Technical details
Endpoint
GEThttps://rest.coincap.io/v3/agentFriendly/history/bitcoinWhen to prefer
Use this endpoint when you need a quick, agent-friendly historical price series for a specific cryptocurrency by slug (e.g. 'bitcoin', 'ethereum'). Prefer this over raw exchange APIs or full market data providers when you want a simple, pre-formatted time series with minimal overhead and a low per-call cost. If you need technical indicators like MACD or EMA, use the sibling indicator endpoints instead.
Side effects
- Invalid or unknown asset slug returns an error or empty response
- Capped data points limit — only a maximum number of data points returned, not full granular history
- Payment failure (x402) if the $0.01 USDC call fee is not satisfied
- Network timeout or service unavailability from CoinCap servers
