## When to prefer this

Choose this endpoint when you need cryptocurrency prices denominated in ECB-published fiat currencies (EUR, GBP, JPY, CHF, etc.) with traceable, authoritative sources — specifically on-chain USD prices from Chainlink or Uniswap v3 combined with official ECB reference rates. Prefer this over generic exchange-rate APIs when auditability of both the crypto price source and the FX conversion source matters, or when you need prices for Base network tokens in European currencies.

## Known failure modes

- Unsupported coin identifier returns an error or null price
- Currency code not published by ECB returns an error
- On-chain price feed unavailable for the requested token
- Network or RPC issues causing Chainlink/Uniswap data to be stale
- ECB rates not updated (weekends/holidays may use last published rates)
