How this service works
Pay-per-use historical crypto investment calculator. Returns current value, ROI, peak value, and weekly price series.
Output
Returns the current USD value of the investment, the return on investment (ROI) percentage, the peak value the investment ever reached, and a weekly price series showing how the value evolved over time from the purchase date to today.
Example use cases
Evaluating a missed crypto opportunity
“I keep wondering what would have happened if I bought $5,000 of ETH on 2020-03-15 — can you tell me what it'd be worth now, the peak it hit, and the overall ROI?”
Proving crypto gains to a skeptic
“My friend thinks crypto is always a loss. Can you show him what $200 in SOL bought on 2023-01-10 would be worth today, including weekly price history so he can see the trend?”
Retrospective portfolio review
“I'm reviewing past decisions — what would a $2,500 investment in BTC made on 2019-07-04 look like today in terms of current value, ROI, and the all-time peak it reached?”

Use this endpoint when you need a quick, pay-per-use historical investment calculation for a specific cryptocurrency, including ROI, current value, peak value, and weekly price history.
