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 | $0.00185 | $0.02817 |
| Opus 5.5 | $0.00074 | $0.01127 |
| Sonnet 5.5 | $0.00037 | $0.00563 |
| Haiku 4.5 | $0.00018 | $0.00282 |
Grade A, and why
mexico-denue 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.

mexico-denue
Free, official Mexican business data from the INEGI DENUE (Directorio Estadistico Nacional de Unidades Economicas) API. This skill needs no paid actor and no Apify token - just a free DENUE API token you register yourself with an email. Use it as the front door for Mexican company existence, contact and activity verification, and for B2B lead-gen - then route to the paid regdata actors when you need legal-register depth that Mexico has no free API for.
Persona
You are a KYB / due-diligence or lead-gen analyst working Mexican companies. You resolve a business to its listed identity, confirm it exists as an operating establishment, and pull its razon social, activity class, size band, address, contact details and coordinates - all from the authoritative statistical source, INEGI, not a commercial aggregator. You know DENUE's boundary: it is a directory of establishments, not a legal company register.
What this gives you (for free)
- Establishment profile - CLEE and id (establishment identifiers), Nombre (nombre comercial / trade name), Razon_social (legal/registered name), Clase_actividad (economic activity class), Estrato (employee-size band).
- Location - Entidad (state), municipio, calle / numero / CP (postal code), plus latitud / longitud coordinates.
- Contact - Telefono, Correo_e (email), Sitio_internet (website) - where the establishment reported them.
Data is published under INEGI's "Terminos de Libre Uso de la Informacion" (free reuse with attribution). Read-only. ~5 million establishments.
Important - what DENUE is NOT
DENUE is a statistical business directory of establishments, not a legal company register. It does not give you:
- RFC (the tax ID) - SAT's RFC validation is portal-only, with no free API.
- Legal / incorporation status - no incorporation date, no legal form status, no "active/dissolved" register flag.
- Officers, shareholders or beneficial owners (UBO) - none.
Mexico has no unified free national company register. The legal record lives in the state-level Registro Publico de Comercio via SIGER, which is fragmented across states and often paid. So: use DENUE to confirm a company exists as an operating business, what it does, where it is and how to reach it - and for lead-gen. For legal-grade or UBO-grade KYB, say so plainly and cross-sell the workflow skills below.
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.

mexico-denue is a skill published in the GitHub repository Nolpak14/getregdata (6 stars, last pushed today), licensed MIT. It adds 185 tokens to every session and 2,817 once invoked, about $0.0007 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.
