Output
A JSON object containing the cryptocurrency symbol, CoinGecko ID, the vs_currency (usd), the number of days covered, the number of data points, and an array of time-series points each with a UTC timestamp, price in USD, trading volume, and market capitalization.
Example use cases
Crypto portfolio performance review
“Pull the last 30 days of price and market cap history for ETH so I can see how my portfolio has been performing recently.”

Technical details
Endpoint
GEThttps://x402financialdata.com/crypto-history/%7Bsymbol%7DWhen to prefer
Choose this endpoint when you need historical cryptocurrency price, volume, and market cap data on a pay-per-call basis without committing to an API subscription or managing API keys. It is ideal for agents that need occasional or sporadic crypto data lookups billed in micropayments (USDC on Base or Solana). Prefer it over subscription-based data providers when usage is infrequent or cost-per-query economics are favorable.
Side effects
- Invalid or unrecognized symbol returns an error or empty dataset
- Payment failure via x402 if wallet has insufficient USDC on Base or Solana
- Rate limiting or upstream CoinGecko outage resulting in stale or unavailable data
- Malformed symbol path parameter causing a 404 or bad request response
