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

merit-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.

Merit Company Lookup — äriregister free services

Two FREE (tasuta), read-only services from the Estonian Business Register, exposed via elnora-merit ariregister. Nothing here writes to the books or costs money.

When to use

  • Before creating a customer/invoice — pull the authoritative legal name, VAT number, and address instead of typing them by hand or trusting a stale value.
  • Before sending an e-invoice — confirm the recipient actually has an active e-invoice channel, so you don't send into a void.

Commands

Requisites (needs credentials)

elnora-merit ariregister requisites <regCode> [--include-deleted] [--lang eng]

Returns JSON: regCode, name, vatNo, status, statusText, address {street, ehakCode, ehakText, postalIndex}, registryLink. status R = registered/active; K = deleted.

Example:

$ elnora-merit ariregister requisites 16818352
{"regCode":"16818352","name":"Elnora AI OÜ","vatNo":"EE102672514","status":"R", ...}

E-invoice capability (no credentials)

elnora-merit ariregister e-invoice-check <regCode> [<regCode> ...]

One row per code: status OK = active e-invoice relationship (canReceiveEInvoice: true), MR = none/invalid; plus name and provider (operator).

Mapping requisites to a Merit customer

äriregister field Merit customer field
name Name
vatNo VatRegNo
regCode RegNo
address.street Address
address.ehakText City / County
address.postalIndex PostalCode

Setup & limits

  • Requisites needs ARIREG_XML_USER / ARIREG_XML_PASSWORD in the environment or ~/.config/elnora-merit/.env. Create an XML-authorised user in the e-äriregister portal (Haldus → Kasutajate haldamine) and use that account's credentials. A "credential rejected" error means they are missing or wrong.
  • E-invoice-check needs no credentials at all.
  • Only these two free services are wired. Detailed company data, beneficial owners, and representation rights are billable in the register and are intentionally not exposed.
  • Endpoint defaults to production; set ARIREG_XML_ENV=test to hit the demo endpoint.

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.
