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 | $0.00041 | $0.00583 |
| Opus 5 | $0.00020 | $0.00292 |
| Sonnet 5 | $0.00008 | $0.00117 |
| Haiku 4.5 | $0.00004 | $0.00058 |
Grade A, and why
company-lookup 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Nordic Company Lookup
Trigger
Verifying company information, checking business legitimacy, looking up board members, or validating organization numbers across Nordic countries.
Workflow
-
Identify the country and ID format:
- Norway: 9 digits (e.g.,
923609016or923 609 016) - Denmark: 8 digits (e.g.,
10150817orDK-10150817) - Finland: 7+1 format (e.g.,
0112038-9) - Sweden: 10 digits (e.g.,
5560125790or556012-5790)
- Norway: 9 digits (e.g.,
-
Search by name — Use the country-specific search tool:
norway_search_companies— supports filters: org_form, municipalitydenmark_search_companies— returns single best match; try name variationsfinland_search_companies— use exact legal name or filter by company_form/location- Sweden has no name search; you need the org number
-
Get company details — Use the country-specific detail tool:
norway_get_company,denmark_get_company,finland_get_company,sweden_get_company
-
Check governance (Norway) — Use
norway_get_rolesfor board members, CEO, and auditors. Usenorway_get_signature_rightsto check who can legally sign. -
Batch validation — Use
norway_batch_get_companiesto verify multiple org numbers at once. -
Swedish documents — Use
sweden_get_document_listandsweden_download_documentfor annual reports (requires OAuth2 credentials).
Common Scenarios
Vendor verification
Look up the company, check it's active (not bankrupt), verify the signer has authority.
Cross-border presence
Search the same company name across multiple country registries to find subsidiaries.
Data quality
Batch-validate a list of org numbers to flag invalid, bankrupt, or missing entries.
Guardrails
- All APIs are free and read-only. No authentication needed for Norway, Denmark, and Finland.
- Sweden requires
BOLAGSVERKET_CLIENT_IDandBOLAGSVERKET_CLIENT_SECRETenvironment variables. - Danish search returns only one result. Try variations for large companies ("Novo Nordisk A/S", "Novo Nordisk Denmark").
- Finnish common names return many results. Use exact legal names or filters.
- Spaces and dashes in org numbers are stripped automatically.
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.
