Support
How to contact Ärikratt and what to check when the MCP server refuses a call.
Contact
E-mail arikratt@r-53.com. We aim to reply within 5 working days. The publisher is R-53 OÜ, registry code 12351041.
Sign-in
Sign in with Google, or with e-mail and password. ChatGPT and Claude connect with OAuth. Other clients use a personal API key from the key page.
Limits
Standard limits per key: 2,000 successful calls a month, 200 a day and 500 distinct companies a day. Past a limit the server answers HTTP 429.
Data freshness
Answers use dated snapshots, not the official register. Business-register files and the EMTA tax-debt list are daily; EMTA tax and turnover figures are quarterly. Each answer carries its source and as-of date.
Wrong or missing data
If data is wrong or missing, call the MCP submit_feedback tool, or e-mail us.
