Start on the free plan — no card, no trial timer. The paid plan raises the monthly quota and adds LLM reading of PDF-only filings.
€0 / month
For trying it out and for occasional lookups.
get_operation is free and unlimited€15 / month excl. VAT
For regular use, and for reading filings that exist only as PDF.
Prices exclude VAT. Belgian businesses are charged 21%; give your VAT number at checkout and other-EU business customers are reverse-charged.
Payments are not live yet: the paid plan's limits are real and enforced, but there is nothing to buy today. Mail support@nbb-mcp.be if you need the paid quotas in the meantime.
| Tool | Billable | Why |
|---|---|---|
search_company |
yes | Searches the KBO denomination index. |
get_annual_accounts |
yes | Fetches and parses a filing, or attaches you to one already being fetched. |
get_operation |
no | Polling. The API is asynchronous, so a client told to poll every three seconds must not be charged for obeying. |
Quotas are per calendar month and reset on the 1st. Both plans allow 30 requests per minute per key.
Tool calls return an error explaining that the monthly quota is reached, with a link to upgrade. Nothing breaks and no key is disabled — the next month starts at zero again.
Your subscription runs to the end of the period you paid for, then the account drops back to the free plan. Your API key keeps working at free quotas; there is no cut-off and nothing to re-issue.
Not yet: the payment flow is still being built, so nothing is charged and no invoice is issued today. When it goes live, every payment gets a VAT invoice, and Belgian business customers additionally receive a structured e-invoice over Peppol — what domestic Belgian B2B invoicing has legally required since 1 January 2026.
Because that path calls an LLM over a scanned filing, which costs real money per document. It is charged once per filing ever: the extraction is cached permanently (a filed annual account never changes), so the second person to ask for the same PDF filing pays nothing against their cap.
Email address, one link, and your key is on the account page.
