How this service works
Convert an amount between cryptocurrencies and currencies (0.5 BTC to ETH, 100 USDC to EUR, 1000 EUR to SOL) with live DefiLlama prices and ECB rates.
Output
Returns a JSON object with the converted result amount, the exchange rate used (tipo), the source and destination symbols (de and a), the original amount (cantidad), the USD equivalent value (valor_usd), and the timestamp of the conversion (fecha).
Example use cases
Crypto portfolio rebalancing check
“If I sell 2 BTC, how many ETH could I buy with the proceeds at today's prices?”
Fiat off-ramp calculation
“I want to cash out 500 USDC — how many euros would I get at the current exchange rate?”
Crypto purchase from fiat budget
“I have 1000 euros to spend — how much SOL can I get for that right now?”
Technical details
Endpoint
POSThttps://api.vextorium.com/cripto-convertir-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a live, accurate conversion between any mix of cryptocurrencies and fiat currencies in a single call. It is especially useful when DefiLlama crypto prices and ECB fiat rates are the desired data sources, and when you need the USD equivalent alongside the converted amount. Prefer it over on-chain swap quotes (which include slippage and gas) when you only need a price reference, not an executable trade.
Side effects
- Unsupported or unrecognized currency/crypto symbol returns an error
- DefiLlama or ECB data temporarily unavailable causes fetch failure
- Invalid or missing required fields (cantidad, de, a) returns validation error
- Very low-liquidity tokens may have stale or missing prices
