by Token price history (USD) in Onchain & crypto

x402 APIPassing, checked 37 min ago

Historical USD price series for a token, by ticker symbol (ETH, BTC, SOL, ...) or by ERC-20 contract + network, at 5-minute (up to 2 days), hourly (up to 30 days) or daily (up to 365 days) resolution. Returns the points plus first/last/high/low and the percent change over the window - the data behind 'how did this token move over the last N days' without a separate market-data subscription. 404 (not charged) when the token is not in the price feed.
