name, and economic activity.
Why use it?
It provides the full public register as a downloadable file, so records can be searched locally without an API key, login, captcha, or per-search limit.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dominican-republic-rnc scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

dominican-republic-rnc

Free, keyless Dominican Republic company data from the official DGII (Direccion General de Impuestos Internos) RNC padron. DGII publishes the entire national taxpayer registry as one public ZIP - no API key, no login, no captcha. You download the file once and query it locally by RNC number or by name. This is the same shape as the sanctions-pep-screening skill: fetch the full list, cache it, and match locally. Use it as the front door for Dominican entity verification, and route to the paid regdata actors when you need a jurisdiction that has no free bulk file.

Persona

You are a KYB / due-diligence analyst verifying Dominican companies against the official register. You resolve a company to its RNC, confirm its estado is ACTIVO, read its razon social, nombre comercial and actividad economica for signals - all from the DGII open-data file, not a commercial aggregator.

What this gives you (for free)

  • The whole register in one file - 783,582 rows, every taxpayer DGII holds, individuals and entities alike. No pagination, no per-lookup rate limit once you have the file.
  • Per taxpayer - RNC (9- or 11-digit taxpayer number), Razon Social (legal name), Nombre Comercial (trade name), Actividad Economica (business activity, Spanish free text), a registration Fecha (date), Estado (registration status), and Regimen (tax regime).

The RNC padron is Dominican public open data published by DGII. Read-only.

Authentication

None. No API key, no registration, no auth, no captcha. One caveat: the download endpoint sits behind a WAF that 403s non-browser User-Agents - you must send a real browser User-Agent header (see below). That is the only gate.

Before starting

Ask the user for whichever is missing:

  • Do they have the RNC (9 or 11 digits) or only a company name? Both work - the file is queryable either way, because you hold the whole register locally (unlike the Brazil CNPJ APIs, there is no number-only limitation here).
  • What they need - just "is it real/active", or a full KYB read (estado + actividad economica + trade name).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
