Portfolio value at past date
“What was my crypto portfolio worth on December 31, 2023? Look up the historical average prices for Ethereum, Solana, and BNB in USD at that date using CoinStats so I can get an accurate end-of-year valuation.”
Reconstruct a past trade
“I'm trying to reconstruct a trade I made last year. Can you find the average price of Dogecoin in USD on July 4, 2023 using CoinStats? I want to verify what the market rate was at the exact time I sold.”

Endpoint
GEThttps://x402.coinstats.app/coins/price/avgWhen to prefer
Use this endpoint when you need the average market price of a specific cryptocurrency at a precise historical point in time — ideal for portfolio valuation, tax calculations, trade reconstruction, or cost-basis analysis. Prefer over live price endpoints when historical accuracy at a specific timestamp is required rather than real-time data.
