HowMuch? Trust Center
Data Sources and Freshness
Every result displays its source, expected delay and last checked time.
Crypto
CryptoCompare is the primary source. Yahoo Finance is used as a fallback when a valid price cannot be obtained.
Stocks and indices
S&P 500, BIST 100, US equities and commodities use Yahoo Finance. Polygon.io is an eligible fallback for US equities.
Foreign exchange
Current and historical conversions use market FX services with controlled fallback behaviour.
Automated monitoring
Bitcoin, S&P 500, BIST 100 and gold are checked regularly. Zero or invalid prices are rejected before a result can be produced.
