How this service works
Daily price series of a token for up to 365 days with change, high, low, maximum drawdown and annualized volatility. Accepts symbols (BTC, ETH, SOL...) or chain:contract ids. Aggregated by DefiLlama.
Output
Returns a JSON object with the token's identifier and symbol, a day-by-day price array, the number of days requested, the initial and final prices, percentage change, maximum and minimum prices, maximum drawdown percentage, annualized volatility percentage, and the data source (DefiLlama aggregated).
Example use cases
Crypto portfolio risk assessment
“Get me the daily price history for BTC over the last 365 days — I want to see the annualized volatility, the maximum drawdown, and the overall price change so I can assess the risk profile.”
DeFi token performance review
“Pull the price chart for the past 60 days for the token at ethereum:0x6b175474e89094c44da98b954eedeac495271d0f — I need the high, low, and percentage change over that period.”
Volatility comparison for trading strategy
“I want to compare SOL's price volatility — can you get me the last 30 days of daily prices along with the annualized volatility and max drop percentage?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/price-chart?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured historical daily price data for a specific crypto token — especially when you also need derived statistics like volatility, drawdown, and percentage change pre-computed. It supports both well-known symbols (BTC, ETH, SOL) and obscure DeFi tokens via chain:contract identifiers, making it more flexible than endpoints limited to top-tier assets. Prefer it over raw price feeds when you want a ready-to-use analytics payload without additional computation.
Side effects
- Unknown or unsupported token symbol returns null or empty series
- Invalid chain:contract address format causes a parsing error
- Requesting more than 365 days may be rejected or capped
- Token with insufficient price history returns a shorter series than requested
- Network or upstream DefiLlama data outage causes missing data points
