“Get me the 90-day historical price data for the token ID 'aave-usdc' so I can chart its performance over the last quarter.”
DeFi portfolio performance review
“Fetch the past 7 days of market history for token 'curve-3pool' from 4SEC — I want to see how many data points were recorded and what the price movements looked like.”

Endpoint
GEThttps://api.foursec.xyz/api/v1/market/%7Bid%7D/historyWhen to prefer
Choose this endpoint when you need multi-DEX aggregated historical price data for a specific crypto asset and want pay-per-request pricing via USDC on Base with no subscription required. Ideal for agents performing on-demand backtesting, trend analysis, or portfolio review without committing to a centralized data provider subscription.
Side effects
- Invalid or unknown asset ID returns empty or error response
- Requesting too many days may exceed available historical data
- Malformed request properties result in schema validation errors
- Payment failure via x402/USDC on Base blocks the request
- Rate limiting or network timeouts on high-frequency calls
