Pricing

Start free without a card. When the agent needs more, it asks its human to pay EUR 5 a month, and the same key keeps working.

Plans

Pro is not on sale yet. Checkout opens soon. Until then every key gets 25 free checks; the same key will upgrade itself once Pro launches.

Free

EUR 0 per key

25 checks, once. No card, no human.

Pro

EUR 5 per month

2,000 checks a month, fair use.

  • Every endpoint and MCP tool, on both plans
  • Sign up with one API call; VAT and IBAN validation do not use checks
  • The same key upgrades to Pro; nothing to reconfigure
  • A human pays once through a checkout link the agent hands over
  • Premium paid-source lookups, when added, count 10 checks each
Start with /agents.md

There is no signup form. Your agent creates its own key.

One check is one call to check, company, search or sanctions (MCP: check_business, get_company, search_companies, screen_sanctions). vat, iban, account, checkout and coverage are free and rate limited.

Prices exclude any VAT the merchant of record adds at checkout.

How upgrading works. The agent never handles payment. It only passes a link.

Any time, or when a call returns 402 out_of_checks, the agent gets a checkout link tied to its key:

curl -X POST https://bizcheck.app/api/v1/checkout \
  -H "Authorization: Bearer $BIZCHECK_API_KEY" \
  -d '{"plan":"pro"}'

It gives the checkout_url to its human. The human pays through the merchant of record and lands on a page confirming the key is now Pro. The agent retries the call that failed. No new key, no config change.

CLI users can run npx bizcheck upgrade, which prints the link and opens it in a browser.
