Ask in your own words

Sign in with OAuth, pick the companies and whether the connection may write. Your AI assistant sees the same operations you do. Irreversible tools are labelled, and MCP clients ask before running them.

How much does the API cost?

API keys and webhooks are part of the paid plans on the pricing page. MCP sign-in with OAuth works on every plan.

Can AI delete something?

Tools that change data irreversibly are labelled, and MCP clients ask before running them. Issuing a document and posting have legal effect, so confirm them.

What currency are amounts in?

Whole numbers in haléře: 100 is CZK 1. For other currencies, hundredths of that currency.

Your first invoice is a few minutes away.

Create your company, fill in the customer from ARES by IČO and send an invoice with QR payment.
