Technical details
Endpoint
POSThttps://twin.unykorn.org/defi/token-price-history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need historical USD price time series for a specific cryptocurrency token at daily or hourly granularity, especially for DeFi/on-chain analysis workflows. It is well-suited for backtesting, charting, trend analysis, and portfolio performance review, and supports up to 1 year of history. Prefer this over general market data APIs when operating in an x402 micropayment-native agent environment.
Side effects
- Invalid or unrecognized coin identifier (e.g. missing coingecko: prefix) returns an error
- days value outside 2–365 range is rejected
- Unsupported period value (not '1d' or '1h') causes a validation error
- Token not tracked by the underlying data source returns no data or 404
- Payment failure (x402) if USDC is not provided or insufficient
