MARKETCOMPASS — API KEY SETUP Configure these three personal credentials for the fullest supported coverage. Each enables its provider's feeds. All three are NOT required simply to open or use MarketCompass. Provider coverage, rate limits and plan access apply. MarketCompass Pro does not include or upgrade any data-provider subscription. 1. TIINGO API TOKEN Create or sign in to a Tiingo account: https://www.tiingo.com/ Find/copy your token using Tiingo's instructions: https://www.tiingo.com/blog/how-to-find-your-tiingo-api-token/ Used for daily price/NAV and historical-performance coverage for supported stocks, ETFs and mutual funds. 2. FINNHUB API TOKEN Register: https://finnhub.io/register Sign in and copy your API key: https://finnhub.io/dashboard Used for stock/ETF quote coverage. Earnings and research endpoints depend on the permissions included in your Finnhub plan. 3. COINGECKO DEMO API KEY Create/sign in to your CoinGecko account. Follow this official guide to register for Demo API access and generate a key in the Developer's Dashboard: https://docs.coingecko.com/docs/setting-up-your-api-key Used for cryptocurrency prices and supported history. Use a DEMO key. The current extension's Demo endpoint does not accept a paid CoinGecko Pro key as a substitute. Follow the provider's current plan terms and usage limits. SAVE AND REFRESH Open Dashboard > Settings & Sources > Source APIs. Paste the credentials into the corresponding Tiingo API token, Finnhub API token, and CoinGecko Demo API key fields. Click Save Source APIs, then Refresh All. Let the queued checks finish. Review diagnostics and the observation dates for the assets you follow. Saving a key does not guarantee coverage for every asset or historical period. Keys remain in local extension storage for the browser profile and are sent to the relevant provider for authentication. Do not email or publicly share keys. The MarketCompass Pro license key is separate from these API credentials. FX reference rates, Treasury yields and several other public-data feeds do not require these keys. Without one, its specific feeds can be unavailable even when another source supplies some prices. Start with appropriate free provider access where offered; never assume a paid upgrade is required or that a provider's free plan includes every feature. Support: marketcompassapp@gmail.com (never include your keys).
