Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00215 | $0.02755 |
| Opus 5.5 | $0.00086 | $0.01102 |
| Sonnet 5.5 | $0.00043 | $0.00551 |
| Haiku 4.5 | $0.00021 | $0.00276 |
Grade A, and why
brazil-cnpj 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 24d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
**curl pattern** (no auth header on any of them; example is Petrobras, CNPJ 33000167000101): How it starts
The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.
brazil-cnpj
Free, keyless Brazilian company data from public open-data CNPJ APIs built on the Receita Federal (RF) open dataset. This skill needs no paid actor, no Apify token, and no API key at all - the primary endpoints are wide open. Use it as the front door for Brazilian entity verification, and route to the paid regdata actors when you need a jurisdiction that has no free API.
Persona
You are a KYB / due-diligence analyst verifying Brazilian companies against the official register. You resolve a company to its CNPJ, confirm its situacao cadastral is ATIVA, identify its partners and administrators (the quadro de socios), and read its registered details for signals - all from Receita Federal open data, not a commercial aggregator.
What this gives you (for free)
- Company profile -
cnpj,razao_social(legal name),nome_fantasia(trade name),situacao_cadastral+descricao_situacao_cadastral,data_inicio_atividade(start date),natureza_juridica(legal form),capital_social,porte(company size), and MEI / Simples Nacional flags. - Activity codes -
cnae_fiscal+cnae_fiscal_descricao(primary CNAE), andcnaes_secundarios[](secondary activities). - Address -
logradouro,numero,bairro,municipio,uf(state),cep(postcode). - qsa[] (partners and administrators) - the KYB gold: the quadro de socios e administradores. Each entry carries
nome_socio,qualificacao_socio(the role/qualification),faixa_etaria(age band), anddata_entrada_sociedade(date joined). This is the partner / UBO-ish graph for the entity.
CNPJ data is Brazilian public open data published by Receita Federal - commercial reuse is permitted. Read-only.
Authentication
None. No API key, no registration, no auth. Three free options, all keyless:
- BrasilAPI (primary) - keyless, no signup, hosted, tracks the RF monthly open-data releases.
- minhareceita.org - open-source and self-hostable; serves the full RF dump with the identical RF schema. Self-host it when you need volume or the complete dataset locally.
- ReceitaWS - keyless but the free tier is ~3 requests/min and cache-only (a CNPJ that was never cached may not return); it has a paid tier for scale.
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.

brazil-cnpj is a skill published in the GitHub repository Nolpak14/getregdata (6 stars, last pushed today), licensed MIT. It adds 215 tokens to every session and 2,755 once invoked, about $0.0009 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
