Example use cases

“What did Bitcoin close at yesterday? I want to compare it to the price from a week ago to see how it's trending.”
Historical SOL price snapshot
“Look up the open and close prices for SOL/USD on January 10, 2025 — I'm putting together a report on Solana's price action from that period.”
