PREISmonitoring observes what products actually cost and whether they are actually in stock across the online shops, marketplaces, and platforms monitored for your account, and it keeps the observation history. REST lives under /v1/*, MCP under POST /mcp. Customer data requires authentication. To discuss your requirements without an account, use POST /v1/inquiries or the MCP tool submit_inquiry.
