How this service works

Convert an amount between the main cryptocurrencies and ECB currencies (0.5 BTC to ETH, 100 USDT to EUR, 1000 EUR to SOL) with alternative.me prices (~190 largest coins) and ECB reference rates.

Output

Returns a JSON object with the converted amount (result), the exchange rate used (type), the original amount and source currency (amount, from), the target currency (a), the USD equivalent value (value_usd), and an ISO 8601 timestamp (date) of when the conversion was calculated.

Example use cases

Portfolio rebalancing in fiat terms

“I have 2.5 ETH and want to know how much that is in EUR right now — give me the live converted amount.”

Cross-chain DeFi swap planning

“I'm about to swap 1000 USDC for SOL. How much SOL would I get at current prices before I pull the trigger?”

Crypto payroll calculation

“I need to pay a contractor 3500 EUR. How much USDC should I send them at today's exchange rate?”

Technical details

Endpoint

POSThttps://api.vextorium.com/v1/crypto-convert?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need real-time conversion between cryptocurrencies and/or fiat currencies backed by DefiLlama and ECB data sources. Ideal when you need both crypto-to-crypto, fiat-to-crypto, and crypto-to-fiat conversions from a single endpoint. Prefer over generic exchange rate APIs when DeFi token support (SOL, ETH, BTC, USDC, etc.) combined with EUR-zone fiat rates is required.

Side effects

Unsupported or misspelled currency/token symbol returns an error or null result
DefiLlama or ECB price data unavailable causes conversion failure
Amount of zero or negative value may produce invalid result
Very obscure tokens without DefiLlama coverage will fail
Network timeout if external price feeds are slow to respond
