3 · Download the datasets

Five ready-made, daily-fresh lists. Choose the format via the extension: .json or .csv. No sign-up, no key.

Every row also carries the uptrend (trend12) and the three buy rules of the strategy (kaufregeln): fair value at least 30% above the price, Quality Score of 50 or more, uptrend. New columns are always added at the end, existing ones never move.

Provenance: our fair value from multiple models on company-reported fundamentals (regulatory filings) plus third-party market data. Update frequency: daily. Every response carries snapshot_date and updated_at. Where we withhold a valuation, you get null instead of a number.

4 · In your AI assistant (ChatGPT, Claude and others)

Connect Fair Value Calculator to ChatGPT, Claude, Perplexity and others via our MCP server. The assistant can then find a stock, fetch the fair value with its range, verdict, quality score, trend and buy rules, get a quick snapshot, screen for undervalued stocks, compare several stocks, show your watchlist, add stocks to your watchlist, remove stocks from it, switch the email alert (Pro) and suggest stocks that fit your watchlist (Pro). For the AI connection a free account is enough.
