Server instructions

OptionWhales: US options-flow and stock market data — unusual options activity, dealer gamma (GEX) levels, implied volatility, open interest, dark pool, earnings positioning, plus stock quotes, candles, technicals, fundamentals, news, short interest and insider trades. A small preview works with no key or sign-in: SPY and QQQ gamma levels, the next high-impact macro events and earnings reporters, the top options-flow tickers and the latest unusual trades. Everything else needs an API key, sent as the X-API-Key header or attached with use_api_key. No key yet? Call register_free_key with the email of the person you are helping: the key works immediately, and they confirm it from the email OptionWhales sends (you may read the code from their inbox and call confirm_registration). Free keys get previews (top results, SPY/QQQ gamma levels, mega-cap implied volatility, the economic calendar); Pro ($19/mo, https://optionwhales.io/pricing) unlocks every tool. Data is for research and education, not investment advice.
