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 | $0.00064 | $0.00649 |
| Opus 5 | $0.00032 | $0.00324 |
| Sonnet 5 | $0.00013 | $0.00130 |
| Haiku 4.5 | $0.00006 | $0.00065 |
Grade A, and why
openapi-geo scanned grade A with 0 findings 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 2d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Openapi geo & real estate data
Four services; all use a Bearer token (see the openapi-auth skill).
Geocoding — https://geocoding.openapi.it
POST /geocode— address → coordinates and place detailsPOST /reverse— coordinates (or place ID) → address
Zip Codes (CAP) — https://cap.openapi.it
GET /cerca_comuni— search municipalities by name/region/provinceGET /comuni_base/{istat_code}/GET /comuni_advance/{istat_code}— municipality detailsGET /cap/{cap}— municipalities matching a zip codeGET /regioni,GET /province,GET /province/{code},GET /citta_metropolitane,GET /comuni_soppressi
Sandbox has a limited dataset; some parameters return fixed data.
Catasto (Italian cadastre) — https://catasto.openapi.it
Official paid lookups; document generation is async (POST → GET /{id} → GET /{id}/documento). Subject searches return personal data — GDPR care.
- Cadastral data requests:
POST /richiesta/{endpoint}/, status viaGET /richiesta/{id}(property data, holders, properties by subject, counts) - Address search:
POST /indirizzo,GET /indirizzo/{id}— properties at an address - Visura catastale (PDF):
POST /visura_catastale→GET /visura_catastale/{id}/documento - Visure ipotecarie (land registry):
POST /ipotecarie-ispezione_nazionale,POST /ipotecarie-elenco-note,POST /ipotecarie-dettaglio-nota→GET /ipotecarie/{id}[/documento] - Map extract (PDF):
POST /estratto_mappa→GET /estratto_mappa/{id}/documento - Reference data:
GET /territorio(provinces/municipalities),GET /territorio/conservatorie(Land Registry Offices)
Real Estate — https://realestate.openapi.com
POST /IT-rmv— property transaction details (comparables)POST /IT-sqm_value_start— basic €/sqm valuationPOST /IT-sqm_value_advanced— detailed valuation with sales and demographic data
Sandbox returns consistent predefined data for testing.

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.

openapi-geo is a skill published in the GitHub repository openapi/openapi-skills (2 stars, last pushed 2mo ago), licensed MIT. It adds 64 tokens to every session and 649 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
