## When to prefer this

Choose this endpoint when you need historical price data specifically for BTC, ETH, or SOL and are comfortable with a $0.01 USDC micropayment per call via x402 on Base Mainnet. Ideal for agents that need CoinGecko-sourced historical crypto price series for analysis, backtesting, or reporting, and already operate within the x402 payment protocol ecosystem.

## Known failure modes

- Unsupported coin symbol (only BTC, ETH, SOL are supported) returns an error or empty response
- Payment failure or insufficient USDC balance blocks access with a 402 response
- Invalid or malformed date range parameters may return empty or error data
- CoinGecko upstream downtime or rate limiting may cause delayed or failed responses
- Base Mainnet congestion may delay payment confirmation and API access
