Technical details
Endpoint
GEThttps://www.blockchainiq.co/api/x402/v1/history/%7BcoinId%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need analyst-verified daily historical price data for individual cryptocurrencies at low cost ($0.03/call), especially when you want reliable CoinGecko-mapped coin IDs and clean date/price_usd output for charting, analysis, or backtesting — without paying institutional data subscription fees. Prefer this over raw CoinGecko API calls when you want a curated, pay-per-use model with no API key management.
Side effects
- Invalid coinId returns an error or empty dataset — must use exact CoinGecko coin identifier (e.g. 'bitcoin', not 'BTC')
- Days parameter outside 1-730 range will be rejected by schema validation
- Payment failure (x402) if USDC balance is insufficient — endpoint requires $0.03 USDC per call
- Network timeout if the upstream data provider is slow or unavailable
- Unknown or delisted coins may return no data or a not-found error
