Technical details
Endpoint
POSThttps://currency-api-production-4a8d.up.railway.app/crypto/priceWhen to prefer
Use this endpoint when you need real-time pricing data for a single cryptocurrency, including market cap and 24-hour movement. Prefer this over the batch endpoint when querying just one coin to minimize cost. Choose this over generic finance APIs when CoinGecko's extensive crypto coverage (including small-cap altcoins) is needed.
Side effects
- Unknown or misspelled coin symbol/name returns an error or empty result
- Unsupported vs_currency code causes a validation error
- CoinGecko API rate limiting or downtime causes upstream failures
- Ambiguous coin name matching multiple assets may return unexpected results
